Sex Hormones and Repolarization Dynamics in Women with Long QT Syndrome
Author(s): Ilan Goldenberg Added: 1 year ago
In this video from HRS 2022, Dr Ilan Goldenberg (University of Rochester Medical Center, Rochester, NY, US) joins us to discuss the findings of a recent study which aimed to evaluate the effect of sex hormones during the menstrual cycle on repolarisation dynamics in women with congenital and drug-induced long QT syndrome. Discussion points: 1. Aim, and endpoints 2. Study design 3. Key findings 4… View more

Author(s): Konstantinos D Rizas , Wolfgang Hamm , Stefan Kääb , et al Added: 3 years ago
Experimental and clinical studies have demonstrated that enhanced sympathetic autonomic nervous system (SANS) activity can destabilise myocardial repolarisation,1–4 increasing vulnerability to developing fatal cardiac arrhythmias.5–8 Accordingly, assessment of SANS activity has always been a major goal for cardiac risk stratification methods. Various non-invasive methods including assessment of… View more

The pathophysiology of AF is complex and incompletely understood to date.1,2 AF is a progressive disease of the atria involving a multitude of mechanisms related to its initiation, maintenance and progression. Experimental evidence suggest that AF is characterised by alternations in atrial size, shape electrophysiology, autonomic innervation, and cardiomyocyte metabolism, as well as development… View more

The incidence of ventricular arrhythmias is often related, within an individual, to the rate of their underlying sinus rhythm (heart rate). The direction of this relationship is generally considered to entail some prognostic significance: whereas ectopic activity suppressed by tachycardia is assumed to be benign, an arrhythmia enhanced by tachycardia is regarded with more concern. Is this… View more
