Testing a new device to prevent irregular heartbeat after heart surgery

This study is testing a new device called DefiPace that uses low-energy electrical pulses to prevent and treat an irregular heart rhythm called atrial fibrillation that sometimes happens after heart surgery. The researchers want to see if this device is safe and effective at preventing this complication in real-world hospital settings. The trial has two parts: one that looks at current standard care, and another that tests the new device in patients who receive a special temporary pacing system during surgery.

Atrial fibrillation is a common and serious complication after heart surgery that can cause problems and require additional treatment. This study exists to see whether using gentle electrical pacing can prevent this irregular heartbeat from happening in the first place, which could help patients recover better and avoid further complications.
