LEFT VENTRICULAR MASS IN ATHLETES WITH AND WITHOUT ELECTROCAR DIOGRAPHIC LEFT VENTRICULAR HYPERTROPHY / 中国运动医学杂志

ABSTRACT

In order to determine the pathophysiologic significance of electrocardiographic ventricular hypertrophy in athletes (LVH ath), echocardiographic measurements of left ventricular mass (LVM) were performed on 50 LVH ath. and 50 non-LVH matched ath. They were members of National Teams of track and field, swimming, football and cycling, with an average age of 20.74?3.3 years. Anatomic validation of the method was used for calculation of LVM in this study. Comparisons of LVM were made between LVH ath. and non-LVH ath., and between non-LVH ath. and the untrainedLVM=1.04?[(LVID+PWT+IVST)~3-(LVID)~3]-14Results showed no significant difference of LVM between LVH ath. and non-LVH ath. while LVM of non-LVH ath. were considerably greater than that of the untrained (P
