I have read the autopsy report. And I'm pointing out what Terri's Discharge Summary said when she was released from the hospital, as well as the doctors who were sued said about neglecting to run blood tests on her and catching her very low potassium levels which likely resulted in her cardiac arrest.
Whether 15 years later a pathologist can tell whether someone had cardiac arrest, I don't know.
But I do think that it's quite interesting that her Discharge Summary and doctors who testified under oath at multiple trials are discounted, while every conspiracy theory to come down the pike but can't be proven, are taken at face value.
A pathologist can't tell if there had been a cardiac arrest - he can only go by the medical records for such an event. No scarring of the cardiac muscle, as would have occured in a heart attack.
