Safe Care for Kids of All Ages With Irregular Heartbeat
When your child’s heart beats too slow, too fast or in disorganized patterns, we can help. The pediatric electrophysiologists at award-winning Nemours Children’s heart centers in Delaware and Florida have specialized training in caring for kids with irregular heartbeat, called arrhythmia.
We detect and treat all types of arrhythmias, like heart palpitations (fluttering), supraventricular tachycardia (when the heart beats too fast) and long QT syndrome (when the heart takes longer than normal to recover between beats).
Our team uses innovative methods to diagnose and treat arrhythmias. We perform catheter-based studies using thin, flexible tubes threaded through blood vessels, and state-of-the-art 3D mapping of the heart’s electrical activity. We may also implant devices like pacemakers, defibrillators and loop recorders. Our team has a strong record of safety and success using these procedures.
We work closely with expert cardiac anesthesiologists, other specialists and highly skilled advanced practice providers and nurses with one common goal — getting your child back to doing what they love.
Two Leading Pediatric Heart Centers
Our heart centers offer highly advanced, integrated care just for kids and young adults with congenital heart disease. Learn about our focused programs, innovative research and exceptional outcomes.
“Nemours Cardiac Center was wonderful. Dr. Temple and the staff were very professional and focused on making sure we had a good experience. We highly recommend Nemours to everyone.”
“Knowing that I had good doctors and nurses to take care of me helped me not feel so alone during the entire process.”
Highly Effective Care With Exceptional Outcomes
Electrophysiologists at Nemours are highly skilled at performing safe, effective procedures for even the most complex arrhythmias and related conditions.

We use the latest technology to precisely locate the source of the arrhythmia and can treat it using fewer, smaller cuts for faster healing.
Our EP lab team has vast expertise. Our experience and cooperative team approach results in better patient outcomes.
We have special expertise in caring for kids with inheritable arrhythmias, or those passed along in families.
Nemours offers everything your child needs within the same system. You get expert arrhythmia care, surgery and long-term condition management in one place.
