Polymorphous ventricular tachycardia early after acute myocardial infarction

摘要: Abstract Ventricular tachyarrhythmias are a major cause of cardiac death within the early hours an evolving acute myocardial infarction. Diverse cytochemical and metabolic alterations develop in ischemic periischemic zones after coronary artery occlusion subsequent reperfusion. 1,2 These change rapidly over time may various morphologically distinct ventricular arrhythmias different stages 1,3 One type malignant tachyarrhythmia that appears during infarction is polymorphous tachycardia (VT). 3,4 The electrophysiologic mechanism therapy differ from those other forms VT. 5,6 occurrence VT has been infrequently reported, 4 although incidence 1.2 to 2% overall hospitalization for had reported. This report describes clinical electrocardiographic features patients with
