Comparing two heart medicines for fast, irregular heartbeat
Part of Heart & circulation clinical trials.
This study compares two medications, verapamil and metoprolol, given in the emergency department to slow down a fast, irregular heartbeat caused by atrial fibrillation. It aims to find which medicine works better and is safer for patients like you.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older and are in the emergency department.
- You have been diagnosed with atrial fibrillation with a fast heart rate (at least 110 beats per minute).
- Your blood pressure is stable (systolic at least 90 mmHg) and you are not in shock or fluid in the lungs.
- You are not currently taking medicines to control your heart rate (like beta-blockers, calcium channel blockers, or digoxin) in the last 24 hours.
- You do not have severe heart failure, a very weak heart pump (ejection fraction less than 30%), or certain heart rhythm problems.
- You are not pregnant or breastfeeding, and you can give written consent.

This trial tests two medicines — one taken by mouth (bisoprolol) and one given through an IV (diltiazem) — to see which is better at safely slowing a too-fast heartbeat in people with atrial fibrillation or flutter. If you have this heart rhythm problem with a fast rate and are otherwise stable, the study might help find the most effective way to bring your heart under control.
This trial compares two medications that control heart rate, verapamil and metoprolol, taken only when you feel an episode of paroxysmal atrial fibrillation (short, irregular heartbeats). It also tests a smartphone app that helps you manage your condition. The goal is to see if this approach improves symptoms and reduces episodes.
This study compares different heart rate targets for people with ongoing atrial fibrillation (an irregular heartbeat) to find which one improves symptoms and quality of life. It may help you and your doctor choose the best treatment plan.
This trial tests whether starting treatment early to control your heart's rhythm can help people with a heart device who have short bursts of a fast heartbeat (called atrial high rate episodes) but haven't yet been diagnosed with atrial fibrillation on a standard EKG or Holter monitor.
This study compares two procedures for people who have both atrial fibrillation (AFib) and heart failure: one that slows the heart's electrical signals (AV node ablation) and one that helps the heart pump in a more coordinated way (cardiac resynchronization). Both are options when medications alone aren't enough, and the goal is to improve symptoms and quality of life.
This study compares two different treatment strategies for atrial fibrillation (an irregular heartbeat) in people who also have heart failure. One strategy uses medications only, while the other includes a procedure to restore normal heart rhythm. The goal is to find the best way to improve symptoms and outcomes.
