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 ...

For the past two decades, catheter ablation stole most of the excitement in electrophysiology. Cardiac pacing was seen as necessary but boring. His-bundle pacing earned only modest attention. But at ...

A reusable vest that can map the electric impulses of the heart in fine detail could detect abnormalities from a potentially fatal heart disease much earlier than is currently possible, a new study ...

The heart is the body's hardest-working muscle. Whether you're awake or asleep, or exercising or resting, your heart is always at work. It pumps blood through arteries to deliver oxygen to organs and ...

Medtronic "Conduction System Pacing" Expanded Indication Now Includes Left Bundle Branch Area Pacing in Addition to His-Bundle Pacing for Patients with Slow Heart Rates Medtronic is the first and only ...

When heart muscle gets damaged, the result is often permanent. Unlike other muscles in the body, the heart has long been believed to lack the ability to heal itself. But recent research suggests that ...

Research by Boston Children's validates an innovative approach to mapping the heart's invisible conduction tissue during ...

Patients with atrioventricular (AV) block who don’t have an indication for cardiac resynchronization therapy (CRT) do better when treated with conduction-system pacing versus right ventricular septal ...

These two conditions affect how well your heart can pump blood. Cardiomyopathy can sometimes lead to heart failure. Cardiomyopathy and heart failure are both conditions in which your heart has a more ...
