Atrial fibrillation
TIC has been associated with supraventricular tachycardia (SVT), ventricular tachycardia (VT), frequent premature ventricular contractions (PVCs), rapid atrial and ventricular pacing, and left bundle branch block. 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. Atrial fibrillation is the most common and well-studied etiology of TIC.
