Abstract              Background: In most of the patients during acute myocardial infarction cardiac rhythm disturbances occurs, approximately twenty-five percent have cardiac conduction disturbance within 24 hours following infarct onset. Aim: To study the association of various arrhythmias following acute myocardial infarction within one week with risk factors. Material and Methods: A total of 100 cases of acute myocardial infarction on clinical, electro cardio graphical and biochemical analysis presented to tertiary care hospital were studied over a period of 2 years. ECG was done and types of arrhythmias were noted. Results: Sinus tachycardia (21.05%) was the most common arrhythmia. In patients with DM and hypertension, 93.33% had an arrhythmia. Majority of mortality (33.33%) found in same group DM with hypertension. In patients having hypertension and no DM, 78.04% develops anarrhythmia. 88.46% of smoker patients had arrhythmia; it was found statistically significant. 87.18% alcoholic patients had arrhythmia; it was found statistically significant. 80% of patients with tobacco chewer had arrhythmia; it wasn’t found statistically significant. Conclusion: Age, sex, addiction and other co-morbid conditions like hypertension, diabetes mellitus and addictions like smoking and alcohol are an important predictor of arrhythmia.
