Maastricht, LimburgAges 16 years+ - 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 - 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 - NCT05236153Recruiting
Study of heart valve procedure in repaired Tetralogy of Fallot
This study looks at how a transcatheter pulmonary valve replacement works in people with repaired Tetralogy of Fallot or double outlet right ventricle. The goal is to better understand the heart’s anatomy and how it may affect the valve procedure.
Boston, MassachusettsAges Any age - NCT05337241Recruiting
Saline enhanced needle ablation for stubborn heart rhythm
This trial studies a special “needle” ablation method (with saline) to treat a dangerous, repeat heart rhythm problem called monomorphic ventricular tachycardia (VT). It’s for adults whose VT keeps coming back despite prior treatments and who may not benefit from another standard ablation.
Birmingham, AlabamaAges 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+ - 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+ - 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+ - 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 - 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 - 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 - NCT05741112Recruiting
Long COVID wearable study to track symptoms and help daily management
This study uses a wearable device to track symptoms and patterns in people with Long COVID, ME/CFS, and/or POTS. The goal is to see how wearable feedback and tracking tools may help you manage your symptoms.
La Jolla, CaliforniaAges 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 - NCT05835791Recruiting
Study of new ventricular arrhythmia patients getting ICD follow-up
This study looks at people who are newly diagnosed with a dangerous heart rhythm called ventricular tachycardia (VT) and who are getting an implantable cardioverter-defibrillator (ICD). It may help improve how patients are followed in the ICD clinic after the initial hospitalization.
Vancouver, British ColumbiaAges 18 years+ - 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+ - 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 - 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 - NCT05964660Recruiting
Ultrasound-guided imaging for heart rhythm ablation planning
This trial tests a way to use heart ultrasound images together with other heart scans to better plan catheter ablation for dangerous heart rhythm problems. It may help doctors identify the right target areas in the heart before you have the procedure.
Lübeck, Schleswig-HolsteinAges 18–100 - 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.

Common questions
- Are there clinical trials for tachycardia?
- Yes. Clin2 currently lists 127 recruiting tachycardia studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a tachycardia trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a tachycardia trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
