The types of SVT associated with TIC include atrial fibrillation, atrial flutter, incessant atrial tachycardia, permanent junctional reciprocating tachycardia, atrioventricular reciprocating tachycardia, and atrioventricular nodal reentry tachycardia. [1] Atrial fibrillation is the most common and well-studied etiology of TIC. [1] [5]
Atrial fibrillation (AF, AFib or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart. [ 11 ] [ 12 ] It often begins as short periods of abnormal beating , which become longer or continuous over time. [ 4 ]
Atrial tachycardia is a type of heart rhythm problem in which the heart's electrical impulse comes from an ectopic pacemaker (that is, an abnormally located cardiac pacemaker) in the upper chambers of the heart, rather than from the sinoatrial node, the normal origin of the heart's electrical activity.
Atrial fibrillation: Irregular impulses reaching AV node, only some being transmitted. The following types of supraventricular tachycardias are more precisely classified by their specific site of origin. While each belongs to the broad classification of SVT, the specific term/diagnosis is preferred when possible: Sinoatrial origin: [23]
According to ICD-10, hypertensive heart disease (I11), and its subcategories: hypertensive heart disease with heart failure (I11.0) and hypertensive heart disease without heart failure (I11.9) are distinguished from chronic rheumatic heart diseases (I05-I09), other forms of heart disease (I30-I52) and ischemic heart diseases (I20-I25).
Catheter ablation may be recommended for a recurrent or persistent arrhythmia resulting in symptoms or other dysfunction. Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [1] Pulmonary vein isolation by transcatheter ablation can restore sinus ...
Chronic stable heart failure may easily decompensate. This most commonly results from an intercurrent illness (such as pneumonia ), myocardial infarction (a heart attack), abnormal heart rhythms (such as atrial fibrillation ), uncontrolled high blood pressure , or the person's failure to maintain a fluid restriction, diet, or medication.

[2] [5] [10] [11] Patients with noncompliant ventricles and diastolic dysfunction are particularly sensitive to loss of atrial contribution to ventricular filling and have a greater chance of developing the syndrome. This includes patients with cardiomyopathy (hypertensive, hypertrophic, restrictive) and elderly individuals. [5] [7] [10] [12]
