Orthodromic atrioventricular reentrant tachycardia using a concealed isoproterenol-sensitive accessory pathway

open access: yesIndian Pacing and Electrophysiology Journal, 2020
Accessory pathways (APs) represent the substrate for atrioventricular reentrant tachycardia. Catecholamine-sensitivity is an uncommon feature of APs and has been almost exclusively been described in APs with antegrade conduction. We present the rare case

Assessment of the neutrophil/lymphocyte ratio in patients with supraventricular tachycardia

open access: yesAnatolian journal of cardiology, 2015
Objective: The neutrophil/lymphocyte ratio (NLR) has been evaluated as a new predictor of cardiovascular risk. Inflammation has been shown to be associated with various arrhythmias including supraventricular tachycardias (SVTs).

Coexistence of Atrioventricular Nodal Reentrant Tachycardia and Idiopathic Left Ventricular Outflow-Tract Tachycardia [PDF]

open access: yes, 2005
Double tachycardia is a relatively rare condition. We describe a 21 year old woman with history of frequent palpitations. In one of these episodes, she had wide complex tachycardia with right bundle branch and inferior axis morphology.

Advanced ablation strategies for management of post-surgical atrial arrhythmias. [PDF]

open access: yes, 2013
Post-surgical arrhythmias include a wide range of arrhythmias occurring late after cardiac surgery and represent a complex substrate for catheter ablation either because of extended scar and remodeling or because of limited access to the area of interest.

Cardiac arrhythmia prevalence and risk factors in 24‐h electrocardiograms of sedentary horses

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Cardiac arrhythmias are common in horses, but their clinical relevance remains controversial. Objectives To describe prevalence and identify risk factors for arrhythmias that may warrant additional screening in a sedentary mixed‐breed population of horses. Study Design Prospective cross‐sectional.

Implantable Defibrillators: Which Is the Best Device for Each Patient?

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT The first viable alternative to surgical implantation of an epicardial defibrillator system for secondary prevention of sudden cardiac death (SCD) was a single chamber transvenous implantable cardioverter defibrillator (ICD). Thanks to technological advancements over the past 40 years, electrophysiologists now have several options when ...

Conversion of supraventricular arrhythmias to sinus rhythm using flecainide [PDF]

open access: yes, 2017
We evaluated the efficacy of flecainide acetate (given intravenously to a maximal dose of2 mg kg−1 and then orally in a dose of 100 mg b.d. or 100 mg t.d.s.) in the conversion to sinus rhythm of 50 patients exhibiting supraventricular arrhythmias (39 ...

Antenatal antiarrhythmic treatment for fetal tachyarrhythmias: a study protocol for a prospective multicentre trial [PDF]

open access: yes, 2017
Introduction Several retrospective or single-centrestudies demonstrated the efficacy of transplacentaltreatment of fetal tachyarrhythmias. Our retrospectivenationwide survey showed that the fetal therapy willbe successful at an overall rate of 90%.

Intermittent Ventricular Pre‐Excitation: Clinical Features and Electrophysiological Properties

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Intermittent ventricular pre‐excitation has long been considered a low‐risk marker for sudden death. Accessory pathways (APs) with high‐risk intermittent antegrade conductive properties may exist, but this still represents a gray area in current guidelines.
