Does paired atrial pacing improve atrial and ventricular performance in anaesthetized open-chest dogs?
Paired atrial pacing augments both atrial and ventricular hemodynamic performance in a canine model.
Chamberlain et al. (1970) studied this question. Paired atrial pacing in dogs increased atrial contraction force and augmented ventricular performance, resulting in increased cardiac output and elevated systemic arterial pressure.
