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.

This sounds rather suspicious. To be honest, it sounds like complete
bullshit given the effects (or rather non-effects) of pacemakers and
heart transplants on emotions.
