After heart surgery, some patients develop a condition called new-onset atrial fibrillation, where the heart's upper chambers beat irregularly. This study uses a non-invasive technology called CardioInsight 3D Mapping—a special vest with 252 sensors placed on your chest—to create a detailed map of where the abnormal electrical activity is coming from in your heart.
Abnormal heart rhythms after surgery are common and can lead to longer hospital stays, increased risk of stroke, and other complications. By pinpointing exactly where these rhythm problems start and maintain themselves, doctors hope to develop better prevention and treatment strategies in the future.

If you develop an abnormal heart rhythm within the first week after your surgery, the research team will place a special 252-electrode vest on your chest to map your heart's electrical activity. You'll also have a low-dose CT scan of your chest. The mapping procedure is non-invasive, meaning nothing goes inside your body—the vest simply sits on your skin to detect your heart's signals from the outside.
