  https://www.altru.org/health-library/conditions/atrial-tachycardia

  Atrial tachycardia is an irregular heartbeat, called an arrhythmia. It’s a type of supraventricular tachycardia. […] During an atrial tachycardia episode, the heart beats more than 100 times a minute. Then it returns to a heart rate of around 60 to 80 beats a minute. An episode may start slowly, or it may start suddenly and quickly. It can cause a pounding or racing heartbeat, lightheadedness, dizziness, and fainting. […] The main symptom of atrial tachycardia is a very fast heartbeat. Typically during atrial tachycardia, the heart beats 150 to 200 times a minute. The fast heartbeat may come and go suddenly, or it can be ongoing. […] Other symptoms of atrial tachycardia may include: Pounding or fluttering feelings in the chest or neck, called palpitations. Chest pain. Fainting or almost fainting. Lightheadedness or dizziness. Shortness of breath. Sweating. Weakness or extreme tiredness. Nausea.

• #2 Atrial tachycardia: Symptoms, causes, treatment, and more

  https://www.medicalnewstoday.com/articles/atrial-tachycardia

  Atrial tachycardia is an arrhythmia with a heart rate greater than 100 beats per minute that originates in the atria, or two upper chambers, of the heart. […] The main symptom of atrial tachycardia is the sensation that the heart is beating much faster than usual. If a person takes their pulse, they may find their heart is beating more than 100 beats per minute. […] Some other symptoms a person might notice include: feeling dizzy, fainting, feeling out of breath or like they cannot get enough air, feeling panicky or anxious, fatigue, pain or discomfort in the chest. […] However, people with atrial tachycardia may be asymptomatic, which means they do not experience any symptoms. […] In many cases, atrial tachycardia is benign, which means it is not harmful. However, it may be a risk factor and also a symptom of certain heart issues, such as cardiomyopathy.

  https://www.ncbi.nlm.nih.gov/books/NBK542235/

  Atrial tachycardia can produce symptoms such as palpitations, lightheadedness, and pre-syncope, which can understandably generate anxiety. It is therefore essential to convey to patients that although atrial tachycardia can be bothersome, it is not a lethal arrhythmia. […] Patients with atrial tachycardia may complain of palpitations or sensations of fast heart rate, lightheadedness, chest pain or pressure, or shortness of breath. Symptom intensity will be related to the rate as well as the patients cardiovascular status. The patient may complain of irregular heart rate if the patients tachycardia is sufficient to produce an intermittent AV block. […] Persistent focal atrial tachycardia can result in cardiomyopathy, which may lead to symptoms of dyspnea with exertion, increased lower extremity edema, and chest pain. Although the clinical course is typically benign, there is some risk of sudden cardiac death. […] Overall prognosis depends on conditions precipitating this arrhythmia. However, if atrial tachycardia persists, it can lead to tachycardia-induced cardiomyopathies over time.

On the other hand, incessant atrial tachycardia can contribute directly to tachycardic cardiomyopathy and reversible heart failure.

• #10 Atrial Tachycardia

  https://www.washingtonhra.com/arrhythmias/atrial-tachycardia.php

  Atrial tachycardia occurs when a portion of the atrial tissue speeds up and overtakes the normal sinus node as the pacemaker site of the heart. The symptoms of atrial tachycardia are similar to other SVTs, with palpitation, lightheadness, dizziness, shortness of breath, reduced exercise capacity, weakness, fatigue, chest discomfort, and sweating episodes. […] Atrial tachycardia, as an isolated rhythm disturbance, is not considered a life-threatening condition. Some patients are able to control their episodes with life-style modification. […] Prolonged episodes (typically man months or years) of continuous atrial tachycardia can be problematic. Atrial tachycardia can cause irreversible changes to the atria, including negative remodeling with atrial enlargement and weakness (myopathy). […] Long-lasting atrial tachycardia with continuously rapid ventricular rates (heart rates typically greater than 100 beats per minute) may cause a tachycardia-induced cardiomyopathy (weakening of ventricular muscle and heart function) and symptoms of congestive heart failure.

  https://www.dermatologyadvisor.com/home/decision-support-in-medicine/cardiology/atrial-tachycardia-diagnosis-and-treatment/

  The clinical presentation of this arrhythmia varies significantly from short, rather sporadic, paroxysmal runs to incessant tachycardia. […] A definitive diagnosis of an atrial tachycardia may be only possible through specific clinical or electrophysiologic features of the arrhythmia requiring electrocardiography and sometimes even intracardiac recordings. […] A rare but potentially fatal presentation is tachycardia induced cardiomyopathy with the constellation of symptoms caused by progressive systolic heart failure including edema, dyspnea on exertion, orthopnea and paroxysmal nocturnal dyspnea with documented depressed left ventricular systolic function in the setting of persistent tachycardia. […] Key symptoms: palpitations, chest discomfort, dyspnea at rest or exertion, dizziness, fatigue, near syncope, rarely syncope or could be asymptomatic.

• #15 Atrial Tachycardia Clinical Presentation: History, Physical Examination

  https://emedicine.medscape.com/article/151456-clinical

  Focal atrial tachycardia is usually episodic or paroxysmal. Typically, atrial tachycardia manifests as a sudden onset of palpitations. Atrial tachycardia due to enhanced automaticity may be nonsustained but repetitive or it may be continuous or sustained, as in reentrant forms of atrial tachycardia. […] Atrial tachycardia may gradually speed up soon after its onset („warm-up” phenomenon) and gradually slows down before termination („cool-off” phenomenon). However, the patient may be unaware of this. In a patient with supraventricular tachycardia (SVT), the presence of warm-up phenomenon on an electrocardiogram (eg, on Holter monitoring) suggests that the SVT is atrial tachycardia. […] If the tachycardic episodes are accompanied by palpitations, patients also may report dyspnea, dizziness, lightheadedness, fatigue, or chest pressure. In patients with frequent or incessant tachycardias, a decline in effort tolerance and symptoms of heart failure may represent early manifestations of tachycardia-induced cardiomyopathy.

• #16 Understanding Paroxysmal Atrial Tachycardia (PAT)

  https://www.healthline.com/health/paroxysmal-atrial-tachycardia

  Paroxysmal atrial tachycardia (PAT) is a form of arrhythmia in which an abnormally fast heartbeat starts and ends abruptly from your hearts upper chambers. […] Symptoms of PAT may start and end abruptly. Symptoms may include: dizziness, fatigue, fainting, anxiety, heart palpitations, shortness of breath (dyspnea), chest pain, lightheadedness, feeling faint (presyncope). […] At very high heart rates, your heart may not have enough time to fill with blood before pumping it out to the rest of the body. This can result in symptoms like lightheadedness, dizziness, and fainting. […] In general, paroxysmal tachycardia is not life threatening. However, if it persists, it can result in life threatening complications such as cardiomyopathy, heart failure, and stroke. […] Treatment for paroxysmal atrial tachycardia may include medications like beta-blockers and calcium channel blockers, cardioversion, and catheter ablation procedures. […] PAT is a condition where you experience episodes of fast, abnormal heartbeats. […] PAT is not a life threatening condition, but the periods of sudden rapid heartbeat may be uncomfortable and scary.

• #17 Focal Atrial Tachycardia (FAT) • LITFL • ECG Library Diagnosis

  https://litfl.com/atrial-tachycardia-ecg-library/

  Focal atrial tachycardia (FAT) is a form of supraventricular tachycardia (SVT) originating from a single ectopic focus within the atria but outside of the sinus node. […] FAT, atrial flutter and multifocal atrial tachycardia (MAT) are all forms of atrial tachycardia. […] Management of the three types varies and thus distinguishing between them is clinically important. […] May be paroxysmal or sustained. […] Sustained atrial tachycardia may rarely be seen and can progress to tachycardia-induced cardiomyopathy.

  https://ssl.adam.com/content.aspx?productid=117&isarticlelink=false&pid=1&gid=000186&site=beaumont.adam.com&login=BEAU5332

  Multifocal atrial tachycardia (MAT) is a rapid heart rate. It occurs when too many signals (electrical impulses) are sent from the upper heart (atria) to the lower heart (ventricles). […] In MAT, many locations in the atria fire signals at the same time. Too many signals lead to a rapid heart rate. It most often ranges from 100 to 130 beats per minute or more in adults. The rapid heart rate may cause the heart to work too hard and not move blood efficiently. If the heartbeat is very fast, there is less time for the heart chamber to fill with blood between beats. Therefore, not enough blood is pumped to the brain and the rest of the body with each contraction. […] Some people may have no symptoms. When symptoms occur, they can include: Chest tightness, Fainting, Lightheadedness, Sensation of feeling the heart is beating irregularly or too fast (palpitations), Shortness of breath, Weight loss and failure to thrive in infants. […] Other symptoms that can occur with this disease: Breathing difficulty when lying down, Dizziness. […] MAT can be controlled if the condition that causes the rapid heartbeat is treated and controlled.

• #19 Atrial Tachycardia: Causes, Symptoms, Diagnosis, and Treatment

  https://angolodeldottorino.it/Eng/Medicine/Cardiology/heart-rhythm-disorders/atrial-tachycardia.php

  Atrial tachycardia is a heart rhythm disorder characterized by an increased heart rate originating from an ectopic atrial focus, distinct from the sinoatrial node. This condition can manifest in a paroxysmal form, with self-limiting episodes, or a persistent form, lasting for prolonged periods. Its clinical relevance depends on the frequency and duration of the episodes, the presence of underlying heart disease, and the ventricular response. […] Clinically, atrial tachycardia may present with varying degrees of severity depending on heart rate, episode duration, and ventricular response. In otherwise healthy individuals, it may be asymptomatic or associated with mild symptoms, whereas in patients with heart disease, it can cause hemodynamic instability. […] The most common symptoms include palpitations, dyspnea, dizziness and presyncope, chest pain, and fatigue and exercise intolerance. In severe cases, atrial tachycardia may contribute to the onset of heart failure, especially if the ventricular response is excessively high and not adequately controlled.

  Lightheadedness may result from relative hypotension, depending on the heart rate and other factors, such as the state of hydration and particularly the presence of structural heart disease. The faster the heart rate, the more likely a patient is to feel lightheaded. A rapid rate and severe hypotension may lead to syncope. […] Reentrant atrial tachycardia is not uncommon in patients with a history of a surgically repaired atrial septal defect. The scar tissue in the atrium may give rise to the formation of a reentrant circuit. […] In patients with multifocal atrial tachycardia (MAT), the history may disclose an underlying illness that is causing the tachycardia. Such illnesses include pulmonary, cardiac, metabolic, and endocrinopathic disorders. […] Chronic obstructive pulmonary disease (COPD) is the most common underlying disease process (60%). The arrhythmia is commonly precipitated by exacerbation of COPD, sometimes due to infection or exacerbation of heart failure. Increasing hypoxemia with respiratory acidosis and advanced disease also leads to increased bronchodilator usage, thereby increasing catecholamine levels, which may contribute to development of MAT.

  Patients may experience palpitations, chest pain, fatigue, shortness of breath, or reduced exercise tolerance. Some patients, even children, with incessant atrial tachycardia may develop tachycardiomyopathy and consequently congestive heart failure. […] In structurally healthy hearts, this arrhythmia usually has a good prognosis. When tachycardia is persistent or incessant, it can lead to myopathy, and consequently to ventricular dilation and a reduction in the ejection fraction. Patients with underlying heart disease or with pneumological concerns generally can tolerate tachycardia less.

  Both can lead to tachycardia-induced cardiomyopathy when incessant over periods of several weeks or months. […] Macro-reentrant atrial tachycardias could resemble typical cavo-tricuspid isthmus dependent atrial flutter and are frequently persistent although they could be paroxysmal as well. […] Atrial tachycardias become more prevalent with age at the expense of a higher representation of macro-reentrant atrial tachycardias in the older population, while focal atrial tachycardias become rather rare. […] Incessant atrial tachycardias may be misinterpreted as sinus tachycardia. When incessant atrial tachycardias are not recognized could progress to the development of tachycardia-induced cardiomyopathy and heart failure. […] After termination of the tachycardia in the acute setting, the patient must be educated regarding the recurrent nature of the arrhythmia, and therapy to prevent recurrence should be considered.

• #23 Paroxysmal Atrial Tachycardia – StatPearls – NCBI Bookshelf

  https://www.ncbi.nlm.nih.gov/books/NBK538317/

  Atrial tachycardia is a form of supraventricular tachycardia (SVT) usually seen in patients with structural heart abnormalities but also seen in patients with structurally normal hearts. […] Heart rates are highly variable in atrial tachycardia producing a rate usually between 100-250. The rhythms of atrial tachycardias are commonly regular, but irregular variants can be seen. […] Patients with atrial tachycardia can be asymptomatic or symptomatic. If asymptomatic, the patients arrhythmia will be found incidentally on an EKG or any rhythm recorder. Patients who present symptomatically may complain of dizziness, palpitations, dyspnea, lightheadedness or chest pain. […] Atrial tachycardia is not considered a life-threatening condition. […] Prolonged states of atrial tachycardia can cause long term effects on the heart such as cardiac remodeling. Atrial tachycardia typically is more difficult to control the more prolonged time the heart stays in the arrhythmia, so it is essential to correct the arrhythmia or underlying issue as quickly as possible.

  The difference between atrial flutter and AFib in terms of feeling is very similar. However, if the person can have someone (or even themselves) feel a pulse if the pulse is regular even though it’s fast, the problem is probably atrial flutter. If the pulse is fast and irregular, then the person is more likely to have AFib. […] Common clinical symptoms of both arrhythmias are: Palpitations (person feels their heart beating or pounding), Fatigue, Shortness of breath, Feeling like you going to faint, Blurry vision, Lightheadedness, Heart skipping beats. […] Serious symptoms may include the following: More severe shortness of breath, Sweating, Chest pain, Fainting or loss of consciousness. […] Patients with atrial flutter may have a slightly better prognosis than patients with atrial fibrillation.

• #37 Atrial Tachycardia | Conditions | UCSF Health

  https://www.ucsfhealth.org/conditions/atrial-tachycardia

  An abnormal heart rhythm is a change in either the speed or the pattern of the heartbeat the heart may beat too slowly, too rapidly or irregularly. […] When the heart beats too quickly, it cannot fill completely so the body doesn’t receive the blood volume it needs to function properly. […] There are several types of abnormal heart rhythms, some occur in one of the atriums and are called atrial, others occur in the ventricles and are called ventricular. […] Depending on the type and severity of your arrhythmia, and the results of various tests including the electrophysiology study, there are several treatment options. […] Certain anti-arrhythmic drugs change the electrical signals in the heart and help prevent abnormal sites from starting irregular or rapid heart rhythms. […] A technique pioneered at UCSF, radiofrequency catheter ablation destroys or disrupts parts of the electrical pathways causing the arrhythmias, providing relief for patients who may not have responded well to medications, or who would rather not or can’t take medications.
