title: [An analysis of ST segment shift in procordial leads in patients with acute inferior myocardiac infarction with and without right ventricular infarction].
abstract: ST segment change in procordial leads was analysed in 58 patients with acute inferior myocardial infarction (IMI). ST segment depression in V2 lead was negatively correlated with ST segment elevation in a VF lead in patients with IMI. ST segment depression in V2 lead was not observed when IMI was accompanied by right ventricular infarction. It indicates that ST segment depression in procordial leads was the reciprocal change of ST segment elevation in inferior leads. The direction and amplitude of ST segment shift in procordial leads may be affected by the presence of right ventricular infarction (RVI). The ratio of ST V2/ST aVF less than 0.5 may suggest a diagnosis of IMI with accompanying RVI.
