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 ...

This release is available in Chinese. New research indicates that a finding on a routine electrocardiogram that signals a disorder of the electrical conducting system in one part of the heart and ...

Sudden cardiac death resulting from fibrillation -- erratic heartbeat due to electrical instability -- is one of the leading causes of death in the United States. Now, researchers have discovered a ...

Many studies have demonstrated that macrophages have multiple functions in different organs and tissues beyond their classical phagocytic activity. However, the specific functions of heart-resident ...

Electrical problems in the heart can often lead to serious and fatal complications including complete heart block or heart failure. Left ventricular conduction disease occurs when there is an ...

Sept. 25 (UPI) --Researchers have succeeded in creating a digital twin that for the first time replicates the heart's electrical conduction system, which coordinates heartbeats, a new study says. The ...

Heart rhythm problems occur when heart muscle cells fail to properly transmit electrical signals that coordinate blood pumping. Now, scientists at Duke University have devised a promising method to ...

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 ...

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 ...
