    • ABSRACT - [ Total Page(s): 1 ]This work is on design and  construction of a heart beat monitor. Heart rate is a very vital health  parameter that is directly related to the soundness of the human cardiovascular  system. This project describes a technique of measuring the heart rate through  a fingertip. While the heart is beating, it is actually pumping blood  throughout the body, and that makes the blood volume inside the finger artery  to change too. This fluctuation of blood can be detected through an optical  sensing mechanism placed around the fingertip. The signal can be amplified  further for the system to c ... Continue Reading

         

      CHAPTER ONE - [ Total Page(s): 1 ]1.1 BACKGROUNDHeart beat rate means the number of heartbeats per unit time, usually expressed as beats per minute (bpm). The human heart pounds to pump oxygen rich blood to the muscles and carry cell waste products away from  the tissues. Heartbeat rate can vary according to the demand of the muscles to absorb oxygen and excrete carbon dioxide changes such as during exercise or sleep. It also varies significantly between individuals based on age, fitness and genetics. This means that the heart must beat faster to deliver more oxygen rich blood. During exercise routines, the heartbeat rate giv ... Continue Reading
