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 ...

Figure 2: Reduction in heart rate during atrial fibrillation after Gα i2 gene transfer. This study is the first report of intracoronary site-specific gene transfer and the first use of gene therapy to ...

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 ...

This is the last in a three-part series on using an electrocardiogram to assess the heart’s electrical activity. In this article, the focus is on cardiac rhythm and conduction abnormalities of the ...

The future of heart disease diagnoses is set to change forever, thanks to a new AI tool and a device most of us already own.

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 ...

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 ...

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 ...

We’ve all heard warnings about BPA, a chemical found in plastics and personal care products. Studies show that nearly 90% of Americans have detectable levels of BPA in their bodies. Now, new research ...

(PhysOrg.com) -- 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 ...
