the HR on the monitor instantly spiked up and instantly 'recovered' back down-- if it had really hit 211 it would have come down in a curve like the other variations on your graph. it was a misreading, i promise-- i have stared at cardiac monitors in icu for last 18 years fulltime and 211 would not suddenly recover as the graph indicated ever. unless it 'recovered' from 211 to ZERO
