[Vectorcardiographic and chronotopocardiographic study of septal hypoperfusion].

The study has been carried out in 73 patients (63 men and 10 women), aged between 22 and 59 years, suffering from angina pectoris. The localization in space of the extremities of the initial QRS vectors (10 and 20 ms) is an indicator which is relatively very sensitive to the disturbance in the myocardial irrigation in the regions around the septum and the adjacent ventricular wall. A good relationship has been found namely with the data obtained with thallium scintigraphy after effort. The sensitivity of the vectocardiographic method, like that of dipolar chronotopocardiography, was clearly superior to that of scalar graphs.
