What is a monopolar needle?

What is a monopolar needle?

Made of stainless steel, the monopolar needle electrode has a very finely sharpened point and is covered with Teflon or other insulating material over its entire length, except for a 0.5 mm exposure at the tip.

What is concentric needle electrode?

Concentric Needle Electrode are used in Neuro-diagnosis. These are disposable. They are Electromyography pickup electrodes supplied with EMG machine interface cables ensuring cross contamination free and painless signal pickup. The electrodes are available in 25/40/50 mm sizes to suit all muscle types.

What are the different types of needle electrodes?

There are two types of needle electrodes: a simple straight needle; and a straight, hollow needle that contains several retractable electrodes that extend when needed.

What is the difference between EEG and EMG?

Electroencephalogram (EEG) is a non-invasive brain imaging technique that uses scalp electrodes to measure the voltage fluctuations induced by the mass electrical activity of neurons (1). Electromyography (EMG) technique is usually used to record the electrical activity produced by skeletal muscles (2).

What is a floating electrode?

The concept of floating electrode is introduced for defining the common electrochemical behaviour of any non-connected, electronically conducting, body immersed in an electrolytic medium.

What are the different types of electrodes?

Types and Examples of Electrodes

• There are mainly two types of electrodes namely reactive and inert electrodes.
• An inert type does not participate in any reaction while reactive types participate actively in reactions.
• Some commonly used inert electrodes include platinum, gold, graphite(carbon), and rhodium.

What’s the difference between EKG and EEG?

They may sound similar, but one of these things is not like the other: both ECG and EKG refer to a test of the heart, while EEG is a test of the brain. Electrocardiogram (ECG or EKG) is a painless test that measures the electrical activity in the heart.

What is EOG in EEG?

Electroencephalogram (EEG) refers to the brain waves, whereas electrooculogram (EOG) represents the eyeblinking signals. Both the signals possess complexities and various artifacts when they are recorded. In order to use these signals in biometric and clinical applications, preprocessing needs to be done.

What is suction electrode?

Suction electrodes are used with muscle research systems to record the action potentials from the stretch receptors at the same time that the length and tension of the muscle are recorded.

Which electrode is normally ECG?

Two types of electrodes in common use are a flat paper-thin sticker and a self-adhesive circular pad. The former are typically used in a single ECG recording while the latter are for continuous recordings as they stick longer.

What is mV in pH meter?

The pH meter measures the voltage potential difference (mV) between the sensing electrode and the outside sample (reference electrode) and via an algorithm displays a pH value.

What does the K stand for in EKG?

EKGs and ECGs are the same thing and both stand for ‘electrocardiogram. ‘ The abbreviation EKG comes from the German “elektrokardiogramm.” The first time the term was used in the medical literature was in a 1900 article published by the Dutch physician and physiologist, Dr.

What is a AKG test?

An electrocardiogram (ECG) is one of the simplest and fastest tests used to evaluate the heart. Electrodes (small, plastic patches that stick to the skin) are placed at certain spots on the chest, arms, and legs. The electrodes are connected to an ECG machine by lead wires.

What is EMG and EOG?

In a nutshell, EMG is essentially electrical “noise” generated by facial muscle activity near the electrode. EOG is electrical noise generated by eye movement. Some might consider EMG and EOG the evil cousins of EEG.

What is the difference between ERG and EOG?

The EOG had advantages over the ERG in that electrodes did not touch the surface of the eye. The changes in the standing potential across the eyeball were recorded by skin electrodes during simple eye movements and after exposure to periods of light and dark.
