Heart Rate Variability (HRV) is used by some of the most prominent physicians. We are not so much interested in the heart, but rather the neurological control of the heart. We use the heart electricity because it is simple and convenient to measure. Similar neurological impulses are found in the intestinal track, brain and other organs but they are not as easy to measure.

The autonomic (automatic) nervous system has two parts. The easiest way to explain this is to think of an automatic car. The Sympathetic nervous system is like the accelerator. The Parasympathetic nervous system is like the brake. In order for the car to function properly both are required. There are many examples within the human body. There are nerves that open your eyes and equal and opposite nerves that close your eyes. When you start to walk there are one set of nerve impulses, the opposite nerve impulses allow you to stop walking. The digestive system is another example one set of nerve impulses start digestion and equal and opposite nerve impulses stop digestion.

HRV measures both of these, and for optimal health (just like the car) the two need to be in balance. In some cultures this balance is known as the Yin and the Yang. In my clinical experience, measuring the parasympathetic healing energy helps me come up with the best treatment plan.
