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).
对110名年龄在17至22岁（平均17.9岁）的正常男性受试者记录了右侧胸导联心电图（V3R至V6R）。rS型的发生率从V3R（89%）降至V6R（37%）。然而，rSr型的情况则相反（V3R为10%，V6R为36%）。r波、S波和继发性r波的振幅均从V3R至V6R逐渐降低。qr型和qS型的发生率在V3R分别为0和1%，在V6R分别为14和2%。V3R有13%的受试者、V4R有5%的受试者出现0.5至1毫米的ST段正向偏移。T波倒置很常见，发生率从V3R（60%）增至V6R（79%）。
