Resuscitation electrodes are placed according to one of two schemes. The anterior-posterior scheme is the preferred scheme for long-term electrode placement. One electrode is placed over the left precordium (the lower part of the chest, in front of the heart). The other electrode is placed on the back, behind the heart in the region between the ...
The working electrode is one of the electrodes at which the oxidation/reduction reactions occur—the processes that occur at this electrode are the ones being monitored. The auxiliary electrode (or counter electrode) is the one at which a process opposite from the one taking place at the working electrode occurs.
He will guide the (steerable) electrodes to the correct position inside the heart. The electrophysiologist begins by moving the electrodes along the conduction pathways and along the inner walls of the heart, measuring the electrical activity along the way. Doctors conduct an electrophysiology study in the hospital's cardiac catheterization ...
A potentiostat is a control and measuring device. It comprises an electric circuit which controls the potential across the cell by sensing changes in its resistance, varying accordingly the current supplied to the system: a higher resistance will result in a decreased current, while a lower resistance will result in an increased current, in order to keep the voltage constant as described by ...
An EEG recording setup using the 10-10 system of electrode placement. EEG is the gold standard diagnostic procedure to confirm epilepsy.The sensitivity of a routine EEG to detect interictal epileptiform discharges at epilepsy centers has been reported to be in the range of 29–55%. [8]
MELF: Metal electrode leadless face (usually for resistors and diodes) SOD: Small-outline diode. SOT: Small-outline transistor (also SOT-23, SOT-223, SOT-323). TO-XX: wide range of small pin count packages often used for discrete parts like transistors or diodes. TO-3: Panel-mount with leads; TO-5: Metal can package with radial leads
The placement of electrodes, as well as the dose and duration of the stimulation is determined on a per-patient basis. [1]: 1881 In unilateral ECT, both electrodes are placed on the same side of the patient's head. Unilateral ECT may be used first to minimize side effects such as memory loss.
Allowing the placement of multiple electrodes at once rather than individually; The ability to set up controls within the same experimental setup (by using one electrode as a control and others as experimental). This is of particular interest in stimulation experiments. The ability to select different recordings sites within the array
