[Cardiogoniometry in coronary heart disease. A clinical study]

Maximal vectors of depolarization (QRS) and repolarization (ST/T), and the initial QRS-vector of CGM, were measured simultaneously with conventional ECG at rest and during exercise in a population of 85 patients with suspected coronary artery disease (CAD). Coronary angiography served as standard, luminal narrowing of at least 50% in a proximal segment of one or more major coronary arteries being taken to define CAD. CGM showed sensitivity of 0.89 and specificity of 0.64 (vs 0.76 and 0.18 for conventional stress ECG).
