Echocardiographic LV mass method compared with ECG voltages; leaves open diagnostic utility in enlargement.
Does left ventricular mass determined by echocardiography correlate with vectorcardiographic and electrocardiographic voltage measurements in patients with left ventricular enlargement and normal subjects?
This study describes a method for calculating left ventricular mass using echocardiography and compares it to electrocardiographic and vectorcardiographic voltage measurements.
Bennett et al. (1974) studied this question.
