Key result
ECG voltage showed a significant but not close correlation with angiocardiographic left ventricular mass, with 68% and 67% of 75 patients with anatomic hypertrophy meeting Sokolow and Grant criteria.
Why the study?
Does the standard 12-lead electrocardiogram accurately correlate with left ventricular mass and volume determined by quantitative angiocardiography in adult patients?
Population
112 adult patients with normal left ventricles or various degrees of left ventricular dilatation or…

ECG voltage criteria may miss anatomic LVH; leaves open the accuracy of ECG for LV mass estimation.

Does the standard 12-lead electrocardiogram accurately correlate with left ventricular mass and volume determined by quantitative angiocardiography in adult patients?
Standard ECG voltage criteria have a significant but limited correlation with true left ventricular mass, identifying anatomic hypertrophy in only about two-thirds of affected patients.
Baxley et al. (1968) conducted an observational in Left ventricular hypertrophy or dilatation (n=112). Standard 12-lead electrocardiogram vs. Quantitative angiocardiography was evaluated on Correlation between left ventricular mass and ECG voltage. ECG voltage showed a significant but not close correlation with angiocardiographic left ventricular mass, with 68% and 67% of 75 patients with anatomic hypertrophy meeting Sokolow and Grant criteria.
