The presence of abnormal substrate left atrium is a predictor atrial fibrillation (AF) recurrence after pulmonary vein isolation. We aimed to investigate the isochronal late activation mapping access conduction velocity for predicting AF ablation outcome. Forty-five paroxysmal patients (30 males, 57.8±8.7 years old) who underwent isolation were enrolled. Isochronal was retrospectively constructed with 2 different windows interest: from onset P wave QRS on surface electrocardiography (W1) and...
Abstract Rationale: Although novel oral-anticoagulants are widely used in patients with atrial fibrillation (AF) for stroke prevention, there was only limited evidence their use left ventricular (LV) thrombus. Patient concerns: A 41-year-old man who presented acute onset of right-hand clumsiness and aphasia even under high international normalized ratio (INR: 7.64) from warfarin use. He previously treated the LV thrombus non-valvular AF. Brain magnetic resonance imaging (MRI) showed multiple...
(1) Background: The autonomic imbalance plays a role in vasovagal syncope (VVS) diagnosed by head-up tilting test (HUT). neuECG is new method of recording skin electrical signals to simultaneously analyze sympathetic nerve activity (SKNA) and electrocardiogram. We hypothesize that SKNA higher subjects with tilt-positive than tilt-negative the surges before syncope. (2) Methods: recorded 41 who received HUT (according "Italian protocol"), including rest, tilt-up, provocation recovery phases....
Abstract Catheter ablation for tachyarrhythmia via superior approach has been used in patients without possible inferior vena cava access such as cases of venous occlusion or complex anomaly. Difficulty catheter manipulation, instability, number required vascular access, and radiation exposure operator had described the procedure. Application three‐dimensional (3‐D) mapping system could navigate guiding provide more precise ablation. We reported four receiving due to atrioventricular nodal...
Autonomic system plays a pivotal role in the pathogenesis of paroxysmal atrial fibrillation (AF). Skin sympathetic nerve activity (SKNA) is noninvasive tool for assessing tone. However, data on changes SKNA after ablation are limited. Here, we retrospectively enrolled 37 patients with symptomatic drug-refractory AF who underwent pulmonary vein isolation (PVI) radiofrequency (RFA) or cryoablation (CBA). was measured from chest and right arm 1 day prior to ablation, as well 3 months ablation....
Dynamic display of real-time wavefront activation pattern may facilitate the recognition reentrant circuits, particularly diastolic path ventricular tachycardia (VT).We aimed to evaluate feasibility LiveView Display for mapping critical isthmus scar-related VT.Patients with mappable VT were selected. The characteristics underlying substrates and circuits assessed using HD grid multielectrode catheter. isthmuses identified based on map, entrainment, ablation results. accuracy findings in...

Unsuccessful endocardial ablation for perimitral atrial flutter (AFL) could be attributed by the epicardial bridging.This study aimed to investigate electrophysiological characteristics of breakthrough during catheter AFL.This retrospective recruited 40 patients who received successful AFL from January 2016 June 2021. The were divided into two groups: group 1 (n = 18) ablation, and 2 22) following unsuccessful owing incomplete mitral block or unachievable termination AFL. local electrogram...
