Key result
Dual AV nodal physiology underlies ~27% of pseudo-pacemaker syndrome cases, most commonly presenting with palpitations.
Why the study?
Pseudo-pacemaker syndrome is a rare complication of first-degree AV block causing AV dyssynchrony and hemodynamic symptoms without an implanted pacemaker, requiring better clinical understanding.
Population
17 cases of pseudo-pacemaker syndrome from 14 articles, mostly middle-aged and young adults with average age 47 years
Design
Narrative review including a unique case report and systematic literature search

Etiology classification may aid PPMS evaluation; leaves open prospective validation of tailored management.
Pseudo-pacemaker syndrome is a rare complication of first-degree AV block with four main etiologies, requiring patient-tailored management based on the specific cause.
Feliz et al. (2023) conducted a review in Pseudo-pacemaker syndrome (n=17). Pseudo-pacemaker syndrome was evaluated on Etiologies of pseudo-pacemaker syndrome. A review of 17 cases of pseudo-pacemaker syndrome identified dual AV nodal physiology as the most frequent primary etiology (27%), with palpitations being the most common presenting symptom.
