My pediatric cardiologist was extremely concerned about me by the time I was thirteen. He stayed in close contact with Dr. Kaye, my adolescent medicine doctor. When I was lying down on that crinkly white paper on the exam table, my heart rate was usually about 120. Sitting up it was usually about 135, and when I stood up, it was in the 150s. Neither Dr. Kaye or Dr. Oster, the cardiologist, ever said anything about those numbers being abnormal, but I read it right off their faces.
After they left the room I looked it up on my phone. A normal heart rate for a teenager is 60 to 100 beats per minute, and it shouldn’t fluctuate like that with changes of position.
Dr. Oster said they wanted to run a bunch of tests on my heart shortly before my fourteenth birthday. I was not surprised.
