Tachycardia, supraventricular; AV re-entrant arrhythmia; Narrow complex tachycardia; Narrow QRS complex tachycardia; Narrow QRS tachycardia; Supra Ventricular Tachyardia; Orthodromic AVRT; Antidromic AVRT; Sinoatrial node reentrant tachycardia; Circus movement tachycardia; Junctional reciprocating tachycardia; Persistent junctional reciprocating tachycardia; Supraventricular takycardia; Supraventricular arrhythmia
Supraventricular tachycardia (SVT) is an umbrella term for fast heart rhythms arising from the upper part of the heart. This is in contrast to the other group of fast heart rhythms – ventricular tachycardia, which start within the lower chambers of the heart.
