You must have really strong brain waves ;-)
It's from too much lossy thinking.. My brain waves are so strong that
my head overheats from I^2*R losses. I might need to put heat sink on
my head.. :)
I didn't mean the electrodes go on the head but across the heart to
pick up the brain trigger signal. I don't know the dominant signal...
Could be the nerve to the heart.. Could be the heart itself or both.

The myogenic (muscle de/polarization signal) dwarfs neural inputs as
measured from a distance - that is, from the skin. Similarly, active
skeletal muscles have potentials that can make detection of the
heartbeat difficult.
My recent understanding is that the heart triggers itself (an internal
feedback loop).
I dunno if there is a signal from the brain too, but things like adrealine do
affect the speed it runs.
But I am no doctor, so...
When disease or other malady removes neural input, the heart can "free run"
in its absence. Unfortunately, this 'default' rate is slower than what the
CNS would require (and less well controlled for the body's metabolic needs).
