篢his paper reports the data of synchrony 12-leads ECG recorded in 504 healthyadults. Results: ①The values of QTd, QTcd,QRSd, QTpd, OQTd were 48±13, 51±14, 30±11, 43±16, 18±6(ms) in male and 42±12, 47±14, 28±10, 39±17, 16±6 (ms) in female respectively. ②Gender differences: The QTd, QTcd,QRSd, OQTd and QRS, RR intervals of male werelonger than those of female, but the QT, QTc,QTp intervals of male were shorter than those of female.③The reproducibility of QT interval and QTdvalue was affected by the way of measurement, especially by the definition of the end of the T wave.
