Not only can the EKG be used to analyze the electrical conduction in the heart, but it can also be used to measure the heart rate. If the time interval between the peaks of two consecutive QRS complexes is 750msec, what is the heart rate of that person in beats per minute (BPM)?
a. 60
b. 65
c. 70
d. 75
e. 80

Simple calculation
750 m sec = 1cycle
1msec = 1/750 cycle
1 sec = 1x1000/750 cycles
60 sec = 1x1000x60 /750 cycles = 60,000/750 =80 cycles /min
Best of luck
