New research in Sweden has produced a "blueprint" revealing how the human heart is built during prenatal development. It offers insights that could lead to improved prenatal care and new treatments ...

New research highlights postnatal regeneration limits and pathological remodeling of the cardiac conduction system after myocardial infarction, uncovering mechanisms behind clinical arrhythmogenesis ...

For patients with heart failure, a reduced ejection fraction, and an indication for cardiac resynchronization therapy (CRT), using His-Purkinje conduction system pacing (HPCSP) is safe and feasible ...

Cardiac device therapy has significantly evolved since the introduction of the first implantable pacemaker and the subsequent development of the implantable cardioverter-defibrillator (ICD). ICDs are ...

In a new study, published July 12 in Nature, researchers have produced the most detailed and comprehensive human Heart Cell Atlas to date, including the specialized tissue of the cardiac conduction ...

Discordant results from two trials comparing conduction system pacing with biventricular pacing for cardiac resynchronization therapy (CRT) leave open the question of whether conduction system pacing ...

For the past two decades, catheter ablation stole most of the excitement in electrophysiology. Cardiac pacing was seen as necessary but boring. His-bundle pacing earned only modest attention. But at ...

Cardiac physiologic pacing, also known as cardiac resynchronization therapy, is indicated in patients with heart failure, reduced left ventricular ejection fraction (LVEF) of 50% or less, and either a ...

Patients with atrioventricular (AV) block who don’t have an indication for cardiac resynchronization therapy (CRT) do better when treated with conduction-system pacing versus right ventricular septal ...

NEW ORLEANS -- Among patients with heart failure, conduction system pacing-guided cardiac resynchronization therapy was associated with improvements in left ventricular ejection fraction (LVEF) ...

ECG aberrancy means the heartbeat does not follow the usual conduction system of the heart. Atrial fibrillation with ECG aberrancy means people have an irregular heart rhythm with abnormal conduction.
