Shortening of the Short Refractory Periods in Short QT Syndrome. [PDF]
BACKGROUND: Diagnosis of short QT syndrome (SQTS) remains difficult in case of borderline QT values as often found in normal populations. Whether some shortening of refractory periods (RP) may help in differentiating SQTS from normal subjects is unknown.

Atrioventricular Reciprocating Tachycardia Mediated by Twin Atrioventricular Nodes
A 21-year-old man with univentricular and uniatrial heart came for a third attempt at ablation of recurrent supraventricular tachycardia. He had undergone a previous cardiac surgery of a Blalock–Taussig shunt, and bidirectional Glenn, and the electrophysiological study revealed an ...

This systematic review identified 24 clinical trials of medical device and surgical interventions for HFpEF, with 16 demonstrating at least safety and feasibility, but little evidence of long‐term benefit. Phenotype‐based responses suggest that certain interventions may benefit specific HFpEF subgroups, yet most trials suffered from heterogeneous ...

Frequency-dependent anti arrhythmic effects of crataegus monogyna on the extracellular field potential recordings in the rabbit atrioventricular node, an experimental model of AF [PDF]
Introduction: Despite extensive studies that have been performed on the effects of Crataegus monogyna in cardiovascular diseases, only few investigations have addressed the antiarrhythmic properties of this plant.

Arrhythmia‐induced cardiomyopathy (AIC) in left ventricular systolic dysfunction with atrial fibrillation (AF). HFrEF, heart failure with reduced ejection fraction; LVEF, left ventricular ejection fraction; MRI, magnetic resonance imaging. Abstract Aims Atrial fibrillation (AF) ablation in heart failure reduces mortality and hospitalizations and ...

Key Clinical Message Atrial flutter (AFL) and supraventricular tachycardia (SVT) are common arrhythmias in clinic. However, some AFL cases may present additional complexities, such as both accessory pathways (AP) and dual atrioventricular node pathways ...

Radiofrequency Catheter Ablation of Atrioventricular Nodal Reentrant Tachycardia: It Is Not Always As It Is Expected [PDF]
Observation of Coincident arrhythmias is not uncommon but the co-existence of idiopathic verapamil sensitive left ventricular tachycardia (ILVT) with other arrhythmias is very rare.

Junctional ectopic tachycardia (JET)
Junctional ectopic tachycardia (JET) is a tachyarrhythmia arising from the atrioventricular node and His bundle area. Enhanced normal automaticity has been postulated as the mechanism of JET in the majority of patients.
