Aim: In the present study was investigate the comparison of various echo methodologies in assessing Right Ventricular function in the setting of Inferior wall myocardial infarction with and without right ventricular involvement. Right ventricular dysfunction and stunning frequently is of a transient nature, such that estimation of its true incidence is even more difficult. Criteria have been set for to diagnose RVMI; but, even when strictly employed, the criteria lead to underestimation of the true incidence of right ventricular infarction. Materials and Methods: The study is a prospective case control study involved 124 patients. Both male and female patients are selected for the study. There was no age limit in our study population with a first Q wave acute inferior myocardial infarction with or without RVMI. Results: During the study period, 104 patients were evaluated and underwent a complete echo-Doppler examination. Among these patients, 44 had an RVMI, and constituted Group 1, and the remaining 60 patients had an inferior wall myocardial infarction without right ventricular involvement of Group 2. Conclusion: We conclude that Echo-Dopper assessment was significantly differentiating the early diastolic velocity in patients with RVMI and without RVMI. .
