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 ...

Reentry arrhythmia occurs when electrical signals in the heart deviate from their usual path, creating a loop that causes repeated stimulation and disrupts the heart’s rhythm. Symptoms of reentry ...

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 ...

The sinoatrial (SA) node is the natural pacemaker of the heart. It generates electrical impulses that cause the heart’s chambers to contract, setting the heart rate. The SA node typically generates 60 ...

A DZHK research team at the University Medical Center Mainz has discovered a new signaling pathway of the coagulation system that controls scar formation after a heart attack. If this signaling ...

Find out can ecg detect heart attack progression and learn how an electrocardiogram test identifies immediate muscle damage ...

New research into human heart development has shed light on the way heart muscle cells contract. A correctly beating heart is vital to a baby's growth during pregnancy, helping guard against heart ...
