Abstract

Two distinct electrocardiographic patterns of ventricular fibrillation (VF) complicating acute myocardial infarction (AMI) were observed in 34 patients during the first 24 hours from initial symptoms. Type 1 (seven patients) was characterized by fast disorganized ventricular activity, small voltage, and no clear identifiable QRS complexes (fine VF). Type 2 (27 patients) was defined as multiform QRS configuration (greater than 300/min) with marked changes in the amplitude (polymorphous VF). Type 1 rhythm was seen mostly during the hyperacute ischemic phase, probably associated with total coronary vessel occlusion; type 2 was observed when Q waves were already present in the electrocardiogram.
