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 ...

In mice, blocking heart-to-brain signals improved healing after a heart attack, hinting at new targets for cardiac therapy.

Heart failure symptoms have been reversed in patients with a new pacemaker that changes how the heart is fuelled.

A new therapy to re-engage the heart's natural electrical pathways - instead of bypassing them - could mean more treatment options for heart failure patients who also suffer from electrical ...

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 ...
