Why the study?
Does the voltage of the R wave in lead aVL improve cardiovascular risk stratification in hypertensive patients without left ventricular hypertrophy on ECG?
Does the voltage of the R wave in lead aVL improve cardiovascular risk stratification in hypertensive patients without left ventricular hypertrophy on ECG?
The R wave voltage in lead aVL provides independent prognostic value for cardiovascular events in hypertensive patients without ECG evidence of left ventricular hypertrophy.

May support refined risk stratification in hypertension without LVH; leaves open prospective validation before clinical adoption.
Verdecchia et al. (2009) studied this question.
