Ventricular fibrillation (VF) developed in 7.42% patients with acute myocardial infarction (AMI). It was more frequent among patients with anterior myocardial infarction compared to inferior myocardial infarction.
On the basis of sequence of events, cases of ventricular fibrillation (VF) were classified in to Primary (P), Secondary (S) and Agonal (A).
57.69% cases had SVF, 30.76% had AVF and only 11.53% cases had PVF. In all cases of PVF, ECG was normal prior to the development of VF and developed abruptly without any warning.
