Does quantitative VCG analysis improve the detection of myocardial infarction compared to standard ECG?

Population

210 patients undergoing coronary arteriography and left ventriculography

Intervention

Frank vectorcardiograms (VCG) analyzed by computer techniques

Comparator

Standard electrocardiograms (ECG) analyzed by manual techniques

Outcome

Detection of definite myocardial infarction (MI)surrogate

Quantitative vectorcardiogram analysis is superior to standard electrocardiogram for accurately detecting myocardial infarction and predicting the anatomic distribution of coronary artery disease.
