NCT ID NCT07445789

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study compares two common heart rate-lowering drugs, verapamil and metoprolol, in 436 adults with paroxysmal atrial fibrillation (AF). It also tests whether using a smartwatch for self-care can reduce hospital visits and improve symptoms. The goal is to find better ways to manage AF and avoid emergency care.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

verapamil or metoprolol

What this could lead to

If successful, this could show that verapamil or smartwatch-guided self-care reduces hospital visits and improves quality of life for people with paroxysmal atrial fibrillation.

What could go wrong

This is a phase 4 trial, so both drugs are already approved, but results may not apply to all AF patients. The smartwatch component depends on patient engagement and may not show clear benefits.
