Being told your child has a heart problem, no matter how simple or complex, is overwhelming information for a parent to hear.  

One of my most important roles as a physician caring for patients with heart disease is to educate patients and their families about their condition.  Applying my education and training to help relieve a family’s anxiety in this manner is one of the most fulfilling aspects of my job.

Professional History

Dr. DeWitt completed medical school at Albert Einstein College of Medicine in the Bronx, NY, and then came to the Boston Combined Residency Program at Boston Children’s Hospital and Boston Medical Center, where she completed internship and residency in Pediatrics.  She then stayed on for categorical cardiology fellowship, during which time she served as Chief Fellow. She then completed advanced training in electrophysiology at Boston Children’s Hospital.  Dr. DeWitt is currently a member of the Electrophysiology Division at Boston Children’s Hospital.  She takes care of patients with heart rhythm disorders, in both the inpatient and outpatient settings.  She also performs arrhythmia ablations and pacemaker/ defibrillator and implantable loop recorder implants.   Recent research has focused on the ongoing clinical consequences of ICD therapy, and on initial management strategies in adults with repaired congenital heart disease and atrial tachycardia.  In addition, she has used an animal model to evaluate the physiologic effects of intravenous anti-arrhythmic therapy and inotropic agents on isolated hearts.
