Biography

James Daniels, M.D., is a cardiac electrophysiologist at Children’s Health℠ who specializes in evaluating and treating arrhythmias. He is a Professor at UT Southwestern Medical Center.

Everyone’s heart races or feels like it “skips a beat” sometimes, but Dr. Daniels says that what may feel like a cardiac arrhythmia (heart rhythm disorder) may not be. When it is an arrhythmia, though, most aren’t dangerous if the patient lacks any other heart disease, and only a small percentage of arrhythmias are life threatening.

His current research interests include MRI-compatible implantable cardiac devices and atrial fibrillation.

Dr. Daniels earned his medical degree at UT Southwestern Medical Center. He performed both an internal medicine internship and an internal medicine residency at the University of New Mexico Health Sciences Center. He then completed two fellowships at UT Southwestern – one in clinical cardiac electrophysiology and another in cardiovascular diseases.

Dr. Daniels is board-certified in internal medicine, cardiovascular disease and clinical cardiac electrophysiology (the subspecialty focused on the heart’s electrical system). He has published a number of peer-reviewed articles and has delivered several invited lectures related to cardiac arrhythmias.

Dr. Daniels is a member of multiple professional organizations, including the American Heart Association, American College of Cardiology, Heart Rhythm Society, and the American Medical Association.

Dr. Daniels was included in D Magazine's "Best Doctors" list for 2018, 2020-2022.
