Key result
Correcting RaVL ECG voltages for body mass index improved the performance (0.733 vs 0.695; P<0.0001) and sensitivity (42.4% vs 30.6%; P<0.0005) for detecting left ventricular hypertrophy.
Why the study?
Does BMI-corrected electrocardiographic voltage criteria improve the detection of left ventricular hypertrophy in individuals of African ancestry?
Cross-Sectional (n=661)

Absolute Event Rate: 0.733% vs 0.695%
p-value: p=< 0.0001
Correcting ECG voltage criteria for BMI improves the sensitivity and overall performance of detecting left ventricular hypertrophy in individuals of African ancestry.
No takes yet. Share an insight, caveat, or question.
BMI-corrected RaVL may enhance ECG LVH detection; leaves open validation and outcomes impact in African ancestry populations.
Robinson et al. (2016) conducted a cross-sectional in Left ventricular hypertrophy (n=661). BMI-corrected ECG voltage criteria vs. Uncorrected ECG voltage criteria was evaluated on Performance for LVH detection (p=< 0.0001). Correcting RaVL ECG voltages for body mass index improved the performance (0.733 vs 0.695; P<0.0001) and sensitivity (42.4% vs 30.6%; P<0.0005) for detecting left ventricular hypertrophy.
