Ventricular arrhythmias originating from right ventricle have unique electrocardiographic (ECG) characteristics that can be utilized to localize the origin of the arrhythmia. This is crucial in pre-procedural planning particularly for ablation treatments. Moreover, non-ischaemic structural heart diseases, such as infiltrative and congenital heart diseases, are associated with the VAs that exhibit particular ECG findings. This article comprehensively reviews discriminatory ECG characteristics of VAs in the right ventricle with and without structural right ventricular diseases. Although striking racial and ethnic disparities in health are manifest during later life, they may be rooted in early-life exposures. Drawing from cumulative inequality theory, we investigate whether life course stressors are associated with risk of later life functional limitations and whether this relationship differs by race and ethnicity. We utilize longitudinal data from the Health and Retirement Study to test whether child and adult stressors predict trajectories of the occurrence and severity of functional limitations among a diverse sample of older adults. Child and adult stressors are associated with greater occurrence and severity of functional limitations during later life. Mediation analyses reveal the indirect influence of child stressors via adult stressors on occurrence and severity of functional limitations; however, the indirect effects are slightly stronger for Black and Hispanic adults than their White counterparts. Child stressors, in and of themselves, do not increase functional limitations among Black and Hispanic people but are associated with greater adult stress exposure, predisposing them to more functional limitations. Results suggest that childhood stressors are associated with distinct social pathways
