    Abstract:
    The relationship between ST segment elevation on the right precordial lead V4R and the hemodynamic, echocardiographic, and myocardial scintigrapic signs suggestive of right ventricular (RV) infarction was studied in 42 patients with acute inferior myocardial infarction. Twenty-two patients had ST segment elevation in V4R. Among these patients, a significant correlation was demonstrated between V4R ST segment elevation and the hemodynamic (p less than 0.001), scintigraphic (p less than 0.001), and echographic (p less than 0.02) criteria for acute RV infarction. These results support the validity of this new electrocardiographic sign as a practical means in aiding the clinical detection of RV involvement with acute transmural inferior myocardial infarction.
