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 ...

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 ...

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 ...

Macrophages have a previously unrecognized role in helping the mammalian heart beat in rhythm. Researchers have discovered that macrophages aggregate around central cardiac cells that regulate ...

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 ...

The conduction disturbance persisted after the febrile illness resolved, and we determined no evidence of structural heart disease (echocardiography) or systemic diseases associated with conduction ...

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 ...

The heart rate is the number of times the heart beats per unit of time. There are several abnormalities of this rate and rhythm. This is a term that describes different conditions in which the heart ...

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