Abstract

High frequency electrocardiograms were studied in 19 patients with chronic neumopathies, pulmonary arterial hypertension and respiratory failure in the great majority. Studies were made of: a) the significance of conduction disorders in the right ventricle either at the fasciculary branch or within the mass of the ventricle with regard to the time of appearance and the length of the intrinsicoid deflection and its components. b) The duration of the electrical sistole of each ventricle in relation with hyperatrophy that results in sistolic over loading. c) An attempt was made to correlate the number of high frequency deflections (discontinuity of activity) with the prognosis.
