Dynamics of conduction blocks in a model of paced cardiac tissue [PDF]

, 2005
We study numerically the dynamics of conduction blocks using a detailed electrophysiological model. We find that this dynamics depends critically on the size of the paced region.

Postcardiac injury syndrome caused by radiofrequency catheter ablation of persistent atrial fibrillation: severe pulmonary arterial hypertension with severe tricuspid regurgitation: a rare case report and literature review

BMC Cardiovascular Disorders, 2023
Background Postcardiac injury syndrome (PCIS) is an easy-to-miss diagnosis, but it is not an uncommon complication. The phenomenon of echocardiography (ECHO) showing both severe pulmonary arterial hypertension (PAH) and severe tricuspid regurgitation (TR)

Hybrid Ablation of Atrial Fibrillation: A Contemporary Overview

Journal of Cardiovascular Development and Disease, 2022
Electrical isolation of pulmonary veins (PVI) is the cornerstone of invasive treatment of atrial fibrillation (AF). However, arrhythmia-free survival of a PVI only approach is suboptimal in patients with persistent and long-term persistent AF.

Role of cardiac resynchronization therapy in the development of new-onset atrial fibrillation: A single-center prospective study. [PDF]

, 2012
Albeit several studies examined the association between cardiac resynchronization therapy (CRT) and atrial fibrillation (AF) in heart failure (HF), results are still unclear and quite conflicting.

Durability of pulmonary vein isolation following cryoballoon ablation: Lessons from a large series of repeat ablation procedures

International Journal of Cardiology: Heart & Vasculature, 2022
Introduction: The second-generation cryoballoon (CB) has emerged in the last decade as an effective treatment for atrial fibrillation (AF). This study sought to analyze the rate of PV reconnection following CB ablation, evaluate the most frequent PV ...

Cardiac Memory-induced T-wave Inversions [PDF]

, 2020
Introduction: Cardiac memory refers to T-wave inversions that result when normal ventricular activation resumes following a period of abnormal ventricular activation.Case Report: We present a case of a 29-year-old man with a pacemaker who presented with ...

Ventricular divergence correlates with epicardial wavebreaks and predicts ventricular arrhythmia in isolated rabbit hearts during therapeutic hypothermia [PDF]

, 2020
INTRODUCTION: High beat-to-beat morphological variation (divergence) on the ventricular electrogram during programmed ventricular stimulation (PVS) is associated with increased risk of ventricular fibrillation (VF), with unclear mechanisms.

Indeterminacy of Spatiotemporal Cardiac Alternans

, 2008
Cardiac alternans, a beat-to-beat alternation in action potential duration (at the cellular level) or in ECG morphology (at the whole heart level), is a marker of ventricular fibrillation, a fatal heart rhythm that kills hundreds of thousands of people ...

Effects of early afterdepolarizations on excitation patterns in an accurate model of the human ventricles [PDF]

, 2017
Early Afterdepolarizations, EADs, are defined as the reversal of the action potential before completion of the repolarization phase, which can result in ectopic beats.
