Bradykardia
Leczenie
Bradykardia definiowana jest jako częstość akcji serca poniżej 60 uderzeń na minutę i wymaga leczenia zależnego od etiologii, nasilenia objawów oraz chorób współistniejących. U pacjentów bezobjawowych leczenie może nie być konieczne, natomiast u osób z objawami takimi jak zawroty głowy, omdlenia, zmęczenie czy duszność, terapia ma na celu zwiększenie częstości akcji serca, poprawę perfuzji narządowej oraz zapobieganie powikłaniom. Pierwszym krokiem jest identyfikacja i eliminacja odwracalnych przyczyn, takich jak działania niepożądane leków (beta-blokery, blokery kanału wapniowego, digoksyna), zaburzenia elektrolitowe (np. hiperkaliemia), niedoczynność tarczycy, choroba Lyme’a, hipoksja czy ostre niedokrwienie mięśnia sercowego. W stanach ostrych z niestabilnością hemodynamiczną stosuje się atropinę w dawce 0,5-1,0 mg i.v. co 3-5 minut do maksymalnej dawki 3 mg, a w przypadku braku efektu – wlewy dożylne adrenaliny (2-10 μg/min) lub dopaminy (2-20 μg/kg/min).

Leczenie bradykardii – wprowadzenie
Bradykardia to stan, w którym serce bije zbyt wolno, zwykle poniżej 60 uderzeń na minutę. Leczenie bradykardii zależy od przyczyny, nasilenia objawów oraz obecności innych chorób współistniejących. U pacjentów bezobjawowych często nie jest wymagane żadne leczenie, natomiast u osób z objawami klinicznymi (takimi jak zawroty głowy, omdlenia, zmęczenie, duszność czy hipotensja) terapia jest niezbędna, aby zapobiec poważnym powikłaniom12.
Celem leczenia bradykardii jest zwiększenie częstości akcji serca do wartości, która zapewni odpowiednią perfuzję narządów, złagodzenie objawów i zapobieganie poważnym komplikacjom, takim jak omdlenia, upadki czy nawet nagły zgon sercowy34.
Identyfikacja i leczenie przyczyn bradykardii
Pierwszym krokiem w terapii bradykardii powinna być identyfikacja i leczenie przyczyny podstawowej56. Do najczęstszych odwracalnych przyczyn bradykardii należą:
- Działania niepożądane leków (beta-blokery, blokery kanału wapniowego, digoksyna)7
- Zaburzenia elektrolitowe (szczególnie hiperkaliemia)8
- Niedoczynność tarczycy9
- Choroba Lyme’a10
- Hipoksja11
- Zwiększone ciśnienie śródczaszkowe12
- Ostre niedokrwienie mięśnia sercowego13
Gdy bradykardia wynika z działania niepożądanego leków (np. beta-blokerów, antagonistów wapnia), modyfikacja leczenia poprzez zmniejszenie dawki lub całkowite odstawienie leku może prowadzić do ustąpienia objawów1415. W przypadku chorób współistniejących, takich jak niedoczynność tarczycy, leczenie choroby podstawowej (np. levotyroksyna) może rozwiązać problem bradykardii16.
Farmakoterapia bradykardii
W sytuacjach ostrych, gdy bradykardia powoduje niestabilność hemodynamiczną, stosuje się leki zwiększające częstość akcji serca17. Do najważniejszych należą:
Atropina
Atropina jest lekiem pierwszego wyboru w objawowej bradykardii. Działa poprzez blokowanie działania nerwu błędnego na serce, co zwiększa częstość akcji serca1819. Standardowe dawkowanie to 0,5-1,0 mg dożylnie co 3-5 minut, do maksymalnej dawki całkowitej 3 mg20. Atropina jest szczególnie skuteczna w bradykardii zatokowej i bloku przedsionkowo-komorowym pierwszego stopnia, natomiast może być nieskuteczna w bloku AV typu Mobitz II lub bloku całkowitym21.
Leki inotropowe i chronotropowe
Jeśli atropina jest nieskuteczna, można zastosować wlew dożylny leków o działaniu inotropowym i chronotropowym22:
- Adrenalina (epinefryna) – w dawce 2-10 μg/min w ciągłym wlewie dożylnym23
- Dopamina – w dawce 2-20 μg/kg/min24
Teofilina
U pacjentów w podeszłym wieku z przewlekłą objawową bradykardią, którzy nie kwalifikują się do implantacji stymulatora, można rozważyć zastosowanie teofiliny. Zalecane dawki to 400-600 mg/dobę (około 8 mg/kg/dobę) w dawkach podzielonych, co powinno zapewnić stężenie w surowicy między 5 a 15 mg/l25.
Teofilina powinna być stosowana ostrożnie, z uwzględnieniem czynników modyfikujących jej metabolizm (np. palenie tytoniu), interakcji lekowych (np. ciprofloksacyna) oraz chorób współistniejących (np. choroby wątroby, niewydolność serca). Lek ten jest przeciwwskazany w zespole chorego węzła zatokowego z naprzemiennymi epizodami tachykardii i bradykardii oraz w przypadku częstych pobudzeń ektopowych z komór26.
Elektrostymulacja serca w leczeniu bradykardii
Gdy bradykardia jest objawowa i nie reaguje na leczenie farmakologiczne lub wynika z trwałego uszkodzenia układu przewodzącego serca, wskazane jest zastosowanie stymulacji elektrycznej27.
Czasowa stymulacja serca
W stanach ostrych, gdy bradykardia powoduje niestabilność hemodynamiczną i nie reaguje na leczenie farmakologiczne, stosuje się czasową stymulację serca28:
- Stymulacja przezskórna (transcutaneous pacing, TCP) – jest metodą nieinwazyjną, stosowaną w sytuacjach nagłych. Polega na umieszczeniu elektrod na skórze klatki piersiowej i dostarczaniu impulsów elektrycznych, które powodują skurcz mięśnia sercowego. Metoda ta może być bolesna dla przytomnego pacjenta i wymaga rozważenia sedacji2930.
- Stymulacja przezżylna (transvenous pacing) – polega na wprowadzeniu elektrody do prawej komory przez żyłę szyjną lub podobojczykową. Jest bardziej inwazyjna, ale też bardziej efektywna (skuteczność >95%). Stosowana jako pomost do wszczepienia stymulatora stałego3132.
Stały stymulator serca (rozrusznik)
Implantacja stałego stymulatora serca jest najskuteczniejszą metodą leczenia objawowej bradykardii, szczególnie gdy wynika ona z trwałego uszkodzenia układu przewodzącego serca3334. Zgodnie z wytycznymi towarzystw kardiologicznych, implantacja stymulatora jest wskazana w następujących przypadkach:
- Objawowa bradykardia zatokowa, w tym zespół chorego węzła zatokowego35
- Objawowy blok przedsionkowo-komorowy drugiego stopnia typu Mobitz II36
- Blok przedsionkowo-komorowy trzeciego stopnia (całkowity)37
- Naprzemienne bloki odnóg pęczka Hisa38
- Omdlenia z blokiem odnogi pęczka Hisa i wysokim ryzykiem bloku przedsionkowo-komorowego39
Tradycyjny stymulator serca to małe urządzenie umieszczane pod skórą, najczęściej pod obojczykiem, podczas zabiegu chirurgicznego. Stymulator monitoruje rytm serca i wysyła impulsy elektryczne, gdy wykryje zbyt wolną czynność serca40. Współczesne stymulatory są wysoce efektywne (skuteczność >95%), a ich baterie mogą działać przez wiele lat, nawet ponad dekadę41.
Bezprzewodowe stymulatory serca
Nowszą opcją są bezprzewodowe stymulatory serca (leadless pacemakers), które można implantować bezpośrednio do serca poprzez zabieg małoinwazyjny z użyciem cewnika wprowadzanego przez duże naczynie krwionośne4243. Te urządzenia są bardzo małe (niewiele większe od dużej kapsułki witaminowej) i pozwalają pacjentowi na szybszy powrót do zdrowia po zabiegu w porównaniu do tradycyjnej metody chirurgicznej44.
Stymulacja resynchronizująca
U pacjentów z bradykardią i współistniejącą niewydolnością serca można zastosować stymulator resynchronizujący (CRT, Cardiac Resynchronisation Therapy). Urządzenia CRT mają na celu resynchronizację pracy lewej i prawej komory, co poprawia funkcję serca. W przypadku CRT implantuje się trzecią elektrodę, która pomaga synchronizować pracę obu komór i poprawić wydajność serca45.
Zmiany stylu życia w leczeniu bradykardii
W przypadkach mniej nasilonych bradykardii, zalecane są zmiany stylu życia ukierunkowane na zdrowe nawyki dotyczące serca4647:
- Zaprzestanie palenia tytoniu
- Ograniczenie spożycia alkoholu
- Regularna aktywność fizyczna
- Stosowanie diety bogatej w owoce, warzywa i pełne ziarna
- Utrzymanie prawidłowej masy ciała
- Redukcja stresu
- Właściwe nawodnienie organizmu
Te zmiany stylu życia mogą pomóc w regulacji rytmu serca i poprawie ogólnego stanu zdrowia układu sercowo-naczyniowego4849.
Postępowanie w stanach nagłych przy bradykardii
W przypadku niestabilnej bradykardii wymagającej natychmiastowej interwencji, postępowanie powinno być zgodne z wytycznymi zaawansowanych zabiegów resuscytacyjnych (ACLS)5051:
- Ocena stanu klinicznego pacjenta i monitorowanie podstawowych parametrów życiowych
- Zapewnienie drożności dróg oddechowych i podanie tlenu w przypadku hipoksemii
- Założenie dostępu dożylnego
- Wykonanie 12-odprowadzeniowego EKG
- Identyfikacja i leczenie odwracalnych przyczyn bradykardii (hipoksja, zaburzenia elektrolitowe, toksyny)
- Podanie atropiny 0,5-1,0 mg i.v. co 3-5 minut do maksymalnej dawki 3 mg
- Jeśli brak odpowiedzi na atropinę – rozpoczęcie czasowej stymulacji przezskórnej
- Równolegle można rozważyć wlew dopaminy (2-20 μg/kg/min) lub adrenaliny (2-10 μg/min)
- W przypadku braku poprawy – konsultacja kardiologiczna i rozważenie czasowej stymulacji przezżylnej
W przypadku bradykardii związanej z hipotermią, atropina i stymulacja elektryczna zwykle nie są zalecane ze względu na potencjalną drażliwość mięśnia sercowego. Głównym sposobem leczenia jest ogrzewanie i leczenie podtrzymujące52.
Monitorowanie i długoterminowa opieka nad pacjentem z bradykardią
Pacjenci z bradykardią wymagają regularnego monitorowania i długoterminowej opieki53:
- Regularne wizyty kontrolne u kardiologa
- Okresowa kontrola parametrów pracy stymulatora serca (jeśli został wszczepiony)
- Monitorowanie objawów i skuteczności leczenia
- Edukacja pacjenta na temat objawów, które powinny skłonić do natychmiastowej konsultacji medycznej
- Właściwa kontrola chorób współistniejących
Pacjenci z wszczepionym stymulatorem serca powinni być świadomi pewnych ograniczeń i środków ostrożności, takich jak unikanie silnych pól elektromagnetycznych czy informowanie personelu medycznego o posiadaniu stymulatora przed wykonaniem procedur diagnostycznych lub terapeutycznych54.
Wskazania do implantacji stymulatora serca
Decyzja o implantacji stymulatora serca powinna być podejmowana indywidualnie, biorąc pod uwagę korzyści i potencjalne ryzyko związane z zabiegiem55. Zgodnie z wytycznymi American College of Cardiology, American Heart Association i Heart Rhythm Society, stała stymulacja serca jest zalecana w następujących sytuacjach5657:
Wskazania klasy I (silne zalecenie)
- Objawowa bradykardia zatokowa, włączając zespół chorego węzła zatokowego z udokumentowaną korelacją objawów z bradykardią
- Objawowy blok przedsionkowo-komorowy drugiego stopnia typu Mobitz II
- Objawowy blok przedsionkowo-komorowy trzeciego stopnia (całkowity)
- Naprzemienne bloki odnóg pęczka Hisa
- Omdlenie z udokumentowanym blokiem AV, które wymaga leczenia
Wszczepienie stymulatora nie jest zalecane w bradykardii bezobjawowej, bradykardii spowodowanej odwracalnymi przyczynami, czy bradykardii występującej tylko podczas snu, nawet jeśli jest ciężka5859.
Podsumowanie leczenia bradykardii
Leczenie bradykardii powinno być dostosowane do indywidualnych potrzeb pacjenta, z uwzględnieniem przyczyny, nasilenia objawów i chorób współistniejących60. Kluczowe elementy postępowania obejmują:
- Identyfikację i leczenie odwracalnych przyczyn
- Modyfikację leczenia farmakologicznego, jeśli bradykardia jest spowodowana lekami
- Farmakoterapię w przypadku objawowej bradykardii, szczególnie w stanach ostrych
- Implantację stymulatora serca w przypadku trwałego uszkodzenia układu przewodzącego serca
- Wprowadzenie zmian stylu życia w celu poprawy ogólnego stanu zdrowia układu sercowo-naczyniowego
- Regularne monitorowanie i długoterminową opiekę kardiologiczną
Wczesna diagnoza i odpowiednie leczenie bradykardii mogą znacząco zmniejszyć ryzyko powikłań i poprawić jakość życia pacjentów61. Współczesne metody leczenia, w tym zaawansowane systemy stymulacji serca, pozwalają na skuteczne kontrolowanie rytmu serca i zapewnienie pacjentom aktywnego stylu życia62.

A patient with sinus bradycardia should be evaluated for hemodynamic instability. If found to be hemodynamically unstable, the patient can be treated with intravenous (IV) atropine 0.5 mg push every 3 to 5 minutes up to 3 mg total. If the patient’s symptoms and heart rate do not improve, the patient is a candidate for a temporary pacemaker. […] While management decisions are being made for a patient with sinus bradycardia, the patient’s medication list should also be reviewed for possible causes of bradycardia, and those medications should be withdrawn if possible. If a patient has comorbid conditions that require him to be on certain medications, which may be causing the sinus bradycardia, then in that case-patient may be a candidate for a permanent pacemaker. In cases where medication can be withdrawn, withdrawal is made, and if symptoms and heart rate still do not improve, then the patient may be evaluated for a permanent pacemaker.

Treatment for bradycardia depends on how severe the symptoms are and the cause of the slow heart rate. If you don’t have symptoms, treatment might not be needed. […] Bradycardia treatment may include: […] A medical device called a pacemaker. […] If you have severe bradycardia symptoms and other treatments aren’t possible, your health professional may suggest a device called a pacemaker. […] A pacemaker is placed under the skin near the collarbone during a minor surgery. The device helps fix a slow heartbeat. When the heart beats too slowly, the pacemaker sends electrical signals to the heart to speed up the beat.
- #3 Bradycardia: Symptoms, Causes & Treatmenthttps://my.clevelandclinic.org/health/diseases/17841-bradycardia
If you have bradycardia but don’t have any symptoms, it’s unlikely that you need treatment. For those who do have symptoms, bradycardia is almost always treatable and is sometimes curable. If you have bradycardia because of another medical condition, sometimes treating that condition is all it takes to stop your bradycardia. An example of this is when you have bradycardia because of a medication you’re taking. […] There are two primary ways to treat bradycardia. […] If bradycardia is causing significant problems such as dangerously low blood pressure, an intravenous (IV) or injectable medication such as atropine can cause your heart to beat faster. Treatments like this are usually hospital-specific because people receiving these medications may need monitoring and additional care. […] For many people with bradycardia, a permanent pacemaker is the best way to treat this condition. This is especially effective with conditions like sick sinus syndrome, where your heart’s natural pacemaker cells aren’t working properly.

How is bradycardia treated? […] How bradycardia is treated depends on what is causing it. Treatment also depends on the symptoms. If bradycardia doesn’t cause symptoms, it may not be treated. You and your doctor can decide what treatment is right for you. […] If damage to the heart’s electrical system causes your heart to beat too slowly, you may get a pacemaker. A pacemaker is an implanted device that helps correct the slow heart rate. […] […] If another medical problem, such as hypothyroidism or an electrolyte imbalance, is causing a slow heart rate, treating that problem may cure the bradycardia. […] […] If a medicine is causing your heart to beat too slowly, your doctor may adjust the dose or prescribe a different medicine. […] The goal of treatment is to raise your heart rate and relieve symptoms. For certain types of bradycardia, treatment may help prevent serious problems. These problems include fainting, injuries from fainting, and even death.

If sinus bradycardia is asymptomatic or produced by a reversible cause, according to the guidelines, pacing is not indicated. […] In patients with sinus bradycardia secondary to therapeutic use of digitalis, beta-blockers, or calcium channel blockers, simple discontinuation of the drug, along with monitored observation, are often all that is necessary. Occasionally, intravenous atropine and temporary pacing are required. […] Treatment of postinfectious bradycardia usually requires permanent pacing. […] In patients with hypothermia who have confirmed sinus bradycardia with a pulse, atropine and pacing are usually not recommended because of myocardial irritability. Rewarming and supportive measures are the mainstays of therapy. […] Treatment of inadequate perfusion would include pressors, atropine, and pacing. […] Regular follow-up care is necessary for patients in whom a permanent pacemaker is placed.

Bradycardia Treatment […] Treatment depends on the type and severity of bradycardia and may include lifestyle changes, changes in medication, temporary or permanent pacemaker placement, or intravenous medications. […] Acute bradycardia requires a stepwise approach to management. After determining that the patient is hemodynamically stable, clinicians should assess and treat reversible causes of bradycardia. Simultaneously, patients with moderate to severe symptoms should receive atropine. Options for acute medical management of bradycardia attributable to SND or AV block include dopamine, epinephrine, and glucagon. […] Patients who continue to have severe symptoms with hemodynamic instability require acute pacing. […] When diagnosing SND, clinicians must rule out reversible causes. Reversible or treatable causes of SND include medications, metabolic abnormalities, acute myocardial ischemia or infarction, infections, toxins, and cardiac surgery.

There are three medications used in the bradycardia algorithm: atropine, epinephrine, and dopamine. Read about each drug and its use within the bradycardia algorithm below. […] When symptomatic bradycardia occurs, the primary objective is to identify and treat the cause of the problem. Medications are indicated if symptomatic bradycardia cannot be corrected by treating an underlying cause or if the cause cannot be determined. […] Atropine is the first line medication for the treatment of bradycardia. The administration of atropine typically causes an increase in heart rate. This increase in the heart rate occurs when atropine blocks the effects of the vagus nerve on the heart. […] The dosing for Atropine is 1 mg IV every 3-5 minutes as needed, and the maximum total dosage for administration is 3 mg.

Atropine should be avoided with bradycardia caused by hypothermia and, in most cases, it will not be effective for Mobitz type II/Second-degree block type 2 or complete heart block. […] Transcutaneous pacing should be the first line action for symptomatic Mobitz II and symptomatic complete heart block. It is very safe & less painful than in previous times due to technological improvements. […] Epinephrine and dopamine are second-line drugs for symptomatic bradycardia.

If you have bradycardia but don’t have any symptoms, it’s unlikely that you need treatment. For those who do have symptoms, bradycardia is almost always treatable and is sometimes curable. If you have bradycardia because of another medical condition, sometimes treating that condition is all it takes to stop your bradycardia. An example of this is when you have bradycardia because of a medication you’re taking. […] There are two primary ways to treat bradycardia. […] If bradycardia is causing significant problems such as dangerously low blood pressure, an intravenous (IV) or injectable medication such as atropine can cause your heart to beat faster. Treatments like this are usually hospital-specific because people receiving these medications may need monitoring and additional care. […] For many people with bradycardia, a permanent pacemaker is the best way to treat this condition. This is especially effective with conditions like sick sinus syndrome, where your heart’s natural pacemaker cells aren’t working properly.

In severe cases of bradycardia, treatment may require a pacemaker. These devices are surgically implanted and attached to the heart. A pacemaker can help prevent a heart from beating too slowly by pulsing electrical signals at the right time and with the correct strength. When a heart begins to beat too slowly, the pacemaker emits an electric signal that causes the heart to beat faster. […] Depending on the severity and source of your bradycardia, you may be able to recover by treating an underlying cause. However, in many cases, bradycardia is treated and managed rather than cured or fixed. Treatments often involve heart-healthy lifestyle changes and may include a surgically implanted pacemaker in more serious cases.
