Key result
Maximum spatial QRS voltage and R wave voltage of leads V5 and V6 in patients without left ventricular hypertrophy were inversely correlated with end-diastolic volume.
Why the study?
How does left ventricular end-diastolic volume relate to QRS voltage on electrocardiogram and vectorcardiogram?
Population
59 patients investigated by single plane ventriculography and coronary arteriography

May reduce ECG LVH sensitivity in dilated ventricles; leaves open whether volume-adjusted criteria improve diagnosis.
Observational (n=59)
How does left ventricular end-diastolic volume relate to QRS voltage on electrocardiogram and vectorcardiogram?
Increased left ventricular volume is inversely correlated with QRS voltage, potentially reducing the sensitivity of ECG criteria for left ventricular hypertrophy in patients with cardiac dilatation.
Talbot et al. (1977) conducted an observational in Left ventricular volume and hypertrophy (n=59). 12-lead electrocardiogram and Frank vectorcardiogram was evaluated on Correlation between left ventricular end-diastolic volumes and QRS voltage. Maximum spatial QRS voltage and R wave voltage of leads V5 and V6 in patients without left ventricular hypertrophy were inversely correlated with end-diastolic volume.
