Huh? Any sources for this? The Purkinje fibers are muscle fibers that also act as signal transductors, using gap junctions to send signals quickly but not act as switches. The electrical of the activity is also very simple.

Que? What is the evidence for this? As far as I remember, it is not connected to anything by the vagus nerve and sympathetic nervous system, and I haven't heard of any efferent connections from the heart.
