title: Right ventricular filling abnormalities in acute inferior wall myocardial infarction--a pulsed Doppler study.
abstract: Pulsed Doppler derived velocity profile of right ventricular filling was used to assess right ventricular diastolic function in 29 patients with acute inferior wall myocardial infarction. The peak velocities of the early filling wave 'E' and the atrial wave 'A' were measured. Diastolic dysfunction, defined as E/A ratio less than 1.0, was seen in 15 patients. Of these 15 patients, 9 had electrocardiographic evidence of right ventricular infarction and only 6 had clinical evidence of right ventricular failure. None of the 14 patients without right ventricular diastolic dysfunction (E/A ratio more than 1.0) had electrocardiographic evidence of right ventricular infarction or clinical evidence of right ventricular failure. Pulsed Doppler appears to be a sensitive technique in identifying hemodynamic derangements induced by right ventricular infarction.
