Abstract
Paroxysmal supraventricular tachycardia is a term that refers to a subset of supraventricular tachycardias characterized by sudden abrupt onset and termination. This group consists of atrioventricular nodal reentry tachycardia, atrioventricular reciprocating tachycardia, atrial tachycardia, and junctional ectopic tachycardia. This chapter will focus on the differentiation of these four tachycardias using electrocardiographic features and intracardiac tracings. Ultimately, the diagnosis of the tachycardia mechanism relies upon three key elements: (1) baseline observations during sinus rhythm, (2) tachycardia features, and (3) the tachycardia response to atrial and ventricular pacing maneuvers.
