Has anyone thought of playing a steady heartbeat at the heart's natural resting frequency with the necessary amplitude for heartbeat entrainment?
We have a lot of work going into the brain but may I direct your attention to two other brains which are not given nearly enough importance! The heart-brain and the gut-brain.

The heart and brain
However, following several years of research, it was observed that, the heart communicates with the brain in ways that significantly affect how we perceive and react to the world. It was found that, the heart seemed to have its own peculiar logic that frequently diverged from the direction of the autonomic nervous system. The heart appeared to be sending meaningful messages to the brain that it not only understood, but also obeyed (Lacey and Lacey, 1978). Later, neurophysiologists discovered a neural pathway and mechanism whereby input from the heart to the brain could inhibit or facilitate the brain’s electrical activity (McCraty, 2002)

The Little Brain In The Gut
The second brain in our stomachs

Our own stomachs may be something of a dark mystery to most of us, but new research is revealing the surprising ways in which our guts exert control over our mood and appetite.
Not many of us get the chance to watch our own stomach's digestion in action.
But along with an audience at London's Science Museum, I recently watched live pictures from my own stomach as the porridge I had eaten for breakfast was churned, broken up, exposed to acid and then pushed out into my small intestine as a creamy mush called chyme.
I had swallowed a miniature camera in the form of a pill that would spend the day travelling through my digestive system, projecting images onto a giant screen.
Its first stop was my stomach, whose complex work is under the control of what's sometimes called "the little brain", a network of neurons that line your stomach and your gut.
Surprisingly, there are over 100 million of these cells in your gut, as many as there are in the head of a cat.

Interesting finding from a groundbreaking paper:
Thomas Schreiber: Measuring Information Transfer (Max Planck Institute for Physics of Complex Systems)
http://arxiv.org/abs...iv:nlin/0001042
As a last example, take a bi-variate time series (see
Fig. 3) of the breath rate and instantaneous heart rate of
a sleeping human suffering from sleep apnea (part of data
set B of the Santa Fe Institute time series contest held in
1991 [6]). Figure 4 shows that while time delayed mutual
information is almost symmetric between both series, the
transfer entropy indicates a stronger flow of information
from the heart rate to the breath rate than vice versa
over a significant range of length scales r. Note that for
small r, the curves deflect down to zero due to the finite
sample size. This result is consistent with the observation
that the patient breathes in bursts which seem to
occur whenever the heart rate crosses some threshold.
Certainly, both signals could instead be responding to a
common external trigger.
So again: Has anyone thought of playing a steady heartbeat at the heart's natural resting frequency with the necessary amplitude for heartbeat entrainment?
