Key result
Electrocardiographic cut-off values of 4.5 mm for RaVL and 15.5 mm for the Cornell voltage index predicted left ventricular hypertrophy in men with sensitivities of 71% and 74%, respectively.
Why the study?
Additional sensitive and specific electrocardiographic criteria were needed for the early diagnosis of left ventricular hypertrophy.
What are the optimal cut-off values for ECG indices (RaVL and Cornell voltage) to diagnose left ventricular hypertrophy in men compared to echocardiography?
Cross-Sectional (n=184)
What are the optimal cut-off values for ECG indices (RaVL and Cornell voltage) to diagnose left ventricular hypertrophy in men compared to echocardiography?
Effect estimate: AUC 0.744
Lowered cut-offs for RaVL (4.5 mm) and Cornell voltage index (15.5 mm) improve the sensitivity of ECG for detecting left ventricular hypertrophy in men, guiding targeted echocardiography.
New ECG criteria for early LVH detection require prospective validation; leaves open added diagnostic value over standard indices.

Baidina et al. (2022) conducted a cross-sectional in Left ventricular hypertrophy (n=184). Electrocardiographic criteria (RaVL and Cornell voltage index) vs. Echocardiography was evaluated on Diagnosis of left ventricular hypertrophy (AUC 0.744). Electrocardiographic cut-off values of 4.5 mm for RaVL and 15.5 mm for the Cornell voltage index predicted left ventricular hypertrophy in men with sensitivities of 71% and 74%, respectively.
