Indifferent electrode. in unipolar electrocardiography, a remote electrode placed either upon a single limb or connected with the central terminal and paired with an exploring electrode; the indifferent electrode is supposed to contribute little or nothing to the resulting record.
What is active and indifferent electrode?
From the functional point of view, ECG electrodes are divided into 2 types – active (or exploring) and indifferent (reference or zero) electrodes. The active electrode measures the variable potential of the cardiac electric field. In ECG examination, two types of lead are used – bipolar and unipolar.
What does ground electrode means?
[′grau̇nd i¦lek‚trōd] (electricity) A conductor buried in the ground, used to maintain conductors connected to it at ground potential and dissipate current conducted to it into the earth, or to provide a return path for electric current in a direct-current power transmission system.
What is exploring electrode?
an electrode placed on or near an excitable tissue; in unipolar electrocardiography, the electrode is placed on the chest in the region of the heart and paired with an indifferent electrode.
What do you mean by indifferent?
1a : marked by a lack of interest, enthusiasm, or concern for something : apathetic indifferent to suffering and poverty. b : marked by no special liking for or dislike of something indifferent about which task he was given.
What are augmented limb leads?
Augmented limb leads. The potential difference between the reference electrode and an exploring electrode constitutes the augmented lead. The three exploring electrodes are the right arm (R), the left arm (L), and the left leg (F).
What is active electrode in electrotherapy?
active electrode therapeutic electrode. point electrode an electrode having on one end a metallic point; used in applying current. therapeutic electrode one smaller than an indifferent electrode, producing electrical stimulation in a concentrated area; called also active electrode.
What is stimulator in physiotherapy?
Electrical muscle stimulation (EMS) is a type of electrotherapy stimulates a muscle contraction using electrical impulses in order strengthen weak muscles, reduce swelling, relieve pain and help heal wounds.
Why do you need a ground electrode EMG?
The primary purpose of the ground is to prevent power line noise from interfering with the small biopotential signals of interest. A ground electrode for EEG recordings is often placed on the forehead (but could be placed anywhere else on the body; the location of the ground on the subject is generally irrelevant).
What is reference electrode in EMG?
Reference electrode placement. The signal from the EMG detecting surfaces is gathered with respect to a reference. An EMG reference electrode acts as a ground for this signal. It should be placed far from the EMG detecting surfaces, on an electrically neutral tissue [15].
What is the meaning of electrode indifferent?
Here are all the possible meanings and translations of the word electrode, indifferent. A term in electro-therapeutics. An electrode to which no therapeutic action is attributed but which merely provides a second contact with the body to complete the circuit through the same.
What is the indifferent electrode on an ECG?
What do you mean by an indifferent electrode in ECG? The electrode connected to the right leg is usually taken as the indifferent electrode in ECG (electrocardiogram). Other electrodes form either the positive or negative pole of each lead, while the indifferent electrode forms the reference electrode and may be connected to the equipment ground.
What are the causes of indifference?
There can be group and bystander effects causing indifference. When we see others being indifferent and apathetic, then we may be tempted to go along with the crowd. But the opposite may also be true.
What is an anterioran electrode?
an electrode that has a resistance greater than that of the portion of the body enclosed in the circuit.
