Key result
Spontaneous activity of canine ventricular neurons was correlated with the cardiac cycle in 81% and the respiratory cycle in 17% of identified neurons.
Canine ventricular neurons exhibit spontaneous activity linked to cardiovascular and respiratory dynamics and are modulated by autonomic efferents and cardiac mechanoreceptors.

Should not yet inform clinical practice; leaves open functional roles of intrinsic cardiac ganglia in humans.
Armour et al. (1990) studied this question. Observation of spontaneous neuronal activity was evaluated on Correlation of spontaneous neuronal activity with cardiac and respiratory cycles. Spontaneous activity of canine ventricular neurons was correlated with the cardiac cycle in 81% and the respiratory cycle in 17% of identified neurons.
