A Physician Families Can Trust

Dr. Singh is a highly experienced Pediatric Cardiologist who specializes in Pediatric Electrophysiology (the study and treatment of the heart’s electrical system). He has been caring for children with heart conditions for over 19 years. Dr. Singh completed his medical degree and pediatric training in Mumbai, India, along with additional training in newborn care (Neonatology), before moving to the United States. Here, he repeated his pediatric residency, went on to complete a fellowship in Pediatric Cardiology, and received advanced training in Electrophysiology at the Children’s Hospital of Michigan. Over the years, he has served as Chief of Pediatric Cardiology, held leadership positions at major hospitals, and taught future doctors as a Professor of Pediatrics at Case Western Reserve University School of Medicine. He is known for his expertise in caring for children and young adults with heart rhythm problems, including those with congenital heart disease.

Dr. Singh was among the first to perform “fluoroless” EP procedures (without X-ray radiation) in children, helping make treatment safer for young patients. He also has extensive experience with device implantation (such as pacemakers) and advanced techniques to treat abnormal heart rhythms. In addition, Dr. Singh has special expertise in treating patients with disorders of the autonomic nervous system (also called Dysautonomia). For some children with severe symptoms, he offers innovative treatments that can improve quality of life without the need for a pacemaker. Most importantly, Dr. Singh is dedicated to providing compassionate, family-centered care and helping children live healthy, active lives.
