Vectorcardiography (VCG) is a part of electrocardiography (ECG). The vectorcardiogram displays the various complexes of the electrocardiogram, i.e. QRS, P and T complexes, in the form of "loops" which are determined from vectors representing successive instantaneous mean electric forces from the heart throughout an entire cardiac cycle. Since the heart is a three-dimensional structure, the elec...

Standard limb leads and unipolar electrocardiography can provide valuable information in the diagnosis of myocardial infarction but there are occasions when the cardiographic changes are inconclusive. It may be difficult to differentiate between pericarditis and myocardial infarction. The electrocardiographic changes in posterior or lateral infarction are not always characteristic. It is not al...

conclusions cgm is a non-invasive technique recently developed for quantitative three-dimensional vectorial analysis of myocardial activity and detection of ischemia and infarction. this technique is clearly more sensitive and more specific than a standard resting 12-lead ecg. results the coronary angiography showed a normal coronary artery in 263 patients (67.4%). a median of cgm score was 1 (...
