If your child has been diagnosed with an arrhythmia, or an abnormal heart rhythm, you’re likely to be concerned. The NewYork-Presbyterian Arrhythmia Management and Electrophysiology Service is dedicated to diagnosing and treating heart rhythm disorders in children and adolescents. Our experienced pediatric electrophysiologists care for children with a wide range of arrhythmias, from those with occasional episodes of palpitations to patients with complex cardiac arrhythmias, including heart rhythm problems after open-heart surgery. Using the latest diagnostic and therapeutic approaches, we customize a plan of care to give your child the best chance for a long, healthy, and productive life.
About our program
The Arrhythmia Management & Electrophysiology Service, operating across NewYork-Presbyterian Morgan Stanley Children’s Hospital and NewYork-Presbyterian Komansky Children's Hospital, is one of the largest programs of its kind in the New York metropolitan region. Our expert pediatric electrophysiologists provide comprehensive, compassionate, multidisciplinary care to young patients with arrhythmias. We begin with diagnostic testing to determine the type and location of the abnormal heart rhythm. Armed with that knowledge, we tailor a customized treatment plan for your child using medication, ablation, the implantation of a pacemaker or other devices to restore a normal rhythm to your child's heart. With timely diagnosis and the right treatment, children with arrhythmias lead full and active lives.
What is an arrhythmia?
An arrhythmia is a problem with the rate or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slowly, or with an irregular rhythm. When a heart beats too fast, the condition is called tachycardia. When a heart beats too slowly, the condition is called bradycardia.
Arrhythmias may occur at any age, although the condition is far more common in adults.
Symptoms of arrhythmia in children
Children with arrhythmias often experience no symptoms, or they can’t express the problem. Often, an arrhythmia is discovered as part of a child’s physical exam, or through another encounter with your child’s pediatrician.
Symptoms of arrhythmia may include:
- Heart palpitations
- Lightheadedness or dizziness
- Low blood pressure
- Syncope (fainting or temporary loss of consciousness)
- Difficulty feeding (in infants)
- Slow heartbeat
- Fast heartbeat
- Heartbeat that skips
Types of arrhythmias we treat
At NewYork-Presbyterian, we treat a full range of heart rhythm disorders in children and adolescents, including:
- Arrhythmias after surgery for congenital heart disease
- Arrhythmias related to hypertrophic and dilated cardiomyopathy
- Brugada syndrome
- Catecholoaminergic polymorphic ventricular tachycardia
- Fetal arrhythmias
- Heart block
- Hypertrophic and dilated cardiomyopathy
- Long and short QT syndrome
- Supraventricular tachycardia
- Ventricular tachycardia
- Wolff-Parkinson-White syndrome
How we diagnose arrhythmias
To diagnose your child’s arrhythmia, our physicians may ask you about your medical and family history, which can help establish your child’s risk for arrhythmia. In addition to invasive electrophysiologic studies, our team performs non-invasive diagnostic procedures in children with palpitations or syncope (fainting or temporary loss of consciousness). These procedures include:
- Electrocardiograms (EKG or ECG)
- 24-hour Holter monitoring
- Event recording
- Stress testing
How we treat arrhythmias
Some children's arrhythmias respond to treatment with medications. We may need to try different drugs before we identify which medication works best for your child.
Interventional therapies such as ablation procedures can effectively treat and often permanently cure arrhythmias by eliminating the cause of the abnormal rhythm.
- During an ablation procedure, which we perform in a pediatric catheterization lab, our pediatric electrophysiologist inserts catheters into the child's veins via the groin and advances them toward the heart. The catheters electrically stimulate the heart to induce the abnormal rhythm that has been causing the child's symptoms.
- The pediatric electrophysiologist interprets the rhythm, and then delivers energy via the catheter, using either radiofrequency energy or cryotherapy (freezing temperatures). These therapies eliminate the cause of the abnormal rhythm and can permanently cure your child's problem.
- To ensure your child is comfortable during the procedure, we perform most studies under anesthesia delivered by an experienced pediatric anesthesia team. We have performed these procedures in children of all ages, including young infants.
Our electrophysiologists also have expertise in the diagnosis and treatment of children with slow heart rhythms and different types of heart block that may require the implantation of a pacemaker.
- When the heart rhythm is too slow, a pacemaker can stimulate the heart, preventing symptoms.
- For children with certain conditions that can lead to a life-threatening fast arrhythmia, we may use a permanent implantable cardiac defibrillator (ICD). An ICD can potentially save a child's life by sensing and treating a life-threatening arrhythmia.
Our approach to care
Multidisciplinary and collaborative care
Arrhythmias are sometimes caused by other heart issues, such as congenital heart defects or cardiomyopathy. Our team of pediatric cardiac experts, including pediatric electrophysiologists, cardiologists, pediatric cardiac surgeons, pediatric anesthesiologists, and pediatric cardiac nurses, closely collaborate to find the root cause of the arrhythmia and provide your child with the safest, most advanced treatment available.
Our pediatric electrophysiologists employ the most advanced tools and state-of-the-art technologies to assess and treat arrhythmias, including:
- Wireless heart rhythm monitoring
- Implantable cardiac devices
- Management of children with pacemakers and implantable defibrillators (ICD)
- Ablation of cardiac arrhythmias
- 3D imaging in ablation procedures
- Assessment of arrhythmias related to genetic abnormalities
- Assessment of family members of victims of sudden death
Accurate diagnosis and effective treatment
The most important step in your child's care is an accurate and timely diagnosis. We offer diagnostic testing to determine the type and location of the abnormal heart rhythm. Armed with that knowledge, we tailor a customized treatment plan for your child using medication, ablation, or the implantation of a pacemaker or other device to restore a normal rhythm to your child's heart.
Specialized fetal care
At NewYork-Presbyterian, our electrophysiologists participate in the care of fetal arrhythmias by treating the mother with anti-arrhythmic medications and working with our maternal-fetal medicine specialists to treat the arrhythmia before birth.
Why choose us
Extraordinary experience in pediatric electrophysiology
Our pediatric electrophysiology team is specifically trained in performing electrophysiology procedures in children, which requires an in-depth knowledge of anatomical development and the use of smaller catheters. We routinely provide second opinions and treat patients with complex conditions who have not found successful treatment elsewhere.
Less Invasive and Safer Approaches to Care
NewYork-Presbyterian is at forefront of developments in technologies that have made arrhythmia treatment less invasive, with lower radiation exposure. Today, our pediatric electrophysiologists perform most arrhythmia ablation procedures with 3D mapping technology, which eliminates the need for fluoroscopy imaging and the radiation exposure it involves.
Translational Research in Pediatric Cardiac Care
NewYork-Presbyterian’s pediatric heart specialists are international leaders in pediatric cardiac research initiatives and discoveries to advance the care and improve the lives of our young patients with heart disease. Our teams participate in trials of arrhythmia therapies and implantable devices, as well as quality outcomes and safety metrics registries.
