Theory

In medical science one disorder is distinguished from another with the help of diagnosis. The basis of diagnosis includes patient's symptoms and signs, medical history, a physical exam, and laboratory tests. The medical history seeks the chief complaint (primary reason for seeking medical attention), history of present illness, past medical problems, family medical problems, social history, and review of symptoms. A physical examination is an orderly evaluation of the body and its functions. This process includes the noninvasive techniques of inspection, palpation, auscultation, and percussion along with measurement of vital signs (temperature, pulse, respiratory rate, and blood pressure). Therefore, body temperature and pulse along with other vital signs play significant role to determine a person's health preliminarily.

The alternate expansion and recoil of elastic arteries after each systole of the left ventricle creates a traveling pressure wave that is called the pulse. The pulse is strongest in the arteries closest to the heart, becomes weaker in the arterioles, and disappears altogether in the capillaries. The pulse may be felt in any artery that lies near the surface of the body. Increased resting pulse rate above 100 beats/ minutes indicates tachycardia where as bradycardia is a resting slow heart or pulse rate less than 50 beats/min.
