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.

The cardiac conduction system (CCS) has a vital role in initiating and coordinating nearly 3 billion heartbeats throughout a person’s lifetime. The CCS comprises two primary tissue types: the ...

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 ...

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

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 ...

Most congenital and acquired cardiac diseases feature structural remodeling of the myocardium, including fibrosis and loss of cardiomyocytes and/or their alignment (disarray), which can contribute to ...
