The electrocardiographic manifestations of pectus excavatum before and after surgical correction
2024, Journal of ElectrocardiologyAssociation between electrocardiographic QRS transition zone and mortality from all causes and cardiovascular diseases: A systematic review and meta-analysis
2022, Journal of ElectrocardiologyCitation Excerpt :Previous studies had examined the mechanism of precordial transition. Tahara et al. [19] found that about two thirds of outpatients with CWR and CCWR can be owing to smaller or larger degree of septal angle calculated through cardiac computed tomography. In the remaining cases, factors including vertical heart and left septal fascicular block might account for CWR and CCWR, respectively.
Reappraisal of electrocardiographic criteria for localization of idiopathic outflow region ventricular arrhythmias
2021, Heart RhythmCitation Excerpt :However, uniform attitudinal position of the outflow regions in the chest cavity does not apply for all patients. The relationship between the anatomic and the electrical axes of the heart is complex, as noted in a study that examined cardiac rotation using cardiac computed tomography.27 Subtle differences in the anterior-posterior, left-right, and superior-inferior relationships between the ASVs and the RVOT can affect outflow region VA ECGs.6,16,17,19
Prognostic value of Goldberger's electrocardiographic criteria for left ventricular dysfunction
2021, Journal of ElectrocardiologyCitation Excerpt :This delay in QRS transitioning is manifested as poor R wave progression on ECG. Previous studies have shown that both LVH and dilated cardiomyopathy are associated with clockwise rotation and delayed QRS transitioning [36,37]. Recent studies have also found clockwise rotation of the heart is associated with increased cardiovascular and heart failure mortality [38–40].
Distribution and determinants of QRS rotation of black and white persons in the general population
2018, Journal of ElectrocardiologyCitation Excerpt :The angle of the interventricular septum was postulated in early publications [3] to be correlated with the QRS transition zone and this was confirmed to be a major determinant in a large Japanese CT-scan study done in 1991. The findings of the latter study were that about two thirds of the transition zone appearance on the 12-lead ECG could be explained by anatomical rotation of the heart around the long axis as measured by the left sided angle between the horizontal axis of the body and the interventricular angle (“the septal angle”) [4]. In recent times both clockwise (CW) and counterclockwise (CCW) rotation of the transition zone of the QRS have been significantly and independently shown to be prognostic of future mortality.
