ABSTRACT
Unipolar registration of the atrial complex from the proximal part of the right atrium (RA-P wave) has been performed in 32 normal subjects, in 26 patients with valvular, 35 with coronary and seven with hypertensive heart disease, in 52 patients with chronic pulmonary disease and in 26 with miscellaneous heart diseases. In normal individuals a uniform morphology and relatively narrow limits of voltage and width of the RA-P wave were found-for clinical purposes it was convenient to regard values of 0.7–1.6 mV and 80–110 msec as normal. In patients with valvular heart disease the RA-P wave was generally found to be broad and of small voltage, often with secondary spikes and notches. In patients with coronary heart disease low mean voltage, but normal mean width were found. On the other hand, increased mean P voltage and normal width were found in patients with chronic pulmonary disease. The highest mean voltage occurred in patients with chronic cor pulmonale. The variables of the P wave in standard and right atrial (RA) leads were tested for statistical differences between normal individuals and different diagnostic groups of patients. By combinations of variables the discriminant function utilizing the P wave amplitude and width in the RA lead was found to give the better separation between patients with left heart disease and chronic pulmonary disease. Increased P amplitude was found in 10 of 12 patients with isolated pulmonary hypertension, but in none of the 16 patients with secondary pulmonary hypertension.
