Right chest leads, V3R-V7R were recorded in 109 persons (40 women, 69 men, mean age 41 years) without evidence of heart disease. An rS or rSr' configuration was found in V3R in 98% and in V4R in 91%. Secondary r waves increased in amplitude and frequency in lateral leads and were found in V7R in 65%. The r or r' waves did not exceed 5 mm in amplitude in any lead. A qS configuration was found most frequently in V6R (16%) but none had qS configuration in all leads. An r/s ratio greater than one was found in eight persons, but the ratio never exceeded 1.5. Measurements of r and S wave amplitudes and ST-segment deviations in V4R in a 45 degree sitting position including deep inspiration and expiration did not change the amplitudes significantly. Normal values for QRS-amplitudes and q-duration, J-point and ST-segment measured 40 msec and 80 msec after the last QRS-deflection are presented.
对109名无心脏病证据的人（40名女性，69名男性，平均年龄41岁）记录了右胸导联V3R - V7R。98%的人V3R导联出现rS或rSr'图形，91%的人V4R导联出现该图形。继发r波在侧胸导联的振幅和频率增加，65%的人V7R导联出现继发r波。各导联r或r'波振幅均未超过5mm。V6R导联最常出现qS图形（16%），但所有人均未在所有导联出现qS图形。8人r/s比值大于1，但该比值从未超过1.5。在45度坐位包括深吸气和呼气时测量V4R导联的r波和S波振幅以及ST段偏移，振幅无明显变化。给出了最后一次QRS波群偏转后40毫秒和80毫秒测量的QRS波振幅、q波时限、J点和ST段的正常值。
