Self-terminating polymorphous ventricular tachycardia occurring at the peak of myocardial ischemia.
Polymorphous ventricular tachycardia (PVT) is a unique arrhythmia that may occur during or shortly after acute myocardial ischemia. It is believed that the occurrence of PVT at the time of ischemia is due to differences in the shortening time of the myocardial potentials in the different layers of the myocardium, caused by the heterogenic blood supply at that time. We describe a case of a patient who developed two consecutive episodes of PVT, both induced by ventricular premature beats (VPBs) that occurred during the peak of myocardial ischemia as detected by the ST analyzing system while hospitalized in the intensive coronary care unit.
