Supports graded atrial reflex in dogs; extends mechanistic understanding but leaves open human relevance.
Does the extent of atrial receptor stimulation correlate with the magnitude of reflex heart rate increase in anaesthetized dogs?
The magnitude of the reflex increase in heart rate is directly related to the extent of atrial receptor area stimulated.
Kappagoda et al. (1975) studied this question.
