Abstract Background Predicting the origin of premature ventricular contraction (PVC) from the preoperative electrocardiogram (ECG) is important for catheter ablation therapies. We propose an explainable method that localizes PVC origin based on the s

Torsades de Pointes (TdP) refers to a polymorphic ventricular tachycardia (VT) with undulating QRS axis that occurs in long QT syndrome (LQTS), although the term has been used to describe polymorphic ventricular tachyarrhythmias in which QT intervals

Causes of heart failure can be investigated by tracing imperfections in electrical current propagation on the millimetre scale; however, the spatial resolution of current magnetocardiograph methods are limited to the centimetre-scale. Here, the autho

Cardiac immune cells play various roles in the maintenance of homeostasis and diseases in the heart. Here the authors show that cardiac resident macrophages are a critical regulator of cardiac impulse conduction through amphiregulin production, contr

We propose an in-silico deep reinforcement learning scheme that combines a computer simulation model of cardiac tissue and deep reinforcement learning to unveil an effective ablation strategy for atrial fibrillation (AF). The deep neural network-base

Purpose We hypothesized that linear regional cooling (LRC) toward the atrio-ventricular groove (AV-G) can move the spiral wave (SW) center to the AV-G effectively and terminate SW. The effectiveness of LRC in ex vivo 2D ventricle rabbit experiments w

Background Electrical storm (ES) is a life-threatening emergency in patients at high risk of ventricular tachycardia/ventricular fibrillation (VF), but the pathophysiology and molecular basis are poorly understood. Objective The purpose of this study

Atrial fibrillation (AF) is the most common arrhythmia in adults; it affects approximately 0.8 million patients in Japan alone. Yet despite many years of basic and clinical research, the exact mechanisms underlying the initiation and maintenance of A
