Scientists studying genetic data from nearly 50,000 people have uncovered several DNA sequence variations associated with the electrical impulses that make the heart beat. The findings may pave the ...

What Is the Heart Conduction System? The heart conduction system is made up of cells, nodes, and signals that help your heart to beat. In fact, the cardiac conduction system is responsible for our ...

September 29, 2011 (Baltimore, Maryland) — Delivering a high-frequency alternating current (HFAC) blocks electrical conduction from cell to cell in the heart, a finding that might one day eliminate ...

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 ...

THERE is evidence that an increase in heart rate is accompanied by a decrease in the velocity of impulse conduction in heart muscle 1–2. We have therefore looked for interdependence between the ...

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

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 ...

Medtronic "Conduction System Pacing" Expanded Indication Now Includes Left Bundle Branch Area Pacing in Addition to His-Bundle Pacing for Patients with Slow Heart Rates Medtronic is the first and only ...

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

A hypothesis, suggested previously by morphological studies, for impulse conduction from the sarcolemma to the contractile material via the sarcoplasmic reticulum is discussed. The relation of ...

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 ...
