Prevalence of Functional Mitral Regurgitation in Patients with Chronic Heart Failure
Secondary or functional mitral regurgitation (FMR) is a common problem in patients with chronic heart failure (HF) due to dilated cardiomyopathy, regardless of aetiology.1 FMR results from an imbalance between the closing and the tethering forces that act on the mitral valve leaflets.2,3

His bundle pacing in humans was first described in 1970 by Narula et al.1 They demonstrated that it was possible to stimulate the His bundle to produce normal physiological ventricular activation via the His-Purkinje system. However, the first report of permanent His bundle pacing, by Deshmukh et al., did not occur until 2000.2 In that study, His pacing was performed in a series of patients with…

EHRA 23– Dr Bruce Wilkoff (Cleveland Clinic, US) joins us on-site to outline the findings of the AdaptResponse randomized study (NCT02205359).
In AdaptResponse, investigators studied the hypothesis that cardiac resynchronization therapy (CRT) devices which utilised AdaptivCRT® (aCRT) algorithm (Medtronic) had better prognosis in patients with normal atrioventricular conduction and left bundle…

In patients with syncope or episodes of palpitations and heart disease, an electrophysiology study (EPS) may be of value by means of potential induction of sustained ventricular tachyarrhythmias.1,2 Programmed ventricular stimulation may be useful in the context of risk stratification of ischaemic patients with left ventricular ejection fraction (LVEF) 30–40 %, and there has been some evidence…

In this short interview from HRS 2022, Dr Pugazhendi Vijayaraman (Geisinger Heart Institute, Wilkes-Barre, Pennsylvania, US) outlines the findings from the CSP-SYNC trial which investigated the effects of conduction system pacing as compared to conventional biventricular pacing in patients with heart failure with preserved ejection fraction (HFpEF).

The term narrow QRS tachycardia indicates individuals with a QRS duration ≤120 ms, while wide QRS tachycardia refers to tachycardia with a QRS duration >120 ms.1 Narrow QRS complexes are due to rapid activation of the ventricles via the His–Purkinje system, suggesting that the origin of the arrhythmia is above or within the His bundle. However, early activation of the His bundle can also occur…
