Implication

Lower dual AV nodal pathway prevalence in older patients may underlie reduced AVNRT incidence; extends age-related EP observations but remains hypothesis-generating.

Structured PICO

Does the incidence of dual AV nodal pathways decrease with age in patients undergoing transoesophageal electrophysiological study?

Population

159 patients referred for transoesophageal electrophysiological study for syncope (8.2%), suspected ventricular pre-excitation (10.7%), suspected sinus node dysfunction (52.8%) or undetermined palpitations (28.3%). Excluded: patients with a diagnosis of ventricular pre-excitation, supraventricular arrhythmia or AV block.

Intervention

Transoesophageal electrophysiological study with premature atrial stimulation

Comparator

Comparison across age groups: group A (11-30 years), group B (30-60 years), and group C (>60 years)

Outcome

Incidence of dual atrioventricular (AV) nodal pathwayssurrogate

The incidence of dual AV nodal pathways decreases significantly with age, which may explain the lower frequency of AV nodal re-entrant tachycardia in the elderly.
