Overview

ECG should not replace TTE for LVH screening in this population; leaves open utility in hypertensive children.

Study Design

Type

Cross-Sectional (n=313)

Structured PICO

Does ECG accurately detect left ventricular hypertrophy compared to TTE in normotensive African children?

P
Population
313 normotensive children (mean age 7.8 years) in north-Madagascar evaluated for left ventricular hypertrophy using ECG and TTE.
E
Exposure
Electrocardiography (ECG) screening using the Sokolow-Lyon index (>35 mm)
C
Comparator
Transthoracic echocardiography (TTE) measuring left ventricle mass indexed by height or weight
O
Outcome
Diagnostic accuracy (sensitivity, specificity, positive predictive value) of ECG for detecting left ventricular hypertrophy compared to TTEsurrogate

ECG is an inefficient screening tool for detecting left ventricular hypertrophy in normotensive African children, and TTE remains necessary to exclude the condition.

Cite This Study

Gioia et al. (2016) conducted a cross-sectional in Left ventricular hypertrophy (n=313). Electrocardiography (ECG) screening vs. Transthoracic echocardiography (TTE) was evaluated on Detection of left ventricular hypertrophy. ECG screening using the Sokolow-Lyon index showed poor sensitivity (13-16%) and positive predictive value (11-18%) for detecting left ventricular hypertrophy compared to TTE in normotensive children.
