Abstract              Background: Acute myocardial infarction (AMI) is a major cause of death worldwide with arrhythmia being the most common determinant in the post-infarction period. Objectives: To evaluate the incidence and profile of cardiac arrhythmias in acute myocardial infarction in the first 48 hours of hospitalization. Material and Methods: 100 consecutive acute myocardial infract patients presenting to intensive care unit of medicine department. Results: Most common (31%) age group was 41-50. 80% subjects reported with arrhythmias in 48 hours post myocardial ischemic attack. Sinus arrhythmias being most common 31.25% and ventricular tachycardia with most fatal among all arrhythmias. Conclusions: Arrhythmias are common causes of mortality immediate post ischemic period, so prompt intervention can prevent both arrhythmias and deaths in acute ischemic attack patients.

Key Words: Acute myocardial infarction, arrhythmias, ventricular tachycardias
