Key result
Sokolow-Lyon and Cornell criteria outperform RV6/V5 ratio for identifying LV geometry, reaching ~71% accuracy.
Why the study?
Do various ECG voltage criteria accurately distinguish the type of left ventricular hypertrophy geometry?

Do various ECG voltage criteria accurately distinguish the type of left ventricular hypertrophy geometry?
Sokolow-Lyon and Cornell Voltage criteria offer moderate specificity but limited sensitivity for distinguishing specific types of left ventricular hypertrophy geometry.
ECG criteria show only moderate accuracy for LVH geometry and should not yet change practice; leaves open validation in prospective cohorts.
Different types of left ventricular hypertrophy geometry are associated with different risk of cardiovascular disease. The purpose of this study was to determine the role of various ECG voltages of LVH to distinguish the type of LVH geometry. A cross-sectional study from June to November 2015, 100 patients in Adam Malik Hospital Medan. The result of LVH ECG criteria of Sokolow-Lyon was not met then obtained normal left ventricular geometry with 60% sensitivity, 72.22% specificity, and 71% accuracy. The eccentric type of LVH is obtained when the Cornel Voltage is not met; the sensitivity is 25%, specificity 71.88%, and 55% accuracy. Concentric geometric hypertrophy when the RV6/V5> 1 ratio is satisfied, the sensitivity is 55.56%, specificity 56.36%, and 56% accuracy. The RV6/V5>1 ratio was not met, the concentric geometry type of hypertrophy remodeling was determined with a sensitivity of 55.56%, specificity 49.45%, and 50% accuracy. Conclusions, various LVHECG criteria distinguish the type of LVH geometry. Sokolow-Lyon and Cornel Voltage sensitivity and specificity are better than the RV6/V5 ratio.

Tumbur et al. (2018) conducted a cross-sectional in Left ventricular hypertrophy (n=100). ECG voltage criteria (Sokolow-Lyon, Cornell Voltage, RV6/V5 ratio) was evaluated on Diagnostic accuracy of ECG voltage criteria for distinguishing LVH geometry types. Sokolow-Lyon criteria identified normal LV geometry with 71% accuracy, and Cornell Voltage identified eccentric LVH with 55% accuracy, both outperforming the RV6/V5 ratio.
