BACKGROUND ST elevation myocardial infarction is an acute emergency, more than 50% of deaths due to STEMI occur within first 1 hour, mainly due to various arrhythmias. Various arrhythmia can complicate the course of STEMI. This study was done to access the incidence and pattern of arrhythmias complicating STEMI and the prognostic implications of these arrhythmias. MATERIALS AND METHODS 100 patients were included in the study that fulfilled the required criteria. They underwent detailed history taking and systemic examination. Patients were monitored through cardiac monitor and serial ECG recording were taken specially if any rhythm disturbances were observed and data was entered in a pretested proforma. RESULTS Among 100 patients, 60 were male and 40 were female. Commonest arrhythmias noticed in this study were sinus tachycardia (31%), followed by bundle branch block (30%), ventricular arrhythmia (25%) AV blocks (20%) sinus bradycardia (18%), supraventricular arrhythmia (4%) and AIVR in 1%. Mortality was more in patients with ventricular tachycardia and complete heart block. Majority of arrhythmias (76%) occur during first hour of hospitalization. CONCLUSION The commonest arrhythmia encountered were sinus tachycardia followed by bundle branch block (BBB), AV block and sinus bradycardia, AV block and sinus bradycardia were common with IWMI and ventricular arrhythmia and bundle branch block were common with AWMI.
