Test Statistics-BioInstrumentation
In this article, we will learn about different test parameters that are required after performing medical tests on patients to analyse statistical data. We may define terms for test results 1. True positive (TP): A true positive test result is one that detects the condition when the condition is present. TP…
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, stress ECG, and ambulatory ECG. Ambulatory ECG is divided into…
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 rhythms during that time. So, a Holter monitor test is usually…
Biotelemetry System
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 a distance. The transmission of data from the point of…
Nervous System and Its Parts & Functions
Anatomy of the Nervous System Fig. Basic structure of a Neuron A neuron is the smallest unit of the nervous system. The neuron has a single cell body. The cell body is known as Soma. The long tail like structure connected with the cell body is known as Axon. The…
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 electrocardiograph is a machine that is used to perform electrocardiography.…
CardioVascular (Heart) Circulation System
In the previous article, we talked about different body system and their major organs and respective functions. In this article, we will see the anatomy of the heart, working and functions or CardioVascular (Heart) Circulation System. Blood enters the heart on the right side through two main veins: the superior vena…
Body Systems and Major Organs
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. …
Cardiac Conduction System
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…
Bioelectric Potentials, Resting & Action Potentials
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…
