ELECTRONICS PLAYS IN MEDICAL FIELDS

• ECG • EEG • EMG • PCG • EOG • ANIMAL CELLS
ECG
Deals with the study of electrical activity of the heart muscles. The potentials originated in the human being fibres of heart muscles are added to produce the ECG waveform. Electrocardiogram is the recorded ECG wave pattern. Heart consists of four chambers namely two auricles and two ventricles. Cardiac action potential is generated by contraction and expansion of the muscle fibres.

HOW DOES IT PLAY
EEG
Deals with the recording and study of electrical activity of brain. By means of electrodes attached to the skull of the patients , the brain waves are picked up and recorded.
Electromyography (EMG)
It is the science of recording and interpreting the electrical activity of muscle’s action potential. Recording of peripheral nerve’s action potential is called ELECTRONEUROGRAPHY
Electrooculography (EOG)
It is a technique for measuring the resting potential of the retina.
the resulting signal is called the electrooculogram. The main applications are in ophthalmological diagnosis and in recording eye movements.

WHAT IS ENDOSCOPY?
An endoscope is a medical device consisting of a camera mounted on a flexible tube. Small instruments can be used to take samples of suspicious tissues through the endoscope. In gastrointestinal (digestive tract) endoscopy, this device is inserted through the mouth or anus. For other areas, small incisions are made.
WHAT IS LASER?
Laser is an acronym for Light Amplification by Stimulated Emission of Radiation. Laser beam consists of high intense radiation in unique direction without spreading of its energy in other directions.
