Vectorcardiography may boost RVH detection sensitivity versus ECG; hypothesis-generating and should not yet change practice.
Do simple quantitative vectorcardiographic criteria improve the sensitivity of diagnosing right ventricular hypertrophy compared to conventional electrocardiogram in patients with conditions predisposing to RVH?
Simple quantitative vectorcardiographic criteria based on QRS loop area distribution may provide a more sensitive means for diagnosing right ventricular hypertrophy than conventional electrocardiography.
