You can calculate your heart rate in two ways. First, you could simply count the number of pulses for a given time period and adjust that to the number of pulses per minute. Or, you could measure the cycle time of the cardiac cycle. If you measure the cycle time to be 0.800 sec, what is the heart rate?

80 bpm

75 bpm

48 bpm

none of these

Solution

HEART BEAT = TIME / HEART RATE

Here time = 1 minute ie 60 sec.

so 60 / 0.80 = 75 beats/min

Hence option B
