The proposed ECG criteria for the diagnosis of left ventricular hypertrophy improved the sensitivity and overall accuracy of the test.
Cohort (n=94)
Do the proposed ECG criteria improve the sensitivity and overall accuracy for diagnosing left ventricular hypertrophy compared to current criteria?
A new ECG criterion based on the deepest S wave improves the sensitivity and accuracy of diagnosing left ventricular hypertrophy.
BACKGROUND: Current electrocardiographic (ECG) criteria for the diagnosis of left ventricular hypertrophy (LVH) have low sensitivity. OBJECTIVES: The goal of this study was to test a new method to improve the diagnostic performance of the electrocardiogram. METHODS: The study was divided into 2 groups, a test and a validation cohort. In the test cohort, 94 patients were analyzed, including 47 with the diagnosis of hypertensive crisis and 47 with normal blood pressure at admission. Echocardiography was used to estimate the left ventricular mass index. Area under the curve (AUC) analysis was used for comparison of single and combined leads. The McNemar test was used to assess agreement among the ECG criteria against the left ventricular mass index. The proposed ECG criteria involved measuring the amplitude of the deepest S wave (S RESULTS: The S CONCLUSIONS: The proposed criteria for the ECG diagnosis of LVH improved the sensitivity and overall accuracy of the test.
Peguero et al. (2017) conducted a cohort in Left ventricular hypertrophy (n=94). Proposed ECG criteria vs. Current ECG criteria was evaluated on Sensitivity and overall accuracy. The proposed ECG criteria for the diagnosis of left ventricular hypertrophy improved the sensitivity and overall accuracy of the test.
