i was doing research and i read that a recovery heart rate of 35bpm or more indicates almost no risk of sudden death by heart failure. I have done my recovery heart rate in forever, but i got it up to 150 after a min it was 130 after the second min 120... It took 5 min to get back down to 90bpm. Granted i was runnin on a speed stack, but should i be worried it took so long to go down?
