Study Summary

This trial aims to compare continuous beta-blocker use and as-needed rate control of AF in patients with stage II or III heart failure.

Who is the study for?
This trial is for adults with recent atrial fibrillation, a type of irregular heartbeat. They must have an implantable cardiac monitor and be on certain heart rate control medications. Their heart's pumping function should be normal or only slightly reduced, and they may have signs of a condition where the heart is stiff but not enlarged.Check my eligibility
What is being tested?
The study compares continuous use of beta-blockers or calcium channel blockers to using these medications only when needed for controlling heart rate in atrial fibrillation. It uses an implanted monitor to guide treatment and looks at exercise ability, AF episodes, symptoms of heart failure, health markers, and life quality.See study design
What are the potential side effects?
Potential side effects include lower blood pressure, slower heartbeat, dizziness or lightheadedness from beta-blockers; swelling in the feet or legs from calcium channel blockers; fatigue; trouble breathing; and other individual reactions.

Group I: As needed rate controlExperimental Treatment1 Intervention
Patients randomized to the experimental arm will stop their daily beta-blocker and take as needed rate control guided by their implantable cardiac monitor
Group II: ControlActive Control1 Intervention
Patients randomized to the control arm will continue taking their daily beta-blocker for rate control of atrial fibrillation

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Are there any unoccupied roles for participants in this study?

"Affirmative. According to clinicaltrials.gov, the study is actively recruiting patients since it was first uploaded on February 6th 2023 and its most recent edit took place on February 28th 2023. It aims to enrol a total of 20 participants at 1 site."

Answered by AI

Can As needed rate control be administered without risk to patients?

"The safety of As Needed Rate Control is estimated to be a 1 since it is still in its initial phase, with limited evidence for efficacy and safety."

Answered by AI

Could you provide the aggregate number of participants in this experiment?

"Affirmative. As per the clinicaltrial.gov records, this trial is actively searching for 20 patients at a single site which was first listed on February 6th and last updated on February 28th of this year."
