In patients undergoing transcatheter aortic valve replacement (TAVR), high‑grade atrioventricular blocks occurring during and after the procedure had distinct mechanisms and predictors. Both ...
2:1 atrioventricular block is a form of second-degree AV nodal block and occurs when every other P wave is not conducted through the AV node to get to the ventricles, and thus every other P wave is ...
A first-degree atrioventricular node block occurs when conduction through the AV node is slowed, thereby delaying the time it takes for the action potential to travel from the sinoatrial node through ...
Heart block is a disruption in the electrical signals that control your heart. Your heart depends on a steady flow of electrical signals that start in the heart’s upper chambers (atria). The signals ...

Patients with high-grade atrioventricular block are routinely treated with cardiac pacing; however, the most efficacious mode of pacing has not been identified. Although nonrandomized studies have ...
NEW YORK, NY—High-grade atrioventricular (AV) block occurs within 1 month for roughly one in seven patients who undergo transcatheter tricuspid valve replacement (TTVR), according to new results from ...
Your heart isn’t plugged into an outlet. And you don’t use a switch to turn it on. But just like a lamp, your heart runs on an electrical system. Every time your heart beats, an electrical signal ...
