Overview

Highlights timing-dependent autonomic effects on AV conduction in animals; hypothesis-generating and requires human validation before clinical relevance.

Structured PICO

P
Population
Anesthetized open-chest mongrel dogs
I
Intervention
Short bursts of vagal stimulation placed in various portions of the cardiac cycle and stellate ganglia stimulation
O
Outcome
Atrioventricular conduction timessurrogate

Autonomic neurotransmitters differentially affect cardiac conduction times depending on the timing of vagal stimulation within the cardiac cycle.
