Concept about Electroencephalogram
An EEG, or electroencephalogram, is a test that records the electrical signals of the brain.
Or
An electroencephalogram (EEG) is a test used to evaluate the electrical activity in the brain. Brain cells communicate with each other through electrical impulses. An EEG can be used to help detect potential problems associated with this activity.
Indications of Electroencephalogram (EEG)
EEG is used to confirm or rule out various conditions, including:
- Seizure disorders (such as epilepsy)
- Head injury
- Encephalitis (inflammation of the brain)
- Brain tumor
- Encephalopathy (disease that causes brain dysfunction)
- Memory problems
- Sleep disorders
- Stroke
- Dementia
Electromyogram
A test that records the electrical activity of muscles. Normal muscles produce a typical pattern of electrical current that is usually proportional to the level of muscle activity.
Or
Electromyography (EMG) is a diagnostic procedure that evaluates the health condition of muscles and the nerve cells that control them. These nerve cells are known as motor neurons.
Indications:
- Tingling
- Numbness
- Muscle weakness
- Muscle pain or cramping
- Paralysis
- Involuntary muscle twitching (or tics)
Defibrillator
Defibrillators are devices that restore a normal heartbeat by sending an electric pulse or shock to the heart. They are used to prevent or correct an arrhythmia, a heartbeat that is uneven or that is too slow or too fast. Defibrillators can also restore the heart’s beating if the heart suddenly stops.
or
Defibrillators are the devices used to deliver shocks to the heart in cases of life threatening cardiac disorders.
Indications
- Secondary prevention of sudden cardiac death (SCD) in patients with prior sustained
- Ventricular Tachycardia (VT),
- Ventricular Fibrillation (VF), or
- Resuscitated SCD thought to be due to VT/VF
