This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This research study is testing a new imaging technique called electrocardiographic imaging (ECGi) to help doctors see and map dangerous heart rhythms caused by scar tissue from a previous heart attack. The study will compare this new imaging method with standard heart mapping techniques before and after you receive a catheter ablation procedure — a treatment designed to stop these dangerous rhythms. Researchers hope this imaging technique will help doctors treat heart rhythm problems more effectively in the future.
Many patients with heart rhythm problems caused by old heart attacks need treatment, but doctors don't always have the best tools to pinpoint exactly where the problem is. This study is testing whether this new imaging technique can help doctors map and treat these dangerous rhythms more accurately than current methods alone.

You likely don't qualify if…
Within one week before your ablation procedure, you will have heart imaging (MRI or CT scan) and electrical mapping tests using 120 ECG patches on your body. Then you will receive your standard catheter ablation procedure as planned. Within one week after the procedure, you will repeat the heart imaging and electrical mapping tests. Finally, at 6 months after your procedure, you will have a follow-up visit where doctors will check how well the treatment worked using your defibrillator device's information.
