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 ...

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 ...

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 ...

Cardiac arrhythmias affect millions across the world and are responsible for a fifth of all deaths in the Netherlands. Currently there are multiple treatment options, ranging from life-long medication ...

It has been shown that enalapril, an angiotensin-converting enzyme (ACE) inhibitor, decreases the intracellular resistance and increases the conduction velocity in the heart of adult rats and cardio- ...

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 ...

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 ...
