Jason's Blog: ECG Challenge of the Week for Sept. 16-23. What probable clinical disorder is this tracing suggestive of?

Unfortunately this 12-lead ECG is over 20-years-old, so I have very limited information to go on but this is what I do know about it.

Patient's clinical data:  81-year-old black man with history of Alzheimer's disease (dementia).  The patient's son transported his father via POV to the emergency department's triage room.  Patient had essentially been "failing to thrive" and his presenting blood pressure was hypotensive at 80/62.  Subsequently he was admited to the ICU, intubated, and placed on a ventilator.  He ended up dying about 2 weeks later.

The computer's interpretation was:
Marked sinus bradycardia
Nonspecific intraventricular block

What probable clinical disorder is this tracing "suggestive of"?

 Marked sinus bradycardia with diffuse J wave elevation, long QT and non-specific T wave abnormality should raise the suspicion of hypothermia and hypothyroidism. Some neurological disorders associated with marked J wave elevation as well hypercalcemia, but the later is associated with short QT.
