The effect of obesity on electrocardiographic detection of hypertensive left ventricular hypertrophy: recalibration against cardiac magnetic resonance

128 consecutive patients with arterial hypertension referred for CMR from a tertiary hypertension clinic, mean age 51.0 years, 49% male, 51% obese. Excluded: concomitant cardiac pathology confounding hypertrophic response (moderate-severe valvular heart disease, prior MI, cardiomyopathy).

12-lead electrocardiogram (ECG) evaluation using six criteria for left ventricular hypertrophy (Sokolow-Lyon voltage, Sokolow-Lyon product, Cornell voltage, Cornell product, Gubner-Ungerleider voltage, Romhilt-Estes score)

Cardiac magnetic resonance (CMR) at 1.5 T (gold standard reference for left ventricular mass and hypertrophy)
