“CLINICAL PROFILE OF BRADYARRHYTHMIA IN ACUTE MYOCARDIAL INFARCTION PATIENTS : A PROSPECTIVE OBSERVATIONAL STUDY”

Abstract

Coronary artery disease, it remains most and important cause of death all over the world. Many of these deaths are attributed to the development of arrhythmias. Arrhythmias are key events before, during or after the occurrence of acute MI. Bradyarrhythmias occur more frequently in inferior than anterior wall myocardial infarction. Sinus bradycardia is the most common bradyarrhythmia throughout acute myocardial infarction, seen frequently in rst 4-6 hours of infarction. Block of early onset is generally of short duration. First degree atrioventricular block has no hemodynamic effects and needs no intervention. Treatment required only if symptoms developed. A prospective observational study Methods conducted at a tertiary care centre with approval from Ethics Committee for Academic Research projects, Postgraduate Academic Committee. A total of 60 patients over a period of 1 year admitted to the ICU for Acute myocardial infarction having bradyarrhythmia are included in study. Results Mean age group is 65 ± 14. All females are of post menopausal age group. Hypertension is the most common risk factor. It is present in (48.33%) patients. Diabetes mellitus is second most common risk factor in present study. It is present in (38.33%) patients. Smoking is present in (26.67%) patients. Total no of anterior wall MI with bradyarrhythmia is (26.67%) while no of inferior wall MI with bradyarrhythmia is (71.67%). In this study, no of cases discharged is (90%) while mortality is seen in (10%) patients. It is also seen that conduction defects are most Conclusion commonly associated with inferior wall myocardial infarction and interventricular defects are commonly associated with anterior wall myocardial infarction patient. Maximum bradyarrhythmia are seen in 1st hour of presentation.
