Background: Acute myocardial infarction (AMI) is a major cause of death worldwide with arrhythmia being the most common determinant in the post-infarction period. Objective: To study prevalence of cardiac arrhythmia in AMI patients within 48 hours of admission and to correlate between type of arrhythmia with site of myocardial infarction. Materials and Methods: Descriptive analytic study carried out in Medicine Department, RIMS, Imphal over a period of 2 years. Results and Observations: Hundred AMI patients were studied, of which 76% developed arrhythmia. Most common conduction abnormality was ventricular premature complex (VPC; 23%) followed by sinus tachycardia (21%). Heart block was present in 15%, bundle branch block in 11%, and ventricular tachycardia in 7% of the patients. In inferior wall myocardial infarction (IWMI), sinus bradycardia was more common, so also was heart block more common showing 28.95% against 6.55% in anterior wall myocardial infarction (AWMI). On the other hand, AWMI patients had sinus tachycardia more frequently than IWMI (31% versus 7.8%) and ventricular tachycardia likewise was also more common in them. It was associated with high mortality, six of seven patients who developed ventricular tachycardia died within 48 hours of hospitalization (P-value <0.01). Conclusion: Arrhythmia is common in post-infarction period seen in 76% of AMI patients. It is also a major cause of mortality in them with higher mortality seen in those with later hospital presentation.
