Background and objectives: Acute right ventricular myocardial infarction

complicates inferior wall myocardial infarction with an incidence of 14–84%.

ECG is the cornerstone in diagnosis as it is cost effective and done easily.

Hence we aimed to study right ventricular infarction in acute inferior wall

myocardial infarction using right precordial leads.

Methods: Present study is based on the analysis of 100 patients admitted to

AMC and ICCU of the Gandhi General Hospital during January 2014 to

September 2015, with acute inferior wall MI. 12 lead ECG with thorough

physical examination was done along with right precordial mapping. ST > or

=1mm in any one RPL was diagnostic of RVI.

Results: A total of 31% patients showed RVI. 32.26% of patients of RVI

presented with adycardia, 9.68% Kussumaul�s sign, 16.13% with complete

heart block. Mortality in RVI was 10 times higher than without RVI(2.77%).

Interpretation and conclusion: Clinical signs and symptomatology are

not fully diagnostic of RVI in inferior wall acute MI. ECG can diagnose (using

right precordial mapping) this condition very early. Early diagnosis will help in

careful monitoring and management of such cases.
