Figure 2: (a) Electrocardiogram showing narrow QRS tachycardia at 214/min. The long PR interval, 1:1 atrioventricular conduction and inverted P waves in leads II, III, and aVF consistent with permanent junctional reciprocating tachycardia are to be noted. (b) Electrocardiogram showing termination of tachycardia with a P-wave transiently and recurred with a sinus beat without prolongation of PR interval
