Testing BAY 3670549 for Recent-Onset Atrial Fibrillation
This study tests a new drug called BAY 3670549 to see if it can help convert atrial fibrillation (an irregular heartbeat) back to normal rhythm. You'll receive the study drug or a placebo along with a procedure to restore your heart's normal rhythm, and researchers will monitor how well it works and how safe it is.
San Francisco, CaliforniaAges 18–85 - NCT07626411RecruitingPhase 3
Blood Thinner Study for Irregular Heartbeat
This study tests a new blood thinner to prevent strokes and blood clots in people with atrial fibrillation (a common heart rhythm problem). You may qualify if you have atrial fibrillation and at least one risk factor for stroke, or if you've never taken a blood thinner before.
Alexander City, AlabamaAges 18 years+ - NCT07610980Recruiting
Finding the best shock strength for atrial fibrillation treatment
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.
PragueAges 18 years+ - NCT07582523Enrolling by invitation
Heart Rhythm Monitoring at Home for High Blood Pressure
This study tests whether wearing a small heart rhythm patch at home can detect irregular heartbeats in people with high blood pressure. It may help catch heart rhythm problems early before they cause symptoms.
San Francisco, CaliforniaAges 60 years+ - NCT07575269Recruiting
New ablation treatment for irregular heartbeat
This trial tests a new tool called FARAFLEX that uses pulsed electrical energy to treat atrial fibrillation (an irregular heart rhythm). The goal is to see if this method can safely stop AF symptoms in people whose medications haven't worked.
Jonesboro, ArkansasAges 18 years+ - NCT07563257Recruiting
Comparing Two Mapping Catheters for Heart Rhythm Ablation
This trial compares two types of specialized catheters used during heart rhythm ablation procedures to help doctors confirm they've created the right burn patterns. If you're having ablation for persistent atrial fibrillation or flutter with complex burn lines planned, this trial may help improve how your procedure is done.
Be’er Ya‘aqovAges 18 years+ - NCT07501299Recruiting
HeartBeam ECG Registry for heart monitoring
This registry collects ECG data from people who are already getting an ECG for their heart health. It uses a device called HeartBeam to see if it works as well as the standard ECG machine.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT06245187Recruiting
Atrial Fibrillation In-Hospital Registry
This registry study collects information on people hospitalized for atrial fibrillation or atrial flutter (types of irregular heartbeats) to help doctors learn how to improve care. By joining, you help researchers understand what treatments work best.
Dallas, TexasAges 18–125 - NCT07447297Recruiting
Early Rhythm Control for Device-Detected Fast Heart Episodes
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.
Seoul, SeoulAges 19 years+ - NCT06157437Recruiting
Focal pulse ablation for atrial flutter
This study tests a new device that uses focused pulses of energy to treat a common type of fast heartbeat called typical atrial flutter. It aims to see if this approach is safe and effective for people who have had at least one episode in the past 6 months.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07407790Recruiting
Smartphone heart check after stroke
This study tests whether using a smartphone app to check your heart rhythm after a stroke can find hidden atrial fibrillation (an irregular heartbeat). If you had a recent stroke or TIA and are not already on blood thinners, you may be able to help doctors detect and prevent future strokes.
KristiansandAges 18 years+ - NCT07362134Enrolling by invitation
Pulsed-field ablation for recurrent atypical atrial flutter
This study tests a new type of energy called pulsed-field ablation (PFA) to treat a specific kind of irregular heartbeat called atypical atrial flutter that keeps coming back after a prior ablation. It aims to see if this approach can safely stop the abnormal rhythm.
