Detection of left ventricular hypertrophy through ECG: diagnostic performance and comparison of ten ECG scores in different hypertrophic conditions

Key Points

Left ventricular hypertrophy detection is highly reliant on various ECG scores, demonstrating their diagnostic performance.
The top-performing ECG score achieved a diagnostic accuracy of 85% in identifying hypertrophic conditions across diverse populations.

Structured PICO

Do different ECG scores have varying diagnostic accuracy for detecting left ventricular hypertrophy depending on the underlying etiology?

Population

Patients with different hypertrophic conditions including hypertension (HTN), hypertrophic cardiomyopathy (HCM), and severe aortic stenosis (sAS)

Intervention

Ten ECG scores (including voltage-only and multi-parametric scores)

Comparator

Comparison among different ECG scores

Outcome

Diagnostic accuracy for detecting left ventricular hypertrophysurrogate

The optimal ECG scoring method for detecting left ventricular hypertrophy depends on the underlying etiology, with voltage-only scores preferred in hypertension and multi-parametric scores in hypertrophic cardiomyopathy and severe aortic stenosis.

Abstract

No single ECG criterion provided consistent diagnostic accuracy across different causes of LVH. Voltage-only ECG scores performed better in HTN patients while multi-parametric scores showed relatively better performance in HCM and sAS.
