Arrhythmia clinical trials in California
We’re tracking 11 recruiting arrhythmia studies with a site in California — including Phase 4 studies, each written for real people, not researchers.
Recruiting studies in California
- NCT04088071Recruiting
Ablation for heart rhythm problems using a specific technology
This study looks at how well catheter ablation works for treating certain heart rhythm disorders (like atrial fibrillation or ventricular arrhythmias) using a specific brand of catheters. The aim is to gather real-world data to better understand the procedure's outcomes.
Los Angeles, CaliforniaAges 18 years+ - NCT05034432RecruitingPhase 4
Test treatment for dangerous heart rhythm episodes in LVAD patients
This trial studies a procedure to fix abnormal heart rhythms (ventricular tachycardia or ventricular fibrillation) in people who have an LVAD and a defibrillator (ICD) or an alternative device. It may help prevent future dangerous rhythm episodes after LVAD treatment.
Los Angeles, CaliforniaAges 18 years+ - NCT05366361Recruiting
Study of persistent atrial fibrillation during heart procedures
This study looks at what happens in the heart in people with persistent atrial fibrillation when they undergo an ablation or Maze surgery. It may help doctors better understand the condition and improve future care for people needing these procedures.
Stanford, CaliforniaAges 22–80 - NCT05371405Recruiting
Using computer learning to improve care for atrial fibrillation patients
This study uses machine learning (computer pattern-finding) to better understand atrial fibrillation and guide care around the time of an ablation procedure. It may help refine how doctors treat certain AF patients based on their heart patterns.
Stanford, CaliforniaAges 22–80 - NCT06039176Recruiting
Learning from the HeartMate 3 device
This study looks at information from the HeartMate 3 LVAD device to learn more about how it works and what it can tell us about the future. It may help people with advanced heart failure who need this specific device.
San Francisco, CaliforniaAges 18–100 - NCT06100770Recruiting
Aveir leadless pacemaker study for Medicare patients
This study looks at how well a new type of pacemaker, called Aveir AR, works for people with Medicare. It helps doctors understand if this leadless pacemaker is safe and effective for treating slow heart rhythms.
Sylmar, CaliforniaAges 18 years+ - NCT06772493Recruiting
First test of a new ICE ultrasound tool in people
This study is testing a new type of ICE ultrasound tool during heart procedures. The goal is to see how well it works in real people.
La Jolla, CaliforniaAges 18 years+ - NCT07103733Recruiting
Adding MRI and monitoring to mitral valve repair study
This study is for people already in the PRIMARY trial who are having mitral valve repair surgery. It adds an extra MRI scan and possibly a heart rhythm monitor to learn more about heart recovery after repair.
Los Angeles, CaliforniaAges 60 years+ - NCT00271180Recruiting
Tracks long-term performance of Medtronic heart devices
This study follows how well certain Medtronic heart devices work over the long term. You may be included if you have a qualifying Medtronic implant and the research team can reliably get your implant and follow-up information.
Bakersfield, CaliforniaAges Any age - NCT03209583Recruiting
Test of fast-pacing therapy for congenital heart rhythm issues
This trial studies whether a device-based fast pacing therapy (called ATP) can better treat certain rapid heart rhythm problems in people born with a heart condition. It may help prevent or reduce episodes of atrial (upper-chamber) arrhythmias that occur despite having a pacing/defibrillator device.
Orange, CaliforniaAges Any age - NCT04520347Enrolling by invitation
Registry for heart rhythm ablation in VT or PVC
This study is a “registry,” meaning it collects information about people undergoing a procedure to treat abnormal heart rhythms like ventricular tachycardia (VT) or premature ventricular contractions (PVCs). It may help researchers better understand which patients benefit from the procedure and how it is done over time.

What taking part in a arrhythmia study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
Arrhythmia trials in other states
Common questions
- Are there arrhythmia clinical trials in California?
- Yes. We're currently tracking 11 recruiting arrhythmia studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a arrhythmia study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a arrhythmia trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
Not the right time?
New arrhythmia studies open in California regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
Clin2 helps you find and understand clinical trials and does not provide medical advice. Study data comes from ClinicalTrials.gov. Talk with your doctor about whether a specific trial is right for you.
