However, it was recently reported that the R-wave voltage in lead aVL (RaVL) was as good as other more complicated and time-consuming 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 (ECHO-LVH) could be translated to the general population, a more realistic assessment of its utility in a nonreferral setting. 682 participants (43.5 % males), aged between 27 and 72 years from the urban population of Vitoria, ES, Brazil, were enrolled. We investigated the association of ECHO-LVH (LV mass > 51 g/Ht(2.7)) with several ECG voltage measurements: Sokolow-Lyon and Cornel criteria, S-wave voltage in lead V3 (SV3) and RaVL. The RaVL showed the best positive correlation with LV mass indexed to Ht(2.7), 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 ECHO-LVH. SV3 was not correlated with LV mass. Thus, it seems that most of Cornell's performance depends on its simplified version, that is, RaVL. We have shown that the simple and single assessment of RaVL presented a greater diagnostic ability in detecting ECHO-LVH in the general population, signaling its value mainly as a screening tool.engrestrictedAccessEchocardiographyElectrocardiographyLeft ventricular hypertrophyjoint-national-committeehigh-blood-pressureelectrocardiographic detectionarterial-hypertension7th reportbody-sizediagnosiscriteriaimpactriskarticleCopyright SPRINGER HEIDELBERG10.1007/s00392-013-0578-xCardiac & Cardiovascular Systems
