Why the study?
Because cardioneuroablation involves parasympathetic denervation, inappropriate sinus tachycardia may be an underappreciated potential adverse effect.
Does cardioneuroablation cause inappropriate sinus tachycardia in patients with reflex syncope?
Design
Case report and literature review
Key result
Cardioneuroablation for reflex syncope in an 18-year-old female resulted in intractable inappropriate sinus tachycardia, ultimately requiring sinus node modification and pacemaker implantation.

Does cardioneuroablation cause inappropriate sinus tachycardia in patients with reflex syncope?
Cardioneuroablation for reflex syncope can lead to inappropriate sinus tachycardia as an adverse effect, potentially requiring pacemaker implantation.
Kułakowski et al. (2025) conducted a case report in Reflex syncope and functional bradycardia (n=1). Cardioneuroablation (CNA) was evaluated. Cardioneuroablation for reflex syncope in an 18-year-old female resulted in intractable inappropriate sinus tachycardia, ultimately requiring sinus node modification and pacemaker implantation.
