Heart Center for Children at Floating Hospital

Heart Rhythm Program


Compassionate doctors offering world class care

Families find cutting-edge care in a reassuring environment at the Floating Hospital for Children Pediatric Heart Rhythm Program in Boston. The center has the latest, high-tech tools to search out and correct pediatric heart rhythm problems. From ambulatory cardiac monitoring, to exercise stress testing, the best methods for detecting arrhythmias and heart murmurs are used here at Floating Hospital. A full complement of pacemaker and implantable cardiac defibrillator (ICD) services are readily available. Catheter ablations can be performed utilizing either radiofrequency or cryothermal energy, and the most advanced 3-Dimensional mapping systems are used to accurately and safely localize the site of the problem.

Heart arrhythmias, by their very nature, can be a source of extreme anxiety for both parents and children. The specialists and staff at the Heart Rhythm Program are committed to personal, family-centered care. Parents and young cardiac patients can expect their concerns, before and after any procedure, to be addressed and their questions answered in a timely manner.

What to look out for

While some heart rate problems are identified in utero, others may not become apparent until later in childhood and adolescence. Palpitations, shortness of breath, chest pains and dizziness or fainting are possible signs a child may have a heart rhythm issue that needs to be checked out. Even if there are no visible symptoms, parents may want to have their children screened if there is a family history of hereditary conditions which lead to heart rhythm abnormalities. We specialize in treating conditions including Wolff-Parkinson-White Syndrome, Long QT Syndrome, Hypertrophic Cardiomyopathy, Brugada Syndrome, and Arrhythmogenic Right Ventricular Cardiomyopathy, just to name a few.

Meet our director, Alisa Niksch, MD

Dr. Niksch is the director of Floating’s Heart Rhythm Program and an assistant professor at the Tufts University School of Medicine.  She is board certified in pediatrics and pediatric cardiology. Her clinical specialties include cardiac ablation and arrhythmia management, the implanting and management of pacemakers/ICDs and overall management of congenital heart disease. Dr. Niksch is also involved in the development of clinical trials with medical device makers aimed at improving patient care and monitoring.

Expect personal, collaborative care

We understand that cardiac arrhythmias in children cause a tremendous amount of concern within families.  Heart rhythm experts meet directly with patients and their families, taking the time needed to answer all their questions. We are also ready to follow up later by email or phone if needed. We believe it is important for young patients and their parents to understand the patient’s heart rhythm diagnosis and treatment options, and at times, do so by drawing out diagrams and pictures and referring them to reputable websites for further information. Our Heart Rhythm Program also has a close and highly collaborative working relationship with other specialists at Floating Hospital as well as the cardiologists and electrophysiologists serving adult patients at The CardioVascular Center at Tufts Medical Center. This means both better and more efficient care, from the ability to schedule appointments and tests over a single visit to access to some of the top experts in cardiac care.
