Why the study?
Do electrocardiographic and vectorcardiographic voltage parameters accurately diagnose left ventricular hypertrophy when compared to echocardiography in cardiac patients and normal subjects?
Population
131 subjects, consisting of 80 cardiac patients and 51 normal subjects.
Comparison
Quantitative analysis of electrocardiograms and… vs Echocardiographic observations.
Design
Cross-sectional

No ECG voltage parameter outperforms others for LVH diagnosis; leaves open whether non-voltage criteria improve accuracy in prospective studies.
Do electrocardiographic and vectorcardiographic voltage parameters accurately diagnose left ventricular hypertrophy when compared to echocardiography in cardiac patients and normal subjects?
Standard ECG voltage criteria for left ventricular hypertrophy correlate with LV mass but lack individual diagnostic superiority, indicating that additional non-voltage parameters are needed for accurate diagnosis.
