Abstract—ECG criteria for left ventricular hypertrophy (LVH) were mostly validated using left ventricular mass (LVM) as measured by M-mode echocardiography. LVM as measured by cardiac MRI has been demonstrated to be much more accurate and reproducible. We reevaluated the sensitivity and specificity of 4 ECG criteria of LVH against LVM as ...

Currently accepted LVH ECG criteria such as Cornell voltage and Sokolow-Lyon were used for comparison. The validation cohort consisted of 122 consecutive patients referred for an echocardiogram regardless of the admitting diagnosis. RESULTS The S D was the most accurate single lead measurement for the diagnosis of LVH (AUC: 0.80; p < 0.001).

3.2 | Sensitivity and specificity of the ECG criteria for LVH The most frequent positive criteria were the Cornell Voltage crite‐ ria (35 patients, 36.8%) and the Sokolow‐Lyon index (26 patients, 27.4%). The ECG parameters had a low sensitivity, which ranged from 6% to …

Cardiac Stress Testing: Choosing the Right Test and When
- Non-diagnostic with abnormal baseline ECG: - LBBB, paced rhythm, LVH, ST-segment depressions 0.5 mm - Lower sensitivity and specificity than imaging - Non-localizing (unless ST segment elevations) Indications - Best in patients at intermediate risk for CAD - Normal resting ECG (including RBBB)

quality of a test to diagnose true cases. Specificity (%) was calculated by dividing true negatives by the sum of true negatives and false positives, then multiplying the quotient by 100. Specificity is the quality of a screening test to identify healthy cases. Cases diagnosed as LVH on both ECG and echocardiography were labeled as True Positive.
