Vectorcardiographic criteria for diagnosis of high lateral infarction. Supplement for Chou's criteria.

Vectorcardiographic criteria for the diagnosis of anterior myocardial infarction.

Frank lead vectorcardiograms (VCG) from four carefully selected patient subgroups (226 patients) were analyzed to develop optimal criteria for the diagnosis of anterior myocardial infarction. Specificity was evaluated using 100 healthy volunteers under age 30 and 80 patients with normal left ventriculogram and normal coronary arteriograms. Sensitivity was determined using 25 patients with evolu...

Vectorcardiographic criteria for the diagnosis of inferior myocardial infarction.

Vectorcardiograms (VCG) from two patient groups were analyzed to develop and test quantitative criteria for the diagnosis of inferior myocardial infarction. The first group (219 patients) consisted of four subgroups and was used to develop the criteria. Patients were placed in the normal and infarct subgroups by clinical descriptors including history, course in the coronary care unit, and cardi...

Correlation of vectorcardiographic criteria for myocardial infarction with autopsy findings.

Evaluation of Vectorcardiographic Criteria

Vectorcardiograms (VCG) from a consecutive group of 77 patients with significant aortic valve disease were analyzed. All of the patients had complete left and right heart catheterization with normal coronary arteriograms and normal left ventricular contraction. Thirty-five (46%) patients met VCG criteria for anterior myocardial infarction (AMI-35%) and/or inferior myocardial infarction (IMI-14%...

Evaluation of vectorcardiographic criteria for the diagnosis of myocardial infarction in the presence of left ventricular hypertrophy.

Vectorcardiograms (VCG) from a consecutive group of 77 patients with significant aortic valve disease were analyzed. All of the patients had complete left and right heart catheterization with normal coronary arteriograms and normal left ventricular contraction. Thirty-five (46%) patients met VCG criteria for anterior myocardial infarction (AMI-35%) and/or inferior myocardial infarction (IMI-14%...
