 The history and discovery of arterial pulse was a combination of great works done by physicians from many different countries. Kanada, an Indian had a theory which stated that pulse has three stages which reflect diseases in either air, bile or phlegm. In ancient times, the Indians heart rate was counted per" pal" with every 2.5 pal making a minute and also pulse rates were described according to age. In ancient China, the principal diagnosis employed was the physical examination of arterial pulse.

He also discovered that the heart and arteries intrinsically pulsate and that arteries and veins carry the same blood. Many years after Galen his work continued to be used until, Harvey later revolutionized the cardiovascular system. He carried out experiments on humans and proposed that the heart pumps blood and it circulated in a ...
