All recruiting trials (12)

• Transjugular implantation of a leadless pacemaker (Aveir VR) for ventricular pacing

  This study tests whether placing an Aveir VR leadless pacemaker through the neck vein can safely provide ventricular pacing in adults with bradycardia.

  Recruiting Xijing Hospital · Xi'an, Shaanxi · NCT07802119

• Focal Cryoablation vs. Radiofrequency Cardioneuroablation for Bradyarrhythmias

  This study tests whether focal cryoablation can treat vagally driven slow heart rhythms as well as traditional radiofrequency ablation in adults with bradycardia or related syncope.

  Recruiting Tomsk National Research Medical Center of the Russian Academy of Sciences · Tomsk, Tomsk Oblast · NCT07671898

• Left bundle area pacing with Closed Loop Stimulation in dual‑chamber pacemakers

  This study tests whether a dual‑chamber pacemaker using left bundle area pacing and Closed Loop Stimulation can reduce device‑detected atrial fibrillation over 24 months in patients with sinus node disease and AV conduction issues.

  Recruiting Biotronik SE & Co. KG · Ústí nad Labem and 11 other locations · NCT07608822

• Remote ECG monitoring after TAVI

  This compares continuous 30-day remote ECG monitoring to standard short-term monitoring for adults after TAVI to see if it detects rhythm problems earlier.

  Recruiting at 3 sites Medical University of Silesia · Turin and 3 other locations · NCT07521800

• Conduction system pacing vs. traditional pacing in adults with atrioventricular block

  This study tests whether stimulating the heart’s conduction system can reduce heart failure events for adults needing pacemakers due to AV block.

  Recruiting at 2 sites IRCCS Azienda Ospedaliero-Universitaria di Bologna · Bari and 13 other locations · NCT07279870

• Comparing two pacemaker pacing methods for AV block

  This trial tests whether conduction system (left bundle branch area) pacing or standard right ventricular pacing works better for people with atrioventricular block who need a permanent pacemaker.

  Recruiting at 2 sites University of Tartu · Tallinn, Harju and 1 other locations · NCT07276490

• Left bundle branch pacing versus right ventricular pacing to reduce device‑detected fast atrial episodes in people with preserved ejection fraction

  This trial will test whether left bundle branch pacing (LBBP) reduces the total time people with preserved ejection fraction spend in device‑detected fast atrial episodes compared with standard right ventricular pacing.

  Recruiting University Hospital of Patras · Pátrai · NCT07250529

• Left bundle branch area pacing versus conventional right‑ventricular pacing after TAVI for atrioventricular block

  This will test whether left bundle branch area pacing works better than standard right‑ventricular pacing for people who need a pacemaker after TAVI.

  Recruiting at 6 sites Nantes University Hospital · Brest, Finistère and 6 other locations · NCT07236489

• Evaluating different approaches to cardiac pacing in patients

  This study is testing different ways to place pacemakers in adults to see which methods work best and are safest for patients needing heart support.

  Recruiting at 31 sites University Hospital of Ferrara · Ferrara, FE and 30 other locations · NCT06324682

• Left Bundle Branch Area Pacing vs Right Ventricular Pacing for Atrial Fibrillation Risk in AV Block

  This study tests whether left bundle branch area pacing can lower the chance of developing atrial fibrillation compared with traditional right ventricular pacing in adults with AV block.

  Recruiting Peking Union Medical College Hospital · Beijing, Beijing Municipality · NCT06023784

• Comparing pacemaker implantation and cardioneuroablation for treating atrioventricular block

  This study is testing whether a new treatment called cardioneuroablation is as safe and effective as traditional pacemaker implantation for people aged 18-75 with atrioventricular block.

  Recruiting at 2 sites American Heart of Poland · Dąbrowa Górnicza and 1 other locations · NCT05774262

• Comparing Left Bundle Branch Area Pacing to Right Ventricular Pacing in Heart Patients

  This study is testing whether pacing the heart from the left side works better than pacing from the right side for people with slow heartbeats who need help with their heart rhythm.

  Recruiting at 7 sites Yonsei University · Bucheon-si and 7 other locations · NCT05585411

NIH-funded research (2)

Early-stage science funded by the US National Institutes of Health. Most of these projects don't enroll patients, but they show what is being worked on.

• A treatment to prevent heart block in babies by blocking IgG recycling during pregnancy

  A new approach aims to protect unborn babies from heart damage by using Rozanolixizumab to lower harmful antibodies that can cross from mother to fetus.

  NIH research New York University School of Medicine · New York, United States · NIH-11417266

• Preventing fetal heart block through early monitoring and treatment

  This study is looking at how to help prevent serious heart problems in unborn babies by having expectant moms check their baby's heart rate every day, so they can catch any issues early and get the right treatment in time.

Quick answers

How many Atrioventricular Block clinical trials are recruiting right now?

12, as of November 12, 2026. We update this list each time we refresh our data from ClinicalTrials.gov.

Where are these trials running?

In 12 countries. The most sites are in Italy (4 trials), China (2 trials), Poland (2 trials), Greece (1 trial), Estonia (1 trial). Each study page lists its sites and which ones are recruiting.

How do I join one?

Open a study, check the "Is this trial a fit for you?" section, then contact the study team listed on the page. They will ask a few screening questions. Asking is free and does not commit you to anything. Talk it over with your doctor first.
