The pulse that is measured reflects the number of heart beats per minute, or in other words – the heart rate. (Heart beat is defined as one systole and one diastole.)
The normal pulse rate of an adult person is between 60 – 100 per minute and tends to increase in states of exertion or excitement and to decrease at rest or during sleep.
The pulse can be felt due to contraction and widening of an artery palpated following filling or emptying of blood through the action of the heart.
The pulse can be felt in the Radial artery (in the wrist), in the Femoral artery (in the inguinal region), in the Carotid artery (in the neck) as well as in other locations of the body.
