Biotelemetry consists of two parts i.e. Bio and Telemetry. Bio is related to living being or process or phenomenon occurring in the human body. Telemetry is the measurement at a distance. So, Biotelemetry is a method of measuring biological parameters from
LASER Working | Types & Applications
LASER LASER stands for Light Amplification by Stimulated Emission of Radiation. LASER is a narrow beam of light of a single wavelength (monochromatic) in which each wave is in phase(coherent) with other near it. Laser apparatus Laser apparatus is a
X-ray Working | Applications
X-rays It is a form of electromagnetic radiation having a high frequency (energy) or shorter wavelength. It has no mass, no charge but has energy. It travels at the speed of light When an X-ray is projected on the human
Ultrasound Principle | Working & Applications
What is Ultrasound? Ultrasound or ultrasonography is a medical imaging technique that uses high-frequency sound waves and their echoes to create images of the inside of the body. This technique is similar to the SONAR used by submarines, echolocation used by bats, dolphins, and
Human Body Anatomical Planes & Sections
Body Planes They are the hypothetical geometric planes that are used to divide the body into sections. Body Planes are commonly used in both human and zoological anatomy to describe the location or direction of bodily structures. 1. Sagittal or
Electroencephalography or EEG
Electroencephalography or EEG is the technique of capturing brain’s electrical activity. It was first discovered by Hans Berger in 1929. EEG signal recording can be done using scalp electrodes or intracranial procedure of capturing EEG. International 10-20 system of electrode
Types of ECG
In previous, article we discussed ECG (Electrocardiogram). In this article, we will see about different types of ECG. The type of ECG monitoring depends on the frequency and severity of symptoms. There are three types of ECG monitoring i.e. resting ECG,
What is Holter Monitoring?
Holter Monitor It is a small, wearable device that records your heart rhythm. It is very similar to a mobile phone. A patient usually wears a Holter monitor for one to three days. The device will record all of your heart

Electrocardiography (ECG or EKG)
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
