• #1 Supraventricular tachycardia: An overview of diagnosis and management

  https://pmc.ncbi.nlm.nih.gov/articles/PMC6964177/

  Supraventricular tachycardia (SVT) is a common cause of hospital admissions and can cause significant patient discomfort and distress. The prevalence of SVT is 2.25/1000 persons with a female predominance of 2:1 across all age groups. SVT increases patient morbidity, particularly when symptoms are frequent or incessant, and in a small cohort of patients with atrial fibrillation (AF) and ventricular pre-excitation, it can be life-threatening. […] Long-term management is contingent on the underlying mechanism, frequency of symptoms, patient safety and preference. However, the potential for substantial improvements in quality of life, reduced hospital attendances and cost burden make catheter ablation a particularly desirable option as first line therapy for all SVTs, especially in AVNRT and AVRT where documented cure rates can exceed 95% with an associated risk of 1% for major complications. […] Supraventricular tachycardia is a common cause of hospital attendance and acute admission.

  How common is supraventricular tachycardia? (Epidemiology) The prevalence of SVT is 2.25/1,000 persons and the incidence is 35/100,000 person-years. […] Women have a two times greater risk of developing SVT than men. […] People aged over 65 years have more than five times the risk of developing SVT than younger individuals. […] In a paediatric cohort study of almost 2 million live births between 2000 and 2008, 2,021 patients (51.6% male, overall incidence 1.03/1000) had SVT (Wolff-Parkinson-White (WPW) syndrome accounted for 16.2%). By the age of 15 years, the annual risk of sudden death was 0.01% per patient-year. […] In the general population, the prevalence of a WPW pattern on ECG ranges from 0.15-0.25%, increasing to 0.55% among first-degree relatives of affected patients. However, not all patients develop SVT and intermittent pre-excitation is not rare.

• #3 Common Types of Supraventricular Tachycardia: Diagnosis and Management | AAFP

  https://www.aafp.org/pubs/afp/issues/2010/1015/p942.html

  A more recent article on common types of supraventricular tachycardia is available. […] The most common types of supraventricular tachycardia are caused by a reentry phenomenon producing accelerated heart rates. […] SVTs (excluding atrial fibrillation or flutter and multifocal AT) have an estimated incidence of 35 per 100,000 person-years, with a prevalence of 2.29 per 1,000 persons. […] Although AVNRT is the most common SVT in adults (approximately 50 to 60 percent), AVRT is most common in children (accounts for approximately 30 percent of all SVTs).

  https://www.thecardiologyadvisor.com/ddi/svt-supraventricular-tachycardia/

  The estimated prevalence of SVT is 168 to 332 cases per 100,000 individuals, with female patients constituting 67.5% of cases. Approximately one-half of patients with SVT are age 45 to 64 years. […] SVT is generally not life-threatening, and the prognosis is usually good in the absence of structural heart disease. Many asymptomatic patients do not need SVT treatment and have a generally benign disease course. Patients with more severe symptoms or comorbid heart disease may require earlier acute therapy intervention and long-term management. Rarely, SVT can cause sudden cardiac death. […] Guidelines relevant to the care of patients with SVT include the following: 2015 ACC/AHA/HRS Guideline for the Management of Adult Patients With Supraventricular Tachycardia; and 2019 ESC Guidelines for the Management of Patients with Supraventricular Tachycardia.

• #5 Paroxysmal Supraventricular Tachycardia: Background, Etiology, Epidemiology

  https://emedicine.medscape.com/article/156670-overview

  The incidence of paroxysmal SVT is approximately 36 per 100,000 persons. […] Atrial fibrillation is the most common, affecting 3 million people in the United States alone, with prevalence of 0.4-1% in the population. It is estimated that atrial fibrillation will affect more than 7.5 million people by 2050. […] In a population-based study, the incidence of paroxysmal SVT was 35 cases per 100,000 person-years and peak incidence was in the middle age people. […] AVNRT is more common in patients who are middle-aged or older, while adolescents are more likely to have SVT mediated by an accessory pathway like AVRT. […] The incidence rate of the WPW pattern on ECG tracings is 0.1-0.3% in the general population, although not all patients develop SVT. […] Paroxysmal SVT is observed not only in healthy individuals; it is also common in patients with previous myocardial infarction, mitral valve prolapse, rheumatic heart disease, pericarditis, pneumonia, chronic lung disease, and current alcohol intoxication.

  https://www.mja.com.au/journal/2009/190/5/supraventricular-tachycardia

  Supraventricular tachycardia (SVT) is a common cardiac rhythm disturbance; it usually presents with recurrent episodes of tachycardia, which often increase in frequency and severity with time. […] The incidence of SVT is about 35 cases per 100 000 population per year, with a prevalence of 2.25 cases per 1000 population. […] For the three most common types of SVT, peak incidence of presentation for ablation occurs in the middle decades of life: at 36 years for AVRT, 48 years for AVNRT, and 50 years for AT. […] A significant proportion of patients have symptoms for a prolonged period ( 1 year) before the diagnosis of SVT is made, and occasionally episodes are misdiagnosed as anxiety or panic disorders. […] Long-term management is individualised based on the frequency and severity of episodes and the impact of symptoms on quality of life. […] Definitive treatment of SVT is indicated in patients who have recurrent symptomatic episodes of SVT that affect their quality of life. […] Radiofrequency catheter ablation is recommended for most of these patients. It has a low risk of complications, and is curative in more than 95% of patients.

  Atrioventricular nodal reentrant tachycardia has an incidence of 35 per 10,000 person-years, or 2.29 per 1000 individuals, making it the most common tachyarrhythmia among young adults. Women are at a 2-fold higher risk of developing paroxysmal supraventricular tachycardia compared to men, whereas older individuals have a 5-fold increased risk compared to younger individuals. […] Supraventricular tachycardia is the most common symptomatic arrhythmia in infants and children. Children with congenital heart diseases, such as the Ebstein anomaly of the tricuspid valve, are at higher risk for atrioventricular reciprocating tachycardia. In addition, young adults who have undergone Fontan surgery or surgery for tetralogy of Fallot are at an increased risk for atrial arrhythmias. In children younger than 12, an accessory atrioventricular pathway causing reentrant tachycardia is the most prevalent cause of supraventricular tachycardia.

• #15 Supraventricular Tachycardia (SVT) • LITFL • ECG Library Diagnosis

  The term supraventricular tachycardia (SVT) refers to any tachydysrhythmia arising from above the level of the Bundle of His, and encompasses regular atrial, irregular atrial, and regular atrioventricular tachycardias. […] AVNRT is typically paroxysmal and may occur spontaneously or upon provocation with exertion, caffeine, alcohol, beta-agonists (salbutamol) or sympathomimetics (amphetamines). […] It is more common in women than men (~ 75% of cases occurring in women) and may occur in young and healthy patients as well as those suffering chronic heart disease. […] The condition is generally well tolerated and is rarely life threatening in patients with pre-existing heart disease. […] Most other types of SVT are discussed elsewhere (follow links in classification table).

• #16 Diagnosis and Management of Common Types of Supraventricular Tachycardia | AAFP

  https://www.aafp.org/pubs/afp/issues/2015/1101/p793.html

  Supraventricular tachycardia refers to rapid rhythms that originate and are sustained in atrial or atrioventricular node tissue above the bundle of His. The overall prevalence of SVT is two or three per 1,000 persons in the general population. The mean age of occurrence is 45 years, and 62% of cases occur in women. AVNRT is the most common type of SVT in adults. SVT occurs in one per 250 to 1,000 infants and children, with AVRT accounting for most cases. […] The incidence of AVNRT in women is twice that in men. It is correlated with lower estrogen levels and higher progesterone levels, and is therefore more common during the luteal phase of the menstrual cycle and less common during pregnancy. AVNRT involves a pattern of reentry in persons who have two pathways in their atrioventricular (AV) node, one slow and one fast. […] The second most common type of SVT is AVRT. There is a progressive decline in the proportion of SVT caused by AVRT as age increases, from 60% in the first decade of life to 9% after 70 years of age.

  What is a Supraventricular Tachycardia? In some hearts, an abnormal heart rhythm develops in the top part of the heart when an electrical impulse either starts from a different location other than the SA node, or follows a route (or pathway) that is not normally present. When this occurs the heart will suddenly start racing. The heart rate is usually over 150 beats per minute and often over 200 beats per minute. Certain things in some people can trigger episodes. These include caffeine, alcohol, anxiety, exercise or sudden movements such as bending over. However, often these episodes can occur at any time without a trigger. During an episode, you will usually be aware of the rapid beating of your heart. […] In the vast majority of cases SVT is a benign condition. This means that it will not cause sudden death, will not damage the heart or cause a heart attack and will not shorten life expectancy. There are some rare exceptions that will be discussed with you if relevant. […] There are 3 main types of SVT. It will not always be obvious which type of SVT you have prior to the electrical study of your heart. […] There are 3 main options for people with SVT.

[…] AVNRT is the most common type of SVT, making up around 50-60% of SVT cases. […] AVRT is the second-most common type of SVT and often occurs in people with a congenital disorder called Wolff-Parkinson-White syndrome. […] Getting a diagnosis of SVT can be challenging. […] If you have symptoms of SVT, your doctor may recommend having your heart rhythm recorded using a wearable heart monitor. […] If medication proves unsuccessful or if you prefer to avoid drugs, your doctor may recommend an electrophysiology study followed by catheter ablation. […] This procedure is highly successful in most patients over 95% of patients that undergo catheter ablation for SVT are cured.

  Supraventricular tachycardia (SVT) is the name given to the condition where the heart beats extremely fast but in a regular fashion for a period of minutes to hours. […] SVT may be caused by an additional electrical pathway that forms when the baby’s heart is developing in the womb. […] The additional pathway causes episodes where the heart rate suddenly quickens to an abnormally fast rate, often around 200 beats per minute. […] In most cases SVT is diagnosed on an electrocardiogram (ECG) at the time of symptoms of heart racing. […] SVT is confirmed using an ECG, which shows abnormal rhythm during an episode. […] For people with symptoms that are affecting their day to day life, or who have significant episodes, medication can be offered. […] The most effective long term treatment for SVT is cardiac ablation. […] Most episodes of supraventricular tachycardia (SVT) only last for a few minutes and do not need urgent treatment. […] If an episode lasts for a prolonged period, doctors in the AE will try some 'tricks’ to try to slow the heart.

  How common is supraventricular tachycardia? (Epidemiology) The prevalence of SVT is 2.25/1,000 persons and the incidence is 35/100,000 person-years. […] Women have a two times greater risk of developing SVT than men. […] People aged over 65 years have more than five times the risk of developing SVT than younger individuals. […] In a paediatric cohort study of almost 2 million live births between 2000 and 2008, 2,021 patients (51.6% male, overall incidence 1.03/1000) had SVT (Wolff-Parkinson-White (WPW) syndrome accounted for 16.2%). By the age of 15 years, the annual risk of sudden death was 0.01% per patient-year. […] In the general population, the prevalence of a WPW pattern on ECG ranges from 0.15-0.25%, increasing to 0.55% among first-degree relatives of affected patients. However, not all patients develop SVT and intermittent pre-excitation is not rare.

  Supraventricular tachycardia (soo pruh ven TRIK yuh ler tack ih KAR dee uh), also called SVT, is a very fast heart rhythm that does not follow the regular pathway from the atria to the ventricles. It can cause a heart to beat at rates of 180 to 220 beats per minute in children and up to 300 beats per minute in infants. It can happen at any age and may be your child’s only heart problem. SVT can start and stop quickly. It may last for minutes or continue for hours. If it is not treated, the heart’s ability to pump normally is affected. SVT can occur at rest or be triggered by exercise. There are different types of SVT so your pediatric cardiologist will give more detail on which type of SVT your child has. […] Most children with SVT live completely normal lives and have a normal life expectancy. However, it is important to routinely meet with your child’s pediatric cardiologist for continued SVT care.

• #83 Supraventricular tachycardia – Wikipedia

  https://en.wikipedia.org/wiki/Supraventricular_tachycardia

  A normal resting heart rate is 60 to 100 beats per minute. A resting heart rate of more than 100 beats per minute is defined as a tachycardia. During an episode of SVT, the heart beats about 150 to 220 times per minute.[9] […] Atrial fibrillation affects about 25 per 1000 people,[7] paroxysmal supraventricular tachycardia 2.3 per 1000,[6] Wolff-Parkinson-White syndrome 2 per 1000,[8] and atrial flutter 0.8 per 1000.[10] […] Once an acute arrhythmia has been terminated, ongoing treatment may be indicated to prevent recurrence. However, those that have an isolated episode, or infrequent and minimally symptomatic episodes, usually do not warrant treatment other than observation and explanation. […] In general, patients with more frequent or disabling symptoms warrant some form of prevention. A variety of drugs including simple AV nodal blocking agents such as beta blockers and verapamil, as well as antiarrhythmic drugs may be used, usually with good effect, although the adverse effects of these therapies need to be weighed against potential benefits.[24]

• #84 Supraventricular tachycardia – Wikipedia

  https://en.wikipedia.org/wiki/Supraventricular_tachycardia

  Radiofrequency ablation has revolutionized the treatment of tachycardia caused by a re-entrant pathway. This is a low-risk procedure that uses a catheter inside the heart to deliver radiofrequency energy to locate and destroy the abnormal electrical pathways. Ablation has been shown to be highly effective: around 90% in the case of AVNRT. Similar high rates of success are achieved with AVRT and typical atrial flutter.[25] […] This therapy has further improved the treatment options for AVNRT (and other SVTs with pathways close to the AV node), widening the application of curative ablation to young patients with relatively mild but still troublesome symptoms who might not have accepted the risk of requiring a pacemaker.

  Atrial tachycardias (ATs) and impaired ventricular function are thus important and consistent risk factors for SCD in patients with ACHD, of which those with corrected Tetralogy of Fallot, post-atrial switch operation (Mustard or Senning), left heart obstructive lesions and univentricular hearts have the highest risk of SCD (29 % per decade). […] The treatment of CHD imposes certain safety considerations when choosing antiarrhythmic drugs while various cardiac anatomical barriers and required operator expertise should be taken into account when referring patients for catheter ablation. […] The success rates after catheter ablation in patients with ACHD is somewhat lower compared with the general population, with acute and long-term success rates of 80 % and 68 %, respectively, for accessory pathway ablations, and 6676 % and 5053 %, respectively, for MRATs.
