What doesn't make sense to me, is potassium imbalance (whether hypokalemia[low] or hyperkalemia[high]) is not without symptoms, and sometimes severe symptoms at that.
If she was being monitored by doctors for infertility it seems incomprehensible that some notation of potassium imbalance symptoms wouldn't be on her charts. Not knowing the details of the malpractice lawsuit, I don't know if there was and the doctors didn't do anything or what. It would also seem logical she would have complained to friends or family.
Potassium imbalance can result in cardiac arrest, but an imbalance that severe surely would have produced noticable symptoms beforehand (as was obviously alleged in the lawsuit).
Now, unless it was very early on in the fertility issue, one would think they would have done blood work for hormone levels etc. I've never been to an OB/Gyn checkup where they didn't do at least routine blood work.
Unfortunately, it's difficult to make an informed assessment without the intimate details of the malpractice case and other events surrounding Terri.

Potassium imbalance >>and sometimes severe symptoms, at that<<

Potassium imbalance CAN be slow and insidious and deadly. To have reached the stage of cardiac arrest, the potassium level would have to be extremely low and developed over a period of time. The heart is a muscle, and it would show the loss of potassium as much as OTHER muscles of the body.

Been there ~ done that with Chronice Fatigue Syndrome. By the time potassium is at a critical point, the ability to stand and walk and carry is significantly impaired. The ability to think and reason is way off. She would have presented symptoms long before the verge of cardiac arrest, in my opinion. I've read she had none of these.
