Dr. Amer Suleman completed his studies at the Ochsner Clinic in New Orleans, the Mid America heart institute, and the Krannert Institute of Cardiology at Indiana University.  Dr. Suleman also held Resident and Clinical Instructor positions at the State University of New York at Buffalo and the Mayo Hospital (in Pakistan).

Dr. Suleman is an established medical lecturer and writer, known for his focus on patient care.  He is Testamur of NASPeXAM in cardiac pacemaker and defibrillator management, and has worked across the state of Texas as Consultant in Cardiac Electrophysiology and Cardiovascular Medicine.

Dr. Suleman is certified in Clinical Cardiac Electrophysiology, Cardiovascular Medicine, Internal Medicine, Pacemakers and Defibrillators, Echocardiography, and as a Specialist in Clinical Hypertension.  He has received numerous awards and grants, and is a regular contributor to the medical and scientific communities.  He has been published widely, and has participated in numerous clinical trials and investigations.

Today, Dr. Suleman and The Heartbeat Clinic serve patients in the Dallas-Ft. Worth areas and beyond.  His main office is in McKinney, Texas.

Svetlana Blitshteyn, MD
Mayo Clinic, Jacksonville

Dr. Blitshteyn graduated from the University at Buffalo with a Bachelor of Science degree in Biochemistry, Summa Cum Laude, and she was the valedictorian of her graduating class.  Dr. Blitshteyn then received her M.D. from the University at Buffalo School of Medicine, where she graduated at the top of her class and was awarded the American Academy of Neurology Student Prize and the Rodenberg Memorial Medal for excellence in the study of diabetes and its complications. 

Following the internship in medicine at the University at Buffalo, she began neurology residency at the Mayo Clinic in Jacksonville, Florida, where she is currently a senior neurology resident. 

Dr. Blitshteyn lives in Jacksonville, Florida with her husband.  Her goal is to practice clinical neurology with a concentration on patients with various types of dysautonomia, and she hopes to contribute to and advance the field of autonomic disorders and treatment through patient care, research and education.

Satish R Raj, MD, MSCI
Vanderbilt University

Satish R Raj grew up in Toronto, Ontario, Canada.  He graduated from Queen’s University Faculty of Medicine in Ontario in 1993.  After completing residency training in Internal Medicine and Cardiology at Queen’s University he moved on to a fellowship in Clinical Cardiac Electrophysiology at the University of Calgary.

In 2002, Dr. Raj moved to Nashville, Tennessee as a Research Fellow in Clinical Pharmacology at Vanderbilt University’s Autonomic Dysfunction Center and completed a Masters of Science in Clinical Investigation. 

He is currently an Assistant Professor of Medicine and Pharmacology at Vanderbilt University and an Attending Physician at the Vanderbilt University Medical Center.

His primary research interests are to understand the cause and find more effective treatments for the postural tachycardia syndrome (POTS) and neurally mediated syncope, as well as disorders of the autonomic nervous system.

Dr. Raj lives with his wife and daughter in the Nashville area.

Julian M. Stewart, MD, PhD
New York Medical College

Dr. Stewart received MD and PhD degrees from the University of Chicago studying cardiac physiology. He is a trained pediatric cardiologist and an integrative physiologist. Dr. Stewart's initial work concerned vascular physiology and was performed in the laboratory of Dr. Thomas Hintze in Physiology at New York Medical College. Subsequently, physiology methods were translated into measurements in conscious humans, largely adolescents and young adults. These are primarily noninvasive adaptations of classical blood flow techniques.

Dr. Stewart's work and funding now centers around understanding the physiology of orthostatic intolerance in young people, its relation to vascular control mechanisms and their impact on the autonomic nervous system. The technological focus has been on the development and use of methods to measure regional blood flow and endothelial function in patients and in healthy volunteers. He has developed methods using a combination of segmental impedance plethysmography, strain gauge plethysmography, ultrasound and laser Doppler flowmetry along with microdialysis techniques in which he can test the responses to drugs and can measure changes in microscopic amounts of biochemicals. These are applied to treatment of OI.
