Electrocardiography is the process of recording the electrical activity of the heart over a period of time using electrodes placed on the skin. It is abbreviated as (ECG or EKG). A normal ECG is shown below. Fig. 1 Electrocardiograph An electrocardiograph is a machine that is used to perform electrocardiography. Electrocardiogram It is the heart’s … Read more

The human body consists of 10 System viz. Skeletal System, Muscular System, Nervous System, Endocrine System, Respiratory System, Cardiovascular system, Lymphovascular system, Digestive System, Excretory System and Reproductive System.       Different organs can work together to perform a common function and works as an integrated unit called organ system or body system.  Body Systems … Read more

 In the previous article, we discussed Bioelectric potential, action and resting potential. In this article, we will talk about heart Cardiac Conduction System. A heart has its own electrical system that is responsible for the continuous generation and A heart has its own electrical system that is responsible for the continuous generation and organised transmission of … Read more

Bioelectric potentials   The ionic voltages produced as a result of the electrochemical activity of certain special types of cells are called as Bioelectric potentials. Resting & Action Potentials Our body is made up of different kinds of cells. The cell is the smallest unit of a living thing. The cell is surrounded by a … Read more
