Rawal Med J Jan ;40(1):48-51.

Objective: To compare the conduction abnormalities between anterior and inferior myocardial infarction. Methodology: 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 blocker,Lanoxin and Calcium channel blocker (Verapamil,Diltiazem) were excluded from the study. Results: A total of 600 patients were studied. Out of these 309 had acute Anterior Myocardial Infarction and remaining had acute Inferior Myocardial Infarction. The number of male patients were 70%. Mean age was 58.8 years. Conduction abnormalities were demonstrated in 12.16% patients. Amongst patients with Ant MI,3.5% patients developed atrioventricular blocks and 7.1% Intraventricular conduction defects, In inferior MI 11.3% were atrioventricular and 2.4% were Intraventricular conduction defects. There were more intraventricular defects in anterior MI while atrioventricular defects were more common in inferior MI. 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.
