Abstract               Coronary heart disease (CHD) remains the major killer of mankind, even though a lot of developments in the diagnosis, management and prevention of risk factors have taken place. Aim of the study is to study right ventricular involvement with various conduction disturbances occurring in 100 cases of acute inferior wall myocardial infarction with or without right ventricular myocardial infarction. Smoking was the commonest risk factor followed by hypertension, diabetes, hypertension, hyperlipidemia, etc. Chest pain was the commonest form of clinical presentation. Other symptoms like sweating, breathlessness, palpitation, nausea and vomiting were also noted. Right ventricular infarction is a common clinical entity in patients with inferior wall myocardial infarction. Hypotension, rised JVP, Kussmaul’s sign and RV S3/S4 are important diagnostic signs of right ventricular infarction. The patients with RV infarction have high incidence of complications like high degree heart blocks, ventricular arrhythmias, cardiogenic shock and have high in-hospital mortality. Therefore presence of right ventricular infarction is a poor prognostic indicator in patients with acute inferior wall myocardial infarction which needs more attention and intensive therapy.
