INDICE DE SOKOLOW LYON PDF

Arterial hypertension is a common disease with high prevalence in the general population. Left ventricular hypertrophy LVH is an independent risk factor in arterial hypertension. We assessed the diagnostic performance of the SLI in a cohort of a large general population. To assess the impact of the body-mass-index BMI , we performed interaction analyses. The relations were strongest when obese subjects were taken into account.

The QRS voltage increases with both thickening of the wall pressure overload and dilatation of the chamber volume overload of the left ventricle. ECG detection of left ventricular hypertrophy: the simpler, the better? RaVL is a limb voltage, well aligned with the depolarization axis of the left ventricle. These features probably result from the fact that RaVL does not require thoracic leads, which is undoubtedly a source of variability, particularly in women.

The second interesting feature of RaVL is its univocal threshold at 1. This cut-off was observed independent of sex, body mass index, previous myocardial infarction, ethnicity and conduction disorder. The grey zone, between 0. This lower threshold was associated with a better sensitivity but a lower specificity.

In , Verdecchia et al. The optimal prognostic threshold was defined at 5. With an optimal threshold of 4. RaVL was independently associated with cardiovascular and all-cause mortality, with optimal cut-offs at 6. After excluding, in turn, patients with a positive Sokolow-Lyon index, Cornell voltage or Cornell product, the results remained statistically significant, meaning that RaVL was still able to pick up high-risk patients when other classical and more sophisticated indices failed.

Between these two cut-offs, physicians probably need additional imaging methods to correctly stratify the risk of the remaining patients. For all these reasons, RaVL should now be the first index used to detect LVH during the initial work-up of hypertensive patients; it should replace the very popular but useless Sokolow index, and it is our role to promote RaVL among the medical community and the medical students.

Left ventricular hypertrophy LVH is thickening of the heart muscle of the left ventricle of the heart , that is, left-sided ventricular hypertrophy. While ventricular hypertrophy occurs naturally as a reaction to aerobic exercise and strength training , it is most frequently referred to as a pathological reaction to cardiovascular disease , or high blood pressure. While LVH itself is not a disease, it is usually a marker for disease involving the heart. Causes of increased afterload that can cause LVH include aortic stenosis , aortic insufficiency and hypertension. Primary disease of the muscle of the heart that cause LVH are known as hypertrophic cardiomyopathies , which can lead into heart failure.
