Rhabdomyolysis

On the morning of Sept. 8, 18-year-old Paul Houle Jr. lined up in his nose tackle position at the year's first football practice, feeling healthy and ready to take on the season ahead.

By 8 p.m., Houle was in an emergency room at a nearby hospital. His heart, liver and kidneys were all shutting down.

"Doctors told me that if I had not said anything and gone to practice the next day, I very easily could have died," Houle told The Huffington Post over the phone.

Houle, a senior at Tabor Academy in Marion, Massachusetts, had come down with an acute condition called rhabdomyolysis after participating in two football practices in the sweltering heat, Cape Cod-based health care news service One Cape Health News first reported. The condition is a known risk for amateur athletes engaging in physically strenuous summer workouts.

Houle was dehydrated and overheated from participating in two practices in one day, and the muscles in his body had begun to break down and release a protein into his bloodstream that was causing his vital organs to fail.

Houle told HuffPost that after the day's second practice, he felt back pain whenever he took a deep breath.

"I thought I was just sore and a little out of shape because the practice was hard. I didn’t think much of it," he said. "Later, when I was at the hospital, they let me know that my back pain was actually my kidneys failing."

Back at his dorm room after practice, Houle said he showered and took a short nap. When he woke up, he checked his Apple Watch's heart rate monitor for the first time that day. He knew something was wrong immediately. The watch indicated his heart rate was 145 beats per minute, a full 60 to 80 beats higher than an average resting heart rate. He didn't know it then, but a rapid heart rate is a symptom of rhabdomyolysis.

In fact, he actually thought the watch was broken. He had never considered its heart rate monitor to be anything more than a gimmick.

"I thought it was a neat little feature, but didn’t see myself really using it," he said. "What I thought was so tiny and not important turned out to be a life-changing decision."

The school's athletic trainer also thought the watch was broken when Houle told him about his abnormally high heart rate reading. But after being examined by both the trainer and the school's nurse, he was immediately driven to the emergency room. Once at the hospital, Houle was diagnosed with rhabdomyolysis and began receiving treatment, but the condition's effects still caused him to lose control of his muscles...

As a senior proctor at his boarding school, Houle lives alone in a single room. He would have had difficulty finding help late at night once the rhabdomyolysis had rendered him immobile. He credits the Apple Watch for quickly compelling him to seek the help he needed to prevent his body from fully shutting down.
