Key result
Araoye criteria show no diagnostic benefit over Sokolow-Lyon for detecting left ventricular hypertrophy.
Why the study?
Various ECG criteria for LVH perform poorly in black subjects compared to white subjects, and Araoye's code system for ECG diagnosis of LVH in blacks has not been validated.
Does Araoye's code system improve the electrocardiographic diagnosis of left ventricular hypertrophy compared to standard criteria in Nigerian hypertensive patients?
Population
100 hypertensive Nigerian subjects and 60 controls
Comparison
Araoye's code system vs Sokolow-Lyon, Cornell voltage, and Romhilt-Estes ECG criteria
Design
Cross-sectional study with ECG and echocardiogram assessments

No advantage supports retaining Sokolow-Lyon; leaves open prospective validation of combined criteria in African cohorts.
Cross-Sectional (n=160)
Does Araoye's code system improve the electrocardiographic diagnosis of left ventricular hypertrophy compared to standard criteria in Nigerian hypertensive patients?
Absolute Event Rate: 71.4% vs 65.7%
Araoye's code system for ECG diagnosis of LVH offers no comparative advantage over Sokolow-Lyon's criteria in Nigerian hypertensives, though a higher number of positive codes identifies more severe LVH.
Dada et al. (2007) conducted a cross-sectional in Hypertension (n=160). Araoye's criteria vs. Standard electrocardiographic criteria (Sokolow-Lyon, Cornell, Romhilt-Estes) was evaluated on Sensitivity for identifying echocardiographic left ventricular hypertrophy. Araoye's criteria for diagnosing left ventricular hypertrophy (sensitivity 71.4%, specificity 74.4%) did not differ significantly from Sokolow-Lyon criteria.
