Abstract
According to hypertension guidelines the recommended electrocardiographic ECG diagnostic criteria for left ventricular hypertrophy LVH are the Sokolow–Lyon and Cornel voltage criteria both with general acceptance by primary care physicians However it was recently reported that the Rwave voltage in lead aVL RaVL was as good as other more complicated and timeconsuming ECG criteria to detect LVH in hypertensive patients Therefore our aim was to investigate if the ability of the RaVL to identify echocardiographic left ventricular hypertrophy ECHOLVH could be translated to the general population a more realistic assessment of its utility in a nonreferral setting682 participants 435 males aged between 27 and 72 years from the urban population of Vitoria ES Brazil were enrolled We investigated the association of ECHOLVH LV mass 51 g/Ht27 with several ECG voltage measurements Sokolow–Lyon and Cornel criteria Swave voltage in lead V3 SV3 and RaVLThe RaVL showed the best positive correlation with LV mass indexed to Ht27 superior to both Cornell and Sokolow–Lyon criteria and was not influenced by gender Analysis of the ROC curves showed that the RaVL depicted a significant superior performance in relation to all the other measurements in the ability to detect ECHOLVH SV3 was not correlated with LV mass Thus it seems that most of Cornell’s performance depends on its simplified version that is RaVL
