Polar HRMs would often max out when you rode anywhere near high voltage - trams tracks, big overhead powerlines, etc.
If it reads as if you're dead then it's usually the chest strap failing to read properly. Wipe some spit on the sensors and your chest. You can get special gel for this but I prefer the porno methods.
