what measuring instrument does we need to count our heart rates ?

OpenStudy (koikkara):

Welcome new user. Hmm..Heart rate is measured by finding the pulse of the heart. www.webmd.com/heart-disease/pulse-measurement

OpenStudy (anonymous):

well we use a stethoscope to find blood pressure...but if you want to count heart rate or heart beat you just place your finger on a artery usually on your wrist or under your jaw, and count.

OpenStudy (aaronq):

stethoscopes are to listen inside of bodies like an amplifier.. wait for it... sphygmomanometer is that band you put around your arm to measure blood pressure
