It is with pride and gratitude that we reflect on the remarkable 10-year journey of European Journal of Arrhythmia & Electrophysiology. With the vital contributions of all of our esteemed authors, reviewers and editorial board members, the journal has served ...

Postural tachycardia syndrome (PoTS) is a chronic condition, predominately affecting women between the ages of 15 and 50, and prevalence is estimated to be 0.2%.1,2 It is characterised by an abnormal response by the autonomic nervous system to changes in posture causing lightheadedness ...

Catheter ablation (CA) is an invasive adjunctive therapeutic option for atrial and ventricular arrhythmias, in uncontrolled cases, following optimal medical therapy.1,2 The validation of 3D mapping and its implementation into clinical usage has been a remarkable achievement in the field ...

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 ...
