Not a doc but I do exercise with a HRM. Something is not right. The exercise you describe is strenuous but not balls out 100% exertion. Max. heart rate should only occur at a strain level that you can't sustain more than a few minutes. That's too high a reading - either the monitor is inaccurate or your heart is going too fast. I would not experiment further and quit heavy exercise until you had a chance to see the heart doc and get a stress test.

Without going back to this exercise level, any idea what the recovery rate was from these episodes (how fast did HR come down after you stopped for a rest)?

Good Luck,
