Heart Rhythm Disorders

Arrhythmia occurs when your child’s heart beats too fast, too slowly, or irregularly. Some arrhythmias are temporary and don’t pose any risks to your child’s health, while others are more serious.

Experience Matters

At Wolfson Children’s Hospital, our expert pediatric electrophysiologists offer diagnosis, advanced treatment and monitoring of heart rhythm disorders (arrhythmias). Using the latest medicines and therapies, we strive to keep your child’s heart in rhythm so they can live a healthy life at their own pace.
