Nicholas L. DePace
MD, FACC
Autonomic dysfunction, also known as Dysautonomia has been an area of interest for Dr. DePace.
The autonomic nervous system is the part of the body that controls the things that one does not normally think of. These are involuntary actions such as digestion, breathing, and heart beating.
Abnormalities of autonomic function can cause disabling symptoms and impair one’s quality of life and, when they become severe and disrupt the cardiac autonomic system, can actually be life-threatening.
Approximately 15 years ago, Dr. DePace himself, suffered from abnormalities of dysautonomia when he had recurrent fainting episodes which did not improve over six months. He also had chronic fatigue which he, eventually, was able to get over. He then began to research autonomic dysfunction niche in detail.
Author of A Text Book On Autonomic Dysfunction
Co-written along with Dr. Joseph Colombo, Clinical Autonomic Dysfunction, by Springer Publishers, (measurement, indications, therapies, and outcomes) was published in 2015.
It is the only textbook of its type on autonomic dysfunction and is written predominantly for medical physicians and doctors but can be used by physiologists, nurses, and other health care professionals and established him as one of the prominent autonomic dysfunction doctors.
Dr. Nicholas L. DePace is also a noninvasive cardiologist who specializes in valvular heart disease management and coronary artery disease prevention and reversal (regression). He also specializes in the treatment of autonomic functions. He has been practicing cardiology since 1983 and has published leading articles in the field along with co-authoring the book, The Heart Repair Manual. Dr. DePace tries to treat his patients holistically, naturally, and medically and when possible, tries to avoid bypass and other invasive procedures.
