[Value of the vectorcardiogram in the evaluation of right heart hypertrophy in chronic obstructive lung diseases].

In 41 patients with severe chronic obstructive lung disease vector cardiographic and electrocardiographic results and the level of pulmonary arterial pressure (pap) are compared. We observed a positive correlation between normal results from vector cardiography, electrocardiography, and pulmonary arterial pressure. In cases of hypertrophy of the right heart, type I and type II according the method of Lichtlen, pulmonary arterial hypertension was found in 72% of the cases.
