Two-thousand times a day, Austin Miller’s heart rate would race – sometimes in excess of 200 beats per minute, nearly twice the rate of a normal child’s heart. His abnormal heart rhythm, a rare arrhythmia in children known as Junctional Ectopic Tachycardia (JET), took a toll on Austin’s young life. It caused him to feel irritable and affected his performance at school. When he was first diagnosed at age 3, doctors also told Austin’s parents that his rapid heart rhythm would prevent him from playing sports and require him to take medication for the rest of his life.
