4. •Heart rate monitors are devices that
detect and measure your heart or pulse
rate, i.e. (the speed of Heartbeat).
•A person's Heartbeat is the sound of
valves in his heart expanding or
contracting as they force blood from one
region to another
•There are two ways to monitor the heart
rate:
a. one way is to manually check the pulse
either at the wrists or neck
b. the other way is to use a Heartbeat
Sensor.
