Testing heart shock to understand atrial fibrillation and heart failure symptoms
Part of Heart & circulation clinical trials.
This trial tests whether a procedure called electrical cardioversion (a controlled shock to reset your heart rhythm) can help explain and possibly improve symptoms of atrial fibrillation and heart failure. If you qualify, you'll receive this procedure and your symptoms will be closely monitored.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have had heart failure for at least 3 months and symptoms like shortness of breath or fatigue (NYHA class 2 or higher) despite treatment.
- You currently have atrial fibrillation or flutter confirmed by an ECG.
- You have been taking blood thinners (such as apixaban, rivaroxaban, or warfarin) for at least 3 weeks.
- You have not been hospitalized for worsening heart failure in the last 3 months.
- You have not had a heart attack, stroke, or major heart procedure in the last 3 months.

This trial tests a special defibrillation technique that uses two shocks to reset the heart's rhythm in people with persistent atrial fibrillation. It aims to help patients regain a normal heartbeat without the need for more invasive procedures.
This study tests whether giving the medicine amiodarone before a scheduled electrical cardioversion (a procedure that shocks the heart back into rhythm) improves the chances of restoring a normal heartbeat in people with persistent atrial fibrillation. It compares outcomes with and without this pre-treatment.
This study tests whether doing a short cycling exercise right before a heart shock procedure (called electrical cardioversion) can make the procedure more effective at restoring a normal heartbeat. If successful, it could simplify treatment for people with persistent atrial fibrillation.
This trial compares a procedure called ablation (using cold, heat, or electric pulses to fix irregular heartbeats) with standard medications to see which better treats heart failure in people who also have atrial fibrillation. It may help if your heart's pumping ability is reduced and you still have symptoms despite medications.
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.
This study compares different shock energy levels to find the most effective and safe way to reset an irregular heartbeat (atrial fibrillation) back to normal rhythm using a procedure called electrical cardioversion.
