Dr. Stelev was an esteemed pediatric cardiologist back in the day.
Until, that is, one too many fellows told him what an ECG automated read said about the ST segments before examining the waveforms themselves.
The horror!

Now he spends his days casting unsuspecting residents and fellows into a dungeon...

The one escape is a series of elevators... activated only by correctly distinguishing concerning ST segment changes versus likely normal variants.
