Nettet19. sep. 2024 · A fast heart rate resulted in an increasing difference between intrinsic and modified QTc. Recently, in the manuscript evaluating the LBBB-formula in RBBB-QRS-complexes, the authors applied three different heart rate correction formulas (Bazett, Fridericia, and Hodges) after QT-correction (due to QRS width) . Nettet1. aug. 2024 · In statistics, the Hodges–Lehmann estimator is a robust and nonparametric estimator of a population's location parameter. For populations that are symmetric about one median, such as the (Gaussian) normal distribution or the Student t -distribution, the Hodges–Lehmann estimator is a consistent and median-unbiased estimate of the …
