Differential effects of adrenergic antagonists (Carvedilol vs Metoprolol) on parasympathetic and sympathetic activity: a comparison of clinical results

Welcome to the latest issue of the European Journal of Arrhythmia & Electrophysiology, the official journal of the Arrhythmia Alliance. We are honoured to present a series of compelling articles that reflect cutting-edge developments and diverse perspectives in this ever-evolving ...

Ventricular tachycardia (VT) ablation presents a challenging and growing area of focus in the realm of complex ablation, with promises of improved patient’s quality of life and clinical outcomes.1,2 Classic approaches to VT ablation centered on arrhythmia induction and ...

For decades, right ventricular pacing (RVP) has been the leading pacing technique and has been proven to be effective in treating patients with symptomatic bradycardia. However, dyssynchrony caused by non-physiological ventricular activation results in pacing-induced cardiomyopathy occurs in approximately 15% of ...

Supraventricular tachycardia (SVT) is an important cause of intrusive palpitation symptoms. This expert interview explores a nurse-led end-to-end pathway for the diagnosis, assessment and management of this condition. It was conducted at the Barts Heart Centre of Barts Health NHS ...

Highlights Failure to target and deliver durable radiofrequency lesions to all functionally critical areas has been identified as an important cause of ventricular tachycardia recurrence and is particularly challenging in deep midmyocardial or very extensive substrate where point-by-point radiofrequency ablation ...

Bradycardia, renal failure, atrioventricular nodal blockade, shock and hyperkalemia (BRASH) syndrome is a rare, often unrecognized but potentially life-threatening clinical entity that is characterized by the pentad of symptoms after which it is named. BRASH syndrome is seen most commonly ...

Radiofrequency (RF) ablation involves delivering medium-to-high-frequency alternating current, which is electrically conducted to cardiac tissue that constitutes a part of the circuit. The unipolar circuitry contains the generator, transmission lines, catheter, cardiac tissue, interposed tissue and dispersive electrode (ground pad/...

Several smart, connected and direct-to-consumer wearable devices capable of detecting cardiac arrhythmias have proliferated in the marketplace in the last decade. Increasingly, these devices are being marketed as “medical grade” in addition to “wellness” devices.1 New iterations of smartwatch and ...

Introduction: With the ever-increasing importance of home monitoring for the follow-up of cardiac implanted electronic devices (CIED), emphasised during the COVID pandemic, the workload for CIED follow-up clinics has grown exponentially. The demand on services is exceeding resource, with innovative ...

Welcome to a new issue of the European Journal of Arrhythmia & Electrophysiology. As the ongoing coronavirus disease 2019 (COVID-19) pandemic continues to provide unprecedented challenges for electrophysiologists and other healthcare providers who manage arrhythmias, we hope you find these topical ...

The current outbreak of coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has developed into a worldwide pandemic affecting millions of lives in one way or another.1 Over the period of 1 year since the disease was first ...

Paroxysmal supraventricular tachycardia (PSVT) defines a group of cardiac arrhythmias where the underlying mechanism is dependent upon structures at or above the level of the atrioventricular node. The recent PRE-EMPT study retrospectively evaluated health records of over 4.2 million people in ...
