Does electrocardiogram using various voltage criteria accurately detect left ventricular hypertrophy compared to echocardiogram in pediatric patients with aortic valve disease?
This study aims to evaluate the diagnostic accuracy of ECG voltage criteria for detecting left ventricular hypertrophy in pediatric patients with aortic valve disease, potentially offering a more accessible alternative to echocardiography.

ECG voltage criteria for pediatric LVH in aortic valve disease remain unvalidated; leaves open clinical utility pending higher-level evidence.
Background: Left ventricular hypertrophy (LVH) is a pathological remodeling of myocardial tissue occurring in response to an increase in cardiac workload. The most significant cause of LVH in the pediatric population is aortic valve disease, which includes aortic valve stenosis and insufficiency. Though LVH can arise naturally in response to strenuous exercise, it has clinical utility as a marker of hypertension and heart disease. LVH can be detected using certain voltage criteria via electrocardiogram (ECG), though this approach typically exhibits poor sensitivity. The current gold standard for LVH identification is echocardiogram -however, waiting times and operator skill are significant variables in echocardiographic diagnosis of LVH. This study evaluates the sensitivity and specificity of various voltage criteria for LVH in this population, and whether amalgamating criteria can boost their accuracy.

Tapas Mondal (2015) conducted an observational in Aortic valve disease with suspected left ventricular hypertrophy (n=61). Combined ECG voltage criteria (Cornell Adult Female and JACC Age-related) vs. Echocardiography (gold standard) was evaluated on Sensitivity and specificity for detecting left ventricular hypertrophy. Combining Cornell Female voltage criteria as a screening tool with JACC pediatric criteria yielded a sensitivity of 88.64% and specificity of 83.33% for detecting left ventricular hypertrophy.
