This trial is testing a newer heart rhythm procedure called pulse field ablation (PFA) that treats paroxysmal atrial fibrillation—a type of irregular heartbeat. Researchers want to understand how this procedure immediately affects your heart's ability to pump blood, using special ultrasound imaging taken during the treatment itself.
Doctors need to know whether the new treatment causes any temporary stunning or weakening of the heart after the procedure, so they can better decide how to manage blood thinners and other care afterward.

You will receive the heart rhythm procedure as planned, but researchers will use ultrasound imaging (called intracardiac echocardiography) at the beginning and end of your procedure to measure how your heart is pumping. This imaging is done through the same access point used for the procedure itself, so it does not require additional punctures. The study takes place during your single procedure visit.
