Question

Differentiate between ECG and EEG.

Answer 1

Hint: Bioelectric signals are very low amplitude and low frequency electrical signals that can be measured from biological beings, such as humans. Bioelectric signals are generated from a complex self-regulatory system and can be measured by changes in electrical potential across a cell or organ.

Complete answer:

EEG	ECG
Electroencephalogram or EEG is related to the brain	electrocardiogram or ECG is related to the heart
It is for measuring the electrical activities of brain	It is to measure the activities of heart
EEG is primarily used to diagnose seizure disorders, infections, tumors, degenerative disorders and metabolic disorders that may affect the brain.	ECG is used to determine the heartbeat rate, the position of the heart chamber, and if there is any damage to the heart. The ECG helps to determine if a person has any heart problems.
The German psychiatrist Hans Berger has been credited with inventing the EEG.	Augustus Waller of St Mary's Hospital in London was the first person to approach the heart systematically from an electrical point of view. He used the capillary electrometer of Lippmann to determine the electrical impulses of the heart. However, a breakthrough in ECG testing came with a string galvanometer developed by Willem Einthoven of the Netherlands.
In EEG, electrodes are attached to the scalp	The electrodes are attached to the chest, legs, arms and neck in ECG.
EEG comes with certain adverse conditions.	ECG involves no risks or pain

Note: Neither the EEG nor the ECG is harmful to your health. These tests measure electrical activity in your body to help make a diagnosis, but they do not send electrical activity to your body.
