Cardiac device therapy has significantly evolved since the introduction of the first implantable pacemaker and the subsequent ...

INJURY to the invisible subendocardial conduction system during surgical closure of congenital defects in the ventricular septum is an uncommon but extremely grave complication. 1,2 Impalement of ...

Research by Boston Children's validates an innovative approach to mapping the heart's invisible conduction tissue during ...

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

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

During a severe heart attack many heart muscle cells die and are replaced by scar tissue to stabilize the heart wall. Connective tissue cells, known as fibroblasts (FB), are the dominant cell type in ...

Peter Spector, M.D.; Nicole Habel, M.D. With H and V-capture there is a combination of these findings. Local V activation is early, QRS onset is early, and QRS end is also early. The QRS duration is ...

These days having both a land line and a mobile phone seems like overkill. But Virginia Tech researchers have shown that the heart relies on at least two key communication channels to keep abnormal ...
