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 ...

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 ...

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 ...

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 ...

The QRSs are wider than and different from other QRSs, raising a possibility of PVC. But they are clearly preceded by a prematurely occurring P wave and so are PAC with aberrant conduction. Aberrant ...

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 ...

Electrocardiogram (ECG) measures taken after the first pig-to-human heart transplant found significantly different electrical conduction characteristics compared to those seen in native pig hearts ...

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- ...

A research team led by investigators at Beth Israel Deaconess Medical Center (BIDMC) and Seoul National University has developed a new electric mesh device that can be wrapped around the heart to ...
