The different types are the following: * Sinus tachycardia may be considered an<unk> , since the sinoatrial node (SAN) is discharging at an abnormally fast rate. * Atrial ectopic tachycardia, in which the focus or foci are in the atria of the heart, is an<unk> . * Atrial fibrillation may be considered an<unk> . * Junctional ectopic tachycardia, in which the focus is in the atrioventricular node (AVN), and * Accelerated idioventricular rhythm, involving a ventricular focus, are also examples. Idioventricular tachycardia is notable because it is the only<unk>  which is not an SVT.
