In this article we will discuss about the transmission of cardiac impulse of humans with the help of suitable diagram. 1. Conduction over Atrial Muscle: Cardiac impulse originated at the S.A node is transmitted over both the atria like concentric waves and thus the P wave is produced in E.C.G. (Electrocardiogram). The spread of electrical […]
