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 recent study to be presented at the American Heart Association (AHA) Scientific Sessions 2022* revealed unexpected changes in the electrical conduction system of the first genetically-modified ...

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 ...

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 ...

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 ...

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 ...

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 ...

Scientists today track electrical signals and voltage changes in neurons and muscle cells by labeling individual cells or probing with electrodes. Scientists have now developed a new type of sensor ...
