Right chest electrocardiographic patterns in normal subjects.

Abstract:

:Right-sided chest lead ECGs (V3R to V6R) were recorded in 110 normal male subjects who were between the ages of 17 and 22 years old (mean, 17.9 years). The prevalence of the rS pattern decreased from V3R (89 percent) to V6R (37 percent). However, the opposite was the case for the rSr pattern (10 percent in V3R and 36 percent in V6R). The amplitudes of the r wave, S wave and secondary r wave all progressively decreased from V3R to V6R. The prevalence of the qr and qS patterns was 0 and 1 percent, respectively in V3R and 14 and 2 percent, respectively in V6R. A positive ST segment deviation of 0.5 to 1 mm was present in 13 percent of subjects in V3R and 5 percent in V4R. T wave inversion was common and the prevalence increased from V3R (60 percent) to V6R (79 percent).
