Antiarrhythmic and proarrhythmic effects of subcutaneous nerve stimulation in ambulatory dogs [PDF]

, 2019
Background High output subcutaneous nerve stimulation (ScNS) remodels the stellate ganglia and suppresses cardiac arrhythmia. Objective To test the hypothesis that long duration low output ScNS causes cardiac nerve sprouting, increases plasma ...

Cryoballoon or Radiofrequency Ablation for Paroxysmal Atrial Fibrillation.

New England Journal of Medicine, 2016
BACKGROUND Current guidelines recommend pulmonary-vein isolation by means of catheter ablation as treatment for drug-refractory paroxysmal atrial fibrillation. Radiofrequency ablation is the most common method, and cryoballoon ablation is the second most

The 4q25 variant rs13143308T links risk of atrial fibrillation to defective calcium homoeostasis [PDF]

, 2019
Aims: Single nucleotide polymorphisms on chromosome 4q25 have been associated with risk of atrial fibrillation (AF) but the exiguous knowledge of the mechanistic links between these risk variants and underlying electrophysiological alterations hampers ...

Atrioventricular complete block occurring 12 years after successful ablation of slow-slow atrioventricular nodal reentrant tachycardia

Türk Kardiyoloji Derneği Arşivi, 2013
Atrioventricular nodal reentrant tachycardia (AVNRT) is the most frequent form of paroxysmal supraventricular tachycardia. Selective radiofrequency (RF) catheter ablation of the slow pathway is an ideal method for treatment of patients with AVNRT ...

Right‐sided Mahaim‐mediated tachycardia combined with atypical atrioventricular nodal reentrant tachycardia and left free wall accessory pathway: A case report

Annals of Noninvasive Electrocardiology, 2022
A 37‐year‐old man was admitted to our hospital with paroxysmal palpitation for half year. A previous electrogram showed a narrow complex tachycardia. Electrophysiologic study (EPS) found a concealed left‐sided free wall pathway accessory.

Corrected QT dispersion as a predictor of the frequency of paroxysmal tachyarrhythmias in patients with Wolff–Parkinson–White syndrome

Egyptian Journal of Chest Disease and Tuberculosis, 2014
Background: Patients with Wolff–Parkinson–White (WPW) syndrome are prone to develop a variety of tachyarrhythmias which may lead to unpleasant, disabling symptoms and in extreme, sudden cardiac death (SCD).
