Electrocardiography, Ambulatory
|
D015716 |
[Method in which prolonged electrocardiographic recordings are made on a portable tape recorder (Holter-type system) or solid-state device ("real-time" system), while the patient undergoes normal daily activities. It is useful in the diagnosis and management of intermittent cardiac arrhythmias and transient myocardial ischemia.

|
Electrochemistry
|
D004563 |
[The study of chemical changes resulting from electrical action and electrical activity resulting from chemical changes.

|
Electrochemotherapy
|
D053672 |
[A cancer treatment modality that uses pulsed electrical currents to permeabilize cell membranes (ELECTROPORATION) and thereby enhance the uptake of chemotherapeutic agents into the body's cells.
] |
|
Electrocoagulation
|
D004564 |
[Procedures using an electrically heated wire or scalpel to treat hemorrhage (e.g., bleeding ulcers) and to ablate tumors, mucosal lesions, and refractory arrhythmias. It is different from ELECTROSURGERY which is used more for cutting tissue than destroying and in which the patient is part of the electric circuit.

Electroconvulsive Therapy
|
D004565 |
[Electrically induced CONVULSIONS primarily used in the treatment of severe AFFECTIVE DISORDERS and SCHIZOPHRENIA.

Electrocorticography
|
D000069280 |
[Recording of brain electrical activities in which the electrodes are placed directly on the CEREBRAL CORTEX.

|
Electrodes
|
D004566 |
[Electric conductors through which electric currents enter or leave a medium, whether it be an electrolytic solution, solid, molten mass, gas, or vacuum.

|
Electrodes, Implanted
|
D004567 |
[Surgically placed electric conductors through which ELECTRIC STIMULATION is delivered to or electrical activity is recorded from a specific point inside the body.
] |
|
Electrodiagnosis
|
D004568 |
[Diagnosis of disease states by recording the spontaneous electrical activity of tissues or organs or by the response to stimulation of electrically excitable tissue.
] |
|
Electroencephalography
|
D004569 |
[Recording of electric currents developed in the brain by means of electrodes applied to the scalp, to the surface of the brain, or placed within the substance of the brain.
] |
|
Electroencephalography Phase Synchronization
|
D058407 |
[Adjustment of BRAIN WAVES from two or more neuronal groups within or across a brain structure (e.g., cortical and limbic brain structures) to become uniform in EEG oscillation patterns in response to a stimulus. It is interpreted as a brain integration sign during many processes such as learning, memory, and perception and involves reciprocal neural connections.

|
Electrogalvanism, Intraoral
|
D004570 |
[Chemical reaction that occurs when saliva comes into contact with the metals in dental fillings. This reaction can send electric currents through the brain causing negative symptoms.
] |
|
Electrokymography
|
D004571 |
[Radiographic technique combining a photoelectric recording system with fluoroscopy. It is used especially with electrocardiography to study heart motion.
] |
|
Electrolysis
|
D004572 |
[Destruction by passage of a galvanic electric current, as in disintegration of a chemical compound in solution.
] |
|
Electrolytes
|
D004573 |
[Substances that dissociate into two or more ions, to some extent, in water. Solutions of electrolytes thus conduct an electric current and can be decomposed by it (ELECTROLYSIS). (Grant & Hackh's Chemical Dictionary, 5th ed)

Electromagnetic Fields
|
D004574 |
[Fields representing the joint interplay of electric and magnetic forces.

Electromagnetic Phenomena
|
D055590 |
[Charged particles, the properties and behavior of charged particles and other concepts related to or associated with ELECTRICITY.
, Characteristics of ELECTRICITY and magnetism such as charged particles and the properties and behavior of charged particles, and other phenomena related to or associated with electromagnetism.
, Phenomena involving magnets, electric currents through conductors and the electric and magnetic fields thus produced, as in electric motors.

Electromagnetic Radiation
|
D060733 |
[Waves of oscillating electric and MAGNETIC FIELDS which move at right angles to each other and outward from the source.
] |
|
Electromyography
|
D004576 |
[Recording of the changes in electric potential of muscle by means of surface or needle electrodes.
