Key result
The most important EKG variables predictive of echocardiographic left ventricular mass are QRS duration, S V1-3, strain T-wave, and lateral voltage, with the Romhilt-Estes score showing r=0.621.

QRS duration, S V1-3, strain T-wave, and lateral voltage are the most important EKG variables predictive of echocardiographic left ventricular hypertrophy.
Kansal et al. (1983) conducted a cross-sectional in Left ventricular hypertrophy (n=89). Electrocardiographic (EKG) criteria vs. Echocardiographic left ventricular mass (LVME) was evaluated on Correlation and sensitivity of EKG criteria with LVME (r = 0.621). The most important EKG variables predictive of echocardiographic left ventricular mass are QRS duration, S V1-3, strain T-wave, and lateral voltage, with the Romhilt-Estes score showing r=0.621.
