Implication

May guide vagal timing in canine models; leaves open translation to human neuromodulation or arrhythmia therapies.

Structured PICO

Does the timing of repetitive vagal stimulation affect atrial contraction in anesthetized dogs?

P
Population
Anesthetized dogs
I
Intervention
Repetitive vagal stimulation (brief burst of pulses once each cardiac cycle with varying timing)
O
Outcome
Atrial contraction (inotropic effect)surrogate

The timing of vagal stimulation within the cardiac cycle significantly influences its negative inotropic effect on atrial contraction in dogs, suggesting rapid acetylcholine hydrolysis and phase-dependent sensitivity.
