Registry of Heart Rhythm Fix Procedures Using Pulsed Field Ablation in Poland
This study tracks people who have a procedure called pulsed field ablation to fix an abnormal heart rhythm (atrial arrhythmia). It's a registry, meaning researchers will collect information to learn more about how well the treatment works and how safe it is.
Wroclaw, Lower Silesian VoivodeshipAges 18 years+ - NCT07024927Recruiting
Heart rhythm disorder registry
This study observes people with atrial fibrillation or ventricular tachycardia who are having their first catheter ablation procedure. The goal is to collect information to improve future treatments.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07019519Recruiting
Gut hormones and blood flow in POTS
This study looks at how gut hormones control blood flow after eating in people with POTS. It may help explain symptoms like dizziness and rapid heartbeat after meals.
CopenhagenAges 18–50 - NCT06993038RecruitingPhase 4
Adenosine vs Diltiazem for SVT in the emergency room
This study compares two medications, adenosine and diltiazem, to see which works better for treating a rapid heart rhythm called SVT (supraventricular tachycardia) in the emergency department. If you have a stable episode of SVT, this trial may help doctors find the best treatment for you.
Iowa City, IowaAges 18–100 - NCT05720936Recruiting
Nerve block treatment for dangerous heart rhythm episodes
This trial looks at a procedure called a stellate ganglion block to calm dangerous, repeated heart rhythm attacks that haven’t improved with standard medicines. It may help reduce how often and how long these episodes last while you’re in the hospital.
Alessandria, ALAges Any age - NCT06937983Recruiting
Mapping to guide heart rhythm treatment
This study tests a new way of mapping damaged heart muscle to improve the precision of a procedure called catheter ablation, which treats dangerously fast heart rhythms. It may help people with heart disease who need this procedure.
Coventry, West MidlandsAges 18 years+ - NCT06931821Recruiting
Mapping to guide ablation for ventricular tachycardia
This study tests a new way to map the heart's electrical activity to guide a procedure that destroys the tissue causing fast, dangerous heart rhythms. It's for people with heart disease and ventricular tachycardia that hasn't been controlled by medication.
Phoenix, ArizonaAges 18 years+ - NCT06503016RecruitingPhase 3
