Left ventricular hypertrophy
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.
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. A recent publication reported a prevalence of
