Diagnostic performance of electrocardiographic criteria for left ventricular hypertrophy among various body mass index groups compared to diagnosis by cardiac magnetic resonance imaging.

ABSTRACT:

Background

Presence of left ventricular hypertrophy (LVH) increases the risk for cardiovascular event. Many electrocardiographic (ECG) criteria can be used to diagnose LVH; however, high body mass index (BMI) may reduce ECG amplitudes.The aim of this study was to investigate the diagnostic performance of ECG criteria for diagnosing LVH among various BMI groups compared to diagnosis by cardiac magnetic resonance (CMR) imaging.

Methods

Patients who were referred for CMR were enrolled. CMR and ECG were performed on the same day. Left ventricular function, volume, and mass were calculated from CMR. Standard ECG criteria were measured, including: Cornell voltage, Cornell product, Romhilt-Estes point score system, Sokolow-Lyon index, and Sokolow-Lyon-Rappaport index. Diagnostic pe
