title: [Changes in the electro- and vectorcardiograms in primary vascular pulmonary hypertension].
abstract: A progressive elevation of the blood pressure in the pulmonary circulation in patients with primary vascular pulmonary hypertension results in isolated hypertrophy of the right-ventricle. According to electro- and vectorcardiographic data of the McFee--Parungao system, a significant predominance of the right vetricular potentials is noted, distinct reorientattion observed in those sections of the vectors that may reflect the process of hypertrophy and dilatation of the outflow tracts of the right ventricle.
