As told by John James
Nineteen-year-old Alex James, a Texas college student, collapsed while running on a university jogging path in the late August heat. He recovered and was taken by ambulance to the emergency room, where tests showed a low potassium level and an abnormal heart rhythm called a long QT interval.
Alex was seen by a cardiologist and by a consultant recommended a cardiac MRI. Alex thought one had been done since he was put through the procedure, but we later learned that the test had been aborted because the technicians at the hospital were not trained on new software. On the basis of this “inconclusive” MRI, Alex gave consent for a cardiac catheterization and an electrophysiology test, both invasive procedures. He spent four days in the hospital and a fifth day as an outpatient at a second hospital undergoing these procedures. He was never told that the cardiac MRI was not completed.
Alex’s heart catheterization and electrophysiology test showed no structural abnormalities. He did, however, meet the criteria for a diagnosis of long QT syndrome, a dangerous condition that can lead to sudden death. Inexplicably, this diagnosis was not made. One possible cause of long QT syndrome is low potassium, which can be brought on by strenuous exertion in a hot climate. The protocol in such cases is to replenish low potassium. Although we were told in the hospital that this would be done, it never was.
The doctor at the second hospital told Alex not to run and wrote this restriction in the medical record. However, the medical record also shows that Alex was given a second milligram of Versed, a drug known to cause loss of memory, just before being warned not to run. The total dose of Versed in Alex’s case was quite high for a 155-pound man. The only written instruction given to Alex when he was discharged a few hours later was not to drive for 24 hours. Alex was a good patient. He followed instructions and did not drive, but he apparently had no memory of the warning not to run.
Five days later Alex was seen by a family practice physician the cardiologists had recommended. This young doctor, still in her residency, lacked basic knowledge of cardiology. She did not know that Alex was supposed to be referred for genetic testing and gave him a clean bill of health.
Two and a half weeks later Alex was again running alone on the jogging trail. About a mile into his last run he collapsed and was found unresponsive by a passer-by. He died after three days in a coma. Pathology showed heart injury consistent with severe potassium depletion.
