Your Child's Heart Rhythm Monitoring

The rate or pattern of the heartbeat is known as the heart rhythm. Abnormal heart rhythms are called arrhythmias. These can cause your child to have symptoms such as lightheadedness, dizziness, low blood pressure, fainting, or fatigue. Rarely, arrhythmias can cause more serious problems. To help the doctor learn more about your child's heart rhythm, tests can be done.
