This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing pulsed field energy as a newer way to treat paroxysmal atrial fibrillation (a condition where your heart's rhythm becomes irregular and then returns to normal on its own). Researchers want to see if this new energy method works better than the traditional radiofrequency energy that doctors have used for years, and whether combining both methods might be even more effective. The trial will track how well the treatment works and measure specific signals that show how it affects the nerve that controls your heart rate.
Paroxysmal atrial fibrillation can cause serious complications, and while traditional treatments exist, doctors are looking for better options that might work more effectively with fewer side effects. This trial is designed to see whether this newer energy approach could improve outcomes for patients dealing with this condition.

You will be randomly assigned to receive one of three ablation procedures: using only the new pulsed field energy, using a combination of both energies, or using only the traditional radiofrequency energy. The procedure itself is an outpatient treatment where doctors place a catheter in your heart to isolate the veins causing the irregular rhythm. You'll have blood tests and heart rhythm monitoring before the procedure, 20 minutes after, and again 24 hours later, then follow-up visits at 3, 6, and 12 months with heart rhythm recordings to see how well the treatment is working.
