Key result
Electrocardiographic measurements of the S wave in V3, R wave in aVL, and T wave in V1 showed strong independent relations with echocardiographic left ventricular mass (each p<0.001).
Why the study?
The study was conducted to develop improved electrocardiographic criteria for detecting left ventricular hypertrophy.
Observational (n=414)
p-value: p=<0.001
No takes yet. Share an insight, caveat, or question.
May support refined ECG detection of LVH; leaves open randomized confirmation before practice change.
Casale et al. (1985) conducted an observational in Left ventricular hypertrophy (n=414). Electrocardiographic voltage measurements vs. Echocardiographic left ventricular mass was evaluated on Independent relations with left ventricular mass (p=<0.001). Electrocardiographic measurements of the S wave in V3, R wave in aVL, and T wave in V1 showed strong independent relations with echocardiographic left ventricular mass (each p<0.001).
