Recruiting studies
- NCT06464315Enrolling by invitation
VT Ablation Guided by Scar Tissue Only
This trial tests a new approach to treating a dangerous heart rhythm called ventricular tachycardia (VT) in people with scarred heart muscle. The goal is to use only the scarred area to guide the ablation procedure, which may make it safer and more effective.
San Diego, CaliforniaAges 18–90 - NCT06255457Recruiting
Heart rhythm study for patients getting mitral valve surgery
This study looks at heart rhythm problems in people having mitral valve surgery to fix a leaky valve. It may help doctors better understand who is at risk for dangerous rhythms.
Stockholm, Stockholm CountyAges 18 years+ - NCT06376916RecruitingPhase 3
Testing magnesium doses for fast heart rate in atrial fibrillation
This trial tests whether giving a higher dose of magnesium (4 grams) compared to a lower dose (2 grams) or a placebo can help control a fast heart rate during atrial fibrillation. It may help patients who are already receiving diltiazem.
Oak Lawn, IllinoisAges 18 years+ - NCT06371729Recruiting
Comparing two heart mapping methods for VT ablation
This trial tests two different ways of mapping the heart to guide treatment for a dangerous fast heart rhythm. The goal is to see which mapping method works better for people with an ICD who need a procedure called ablation to stop the rhythm.
Milan, LombardyAges 18 years+ - NCT04075084Recruiting
Watching outcomes of routine home monitoring after a heart monitor implant
This registry study follows people who get a BIOTRONIK implantable heart monitor and use home monitoring. It looks at how routine care and at-home check-ins work in real life, which may help improve support and tracking over time.
AdelaideAges 18 years+ - NCT06128980RecruitingPhase 2/Phase 3
Stopping heart meds after recovery from fast heartbeat damage
This trial tests if patients whose heart function returned to normal after treating a fast heartbeat can safely stop their heart failure medications. It aims to see if treatment can be withdrawn without the heart problems coming back.
CopenhagenAges 18 years+ - NCT05377216RecruitingEarly Phase 1
Testing nerve stimulation effects during heart ablation
This trial studies how a type of nerve stimulation affects the heart’s electrical signals during a procedure to treat a dangerous fast heart rhythm (ventricular tachycardia). It may help doctors better understand safety and effects during planned ablation.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05924646Recruiting
Testing salt to treat POTS symptoms
This study looks at whether adding salt helps improve POTS symptoms, especially the fast heart rate that happens when you stand. You’d be screened carefully to make sure your symptoms fit POTS and that other causes of fast heart rate are unlikely.
Calgary, AlbertaAges 18–60 - NCT05914649Recruiting
Testing long COVID and POTS brain fog symptoms
This study tests how different long-COVID and POTS-related symptoms—especially “brain fog”—show up and improve. It may help researchers better measure symptoms so future treatments can be targeted more effectively.
Calgary, AlbertaAges 18–60 - NCT05841199Recruiting
Study heart blood flow during fast heart rates
This study measures how well blood flows through the heart when the heart rate is increased during a heart procedure. It may help doctors better understand coronary (heart artery) blood flow and how to guide treatment when you need angiography or angioplasty.
LondonAges 18 years+ - NCT05763953RecruitingPhase 2
Nasal medicine trial for fast heart rhythm in children
This Phase 2 trial tests whether an at-home nasal spray medicine called etripamil can help children who have episodes of a specific type of fast, irregular rhythm caused by an electrical “AV node” circuit. It mainly targets certain kids with past or confirmed episodes on heart testing.
Phoenix, ArizonaAges 6–17 - NCT05705297Enrolling by invitation
Ultrasound-guided heart procedure to treat a fast rhythm
This trial tests a way to stop a specific fast heart rhythm (AVNRT) using a freezing treatment guided by an ultrasound camera inside the heart. It may help people whose heart rhythm episodes come from a “slow pathway” wiring circuit.
LjubljanaAges 4–80 - NCT05599022Recruiting
Testing TcMS to stop dangerous fast heart rhythms
This trial tests a treatment called TcMS to reduce episodes of dangerous fast heart rhythm (VT) or shocks from an implanted heart device. It may help people who keep having these episodes even after taking at least one anti-arrhythmia medicine.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05618054Recruiting
Explaining nerve signals in teens with POTS
This study looks at how a specific brain–vagus nerve connection works in people with POTS and tries to understand what happens over time. It may help researchers better explain symptoms and other health problems that can occur with POTS.
Richmond, VirginiaAges 12–21 - NCT05633693Recruiting
Exercises to help children with fainting and blood-pressure drops
This study tests whether teaching special standing/balance movements can reduce fainting episodes in children who have recurring vasovagal fainting or certain forms of POTS. It may help your child feel more stable when standing and improve symptoms, while researchers measure balance and “counterpressure” responses during the tests.
Burnaby, British ColumbiaAges 6–18 - NCT05555771Recruiting
Kids with fainting episodes after arriving at the emergency room
This study looks at children and teens (ages 6–18) who recently fainted but are now back to normal, using a survey. It aims to better understand fainting episodes that happen before the emergency visit and how to evaluate them safely.
Vancouver, British ColumbiaAges 6–18 - NCT05543798Recruiting
MRI-guided heart procedure for dangerous abnormal rhythms
This trial studies a heart rhythm procedure (“ablation”) for people with ischemic cardiomyopathy who have ongoing episodes of sustained ventricular tachycardia. It aims to reduce these dangerous rhythm events, especially when standard anti-rhythm medications don’t work or can’t be used.
Leipzig, SaxonyAges 18 years+ - NCT05439031RecruitingPhase 2
Stereotactic radiation to reduce recurrent dangerous heart rhythm episodes
This Phase 2 study tests a precise form of radiation therapy to control recurrent ventricular tachycardia (VT), a dangerous fast heart rhythm. It may help people whose VT keeps coming back despite heart medicines and/or ablation, especially when ablation is not possible.
Amsterdam, North HollandAges 18 years+ - NCT05212129Recruiting
Stimulation of the ear nerve to help gut symptoms
This study tests whether stimulating a nerve in the ear (called auricular vagal nerve stimulation) can improve upper gut symptoms in teens who may have hypermobile Ehlers-Danlos syndrome (hEDS) or hypermobile spectrum disorder (HSD). It also checks whether this treatment helps nerves that control the body (autonomic nervous system) and how well the gut moves.
Milwaukee, WisconsinAges 10–18 - NCT05014802Recruiting
MRI scans before heart surgery to predict post-surgery atrial fibrillation
This study uses an MRI scan before heart surgery to look for heart scarring that may predict who will develop atrial fibrillation afterward. Knowing the risk ahead of time could help doctors monitor you more closely and plan prevention.
Covington, LouisianaAges 40–120 - NCT04881318Recruiting
Compression garments for POTS symptoms at home
This study tests whether wearing waist-high compression garments in everyday life can reduce symptoms for people with POTS. You’ll take part over a 4-day period and compare different days with a washout period in between.
Calgary, AlbertaAges 18–60 - NCT04806620Recruiting
Online app study for brain inflammation lifestyle data
This study uses a digital platform (app/website) to collect lifestyle and symptom information to better understand brain inflammation. You may qualify if you have certain conditions like Long COVID, migraines, autoimmune disease, inflammatory gut issues, mood disorders, or if you are a healthy comparison person.
Delafield, WisconsinAges 2 years+ - NCT04499326Recruiting
Improve quality-of-life reporting after defibrillator heart ablation
This study looks at how to better track patients’ quality of life (how you feel and function) after catheter ablation for a dangerous heart rhythm, using questionnaires you complete. It may help the care team understand how to measure patient outcomes more accurately after treatment.
LondonAges 18 years+ - NCT04162171Recruiting
SBRT treatment study for steady heart rhythm VT
This study looks at using SBRT (high-precision radiation) to treat a dangerous, steady heart rhythm called monomorphic VT. It is meant for people who keep having VT even after prior ablation attempts and after trying a class III “rhythm-stabilizing” medicine.
