Abstract
Objective: To compare the conduction abnormalities between anterior and inferior myocardial infarction.
Methodology: This study was conducted from 1st January 2011 to 30th June 2011 in Cardiology Department, Lady Reading Hospital, Peshawar. Patients who presented with acute myocardial infarction were included in the study. Patients having renal failure, hypokalemia, hyperkalemia, history of valve replacement, coronary artery bypass graft and those who were using beta blockers, digoxin or calcium channel blockers were excluded from the study.
Results: Out of of 600 patients, 309 had acute anterior myocardial infarction and remaining had acute inferior myocardial infarction and 70% were male. Mean age was 58.8 +/- 12.5 years. Conduction abnormalities were seen in 12.16% patients. Amongst patients with Ant MI, 3.5% developed atrioventricular blocks and 7.1% intraventricular conduction defects. In inferior MI, 11.3% were atrioventricular and 2.4% were intraventricular conduction defects.
Conclusion: Conduction abnormalities are common findings in acute myocardial infarction. Intraventricular conduction abnormalities are more common in anterior MI and atrioventricular conduction abnormalities are more common in inferior Mi. ( Rawal Med J 201; 40: 48- 51).
