声音简介
Both the heart muscle and the nervous system produce electrical impulses that can be measured with special machines. The electrocardiograph (ECG) is useful for diagnosing certain heart conditions. With electrodes taped to a person’s chest, the electrical activity of the heart can be recorded while the patient is either resting or performing some activity, such as walking on a treadmill. The electroencephalogram (EEG) measures the electrical activity of the brain through electrodes attached to the head. This test detects whether there is an area of irritability in the brain, such as occurs in epilepsy. The electromyogram (EMG) records the activity of nerves in muscles. The EMG is helpful in diagnosing degenerative nerve disorders such as multiple sclerosis.
Tests of pulmonary function measure the breathing capacity of the lung and airways. By exhaling into a tube connected to a machine called a spirometer, information is obtained on respiratory functions.
