Normal mean value of measurements of precordial QRS complex in normal subjects

Normal mean value of measurements of precordial QRS complex in normal subjects

Rev Argentina Cardiol 12(1): 26-37

In 100 normal persons a study was made of the mean value and the standard deviation of the QRS duration and of the voltage of its waves in precordial leads CF1 to CF6: the greatest mean value of QRS duration was 0.088 sec. in lead CF2, the normal range being from 0.078 [long dash] 0.098 sec.; the greatest mean value of Q occurred in CF5 (1.3 mm.), the normal range being from 0.1[long dash]2.5 mm.; the greatest mean value of R (12 mm.) also occurred in lead CF5 with normal limits between 6 and 18 mm.; S had its greatest mean value in CF2 (20.9 mm.), the normal values ranging from 15.8 [long dash] 26 mm. In all cases the normal values were calculated on the basis of the mean value and the standard deviation. The wide variations of the latter are discussed.
