An EEG is a device which records the electrical activity from different parts of the brain and converts it into a tracing called an electroencephalogram or EEG. The machine that records this activity is known as an encephalograph. The pattern of the EEG reflects the state of the patient's brain and the level of consciousness in a characteristic manner. A recording of the electrical impulses of the brain can be used to diagnose certain diseases (such as epilepsy), furnish information regarding sleep and wakefulness and confirm brain death.



Nerve conduction studies (NCS) and electromyography (EMG) are specific tests that help physicians determine how nerves and muscles are working. NCS measures how electrical signals travel through the nerves, and EMG records the signals moving through the muscles. Together, these tests are often called “EMG testing.”

The nerves tested in nerve conduction studies are called “peripheral nerves.” They are the nerves outside of the brain and spinal cord carrying messages throughout the body. They allow patients to receive sensory information and control muscles. EMG testing can help physicians diagnose many different neuromuscular and muscular disorders.



An electrocardiogram (EKG or ECG) is a test that checks for problems with the electrical activity of your heart. An EKG translates the heart's electrical activity into line tracings on paper. The spikes and dips in the line tracings are called waves.



Cardiac stress testing can be useful in identifying partial blockages in your coronary arteries. The stress test is used to evaluate the heart and vascular system during exercise. Many times, the presence of coronary artery disease (CAD) is easily missed when a person is at rest because at rest there may be no sign of a problem either on physical examination or on the ECG. In these cases, cardiac abnormalities may become apparent only when the heart is asked to perform at increased workloads.



Pulmonary function tests are a group of tests that measure how well the lungs take in and release air and how well they move gases such as oxygen from the atmosphere into the body's circulation. During a spirometry test, you breathe into a mouthpiece that is connected to an instrument called a spirometer. The spirometer records the amount and the rate of air that you breathe in and out over a period of time.



Our sleep disorders physicians diagnose and treat patients with complaints related to sleeping and waking functions. Patients usually spend the night in the center and leave in time for work the next morning. Rooms are attractively furnished and have private baths. Breakfast is served in the cafeteria for patients who prefer to dine before leaving the hospital. Testing involves non-invasive electrodes that are attached to the scalp and skin. These monitor sleep stages, heart rate, respiration, leg and eye movements and blood oxygen levels.
