title: Simultaneous AV nodal reentrant and ventricular tachycardias.
abstract: Simultaneous AV nodal reentrant and ventricular tachycardias were observed during the course of an electrophysiological study in a 51-year-old patient who suffered from recurrent attacks of sustained ventricular tachycardia. Occurrence of simultaneous tachycardias was facilitated by the fact that both tachycardias had a similar cycle length. Ventricular tachycardia was most probably initiated by AV nodal tachycardia previously induced by atrial extrastimulation following the administration of atropine.
