Run by Rush University Medical Center · NCT06166277 · Data updated 2026-11-12
This study is tracking how well different treatments work for people under 60 who have ongoing fainting spells and slow heart rates that don't get better with usual care.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are individuals under 60 years old with symptomatic vasovagal syncope or bradyarrhythmia that has not responded to behavioral and medical measures.
✕Probably not a fit
Patients over 60 years old or those with specific heart conditions such as intrinsic sinus node disease or structural heart disease may not benefit from this study.

What this trial studies
The CNA-FWRD Registry is an international prospective observational multicenter registry that focuses on patients experiencing symptomatic vasovagal syncope and bradyarrhythmias. Participants are managed through routine care, which may include medical therapy, radiofrequency catheter ablation of ganglionated plexi, or permanent pacemaker implantation. Eligible patients are under 60 years old and have symptoms that are refractory to standard treatments. The study will track outcomes for those undergoing procedures as well as those in a control group awaiting intervention.
Why it matters
Potential benefit: If successful, this registry could improve treatment strategies for patients suffering from recurrent vasovagal syncope and bradyarrhythmias.
How similar studies have gone: Other studies have shown promise with similar approaches, particularly in the management of vasovagal syncope and bradyarrhythmias.
