Detection of Atrial Fibrillation Through Voice Signal Processing

This study is testing a new technology that listens to a person's voice during short phone calls to help identify heart rhythm problems. The goal is to see if voice signal analysis can tell the difference between a normal rhythm (sinus rhythm) and an irregular rhythm (atrial fibrillation). We are enrolling adults scheduled for a standard heart procedure called cardioversion, which is used to reset the heart to a normal rhythm. Each participant will provide voice recordings through three short phone calls: before cardioversion, just after the procedure, and at a follow-up visit. Results will be compared with standard heart rhythm tests (electrocardiograms or ECGs). This research may lead to a simple, low-cost way to monitor heart rhythms remotely without requiring special devices.
