Objective. This study was designed to assess ECG as a tool to indicate left ventricular mass in young healthy males with sedentarylife style.Methods. Standard 12-lead ECGs were obtained from 60 Caucasian male university students aged (mean ± standard deviation)22.4 ± 1.9. SV1, RV5, RV6, RaVL, SV3, RI, SIII and QRS duration (in ms) were measured to calculate 6 commonlyused ECG criteria:

Echocardiography was performed to calculate left ventricular mass (LVM). LVM was indexed tobody surface area. Subjects were divided into subgroups: those with body mass index (BMI) 25, and the rest with BMI ≥ 25.Results. Moderate statistically significant correlation appeared between LVMI and Gubner-Ungerleider Amplitude (r = 0.477,p = 0.019) as well as RaVL (r = 0.355, p = 0.044) in subjects with BMI ≥ 25. Sokolow-Lyon Product showed weak statisticallysignificant correlation to LVMI in subjects with BMI 25 (r = 0.253, p = 0.045). No statistically significant correlationbetween LVMI and other criteria was noticed.Conclusions. Commonly used ECG defined LVH criteria are associated with subjects’ BMI and demonstrate weak (for Sokolow-LyonProduct in subjects with BMI 25) to moderate (for Gubner-Ungerleider Amplitude and RaVL in subjects withBMI ≥ 25) correlation with LVMI thus they do little to reflect LVM.
