Phase 4 — The treatment has already been approved. Researchers are tracking how it works in a large number of people over time.
This trial is testing how two medications— and verapamil—affect irregular heartbeats (premature ventricular contractions, or PVCs) during a heart rhythm procedure called an electrophysiology study. Doctors will give you these medications during your scheduled ablation procedure to see how your heart responds, which may help them understand what's causing your irregular heartbeats and improve future treatment options.
Doctors don't yet fully understand why some people develop these irregular heartbeats. By studying how the medication affects your heart rhythm during your procedure, researchers hope to learn more about what causes PVCs and potentially develop better treatments in the future.

If you join this study, the medications will be given to you during your already-scheduled heart rhythm procedure. Your doctor will first give you verapamil to slow your heart rate, then after the catheters are placed. Your heart's response will be monitored and recorded to help doctors understand your condition. The study also involves analysis of a Holter monitor recording (a portable heart monitor) that you may have had before your procedure as part of your regular care.
