• 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

• Bachmann bundle versus right atrial appendage pacing in sick sinus syndrome

  This research tests whether pacing the Bachmann bundle instead of the right atrial appendage reduces atrial structural and functional damage in people with sick sinus syndrome who are getting a permanent pacemaker.

  Recruiting Samsung Medical Center · Seoul, Seoul · NCT07360067

• Left bundle branch area pacing versus minimized ventricular pacing for sick sinus syndrome with a prolonged PR interval

  This test compares left bundle branch area pacing with minimized ventricular pacing to see which works better for adults with sick sinus syndrome and a long AV (PR) interval.

  Recruiting Asan Medical Center · Seoul, Songpa-gu · NCT07314008

• Using 5G technology for follow-up care of heart devices

  This study is testing if using 5G technology for remote check-ups can be as safe and effective as regular in-person visits for people with heart devices like pacemakers and defibrillators.

  Recruiting at 2 sites The Third People's Hospital of Chengdu · Guangzhou, Guangdong and 1 other locations · NCT06652750

• Cardioneuroablation for treating bradycardia

  This study is testing a new procedure called cardioneuroablation to see if it can help people with slow heart rates feel better without needing a permanent pacemaker.

  Recruiting Federal State Budgetary Institution, V. A. Almazov Federal North-West Medical Research Centre, of the Ministry of Health · Saint Petersburg · NCT06288633
