[Interpretation of the ECG atrial P wave].
High + PV1 waves are analyzed in a group of patients with chronic ischemic heart disease who had no other ECG signs of right-atrial hypertrophy; they all had more or less pronounced signs of left-atrial affection. Changes in wave P on the ECG of patients with chronic ischemic heart disease and marked circulatory insufficiency, rheumatic mitral stenosis, cor pulmonale and in healthy individuals were compared. It is concluded that a high + PV1 wave on the ECG in the absence of other ECG signs of right-atrial hypertrophy reflects delayed conduction in the left atrium.
