title: Vectorcardiogram in multiple myocardial infarctions--Correlations between vectorcardiographic and angiographic findings.
abstract: To determine the value and limitations of vectorcardiograms (VCGS) for diagnosing multiple myocardial infarctions, correlations between VCG and angiographic findings were analyzed in 307 cases with severe asynergies due to coronary narrowings on left ventriculograms. While the presence of anterioseptal hypokinesis, corresponding to a nontransmural infarction of the anteroseptal wall, lowered the sensitivity of vectorcardiographic diagnosis for inferior and posterior myocardial infarctions, that of inferoposterior hypokinesis did not lower its sensitivity for anterior myocardial infarction. Severe asynergy, corresponding to a transmural infarction, reduced the VCG sensitivity for diagnosing myocardial infarction occurring in the opposite side of the left ventricle.
