Using EEGs to Identify Sleep Disorders
EEGs, or electroencephalograms, have proven to be a valuable tool in identifying sleep disorders. By measuring the electrical impulses in the brain, these tests can provide valuable insights into the complex interplay of brain activity during sleep. The discovery of different sleep stages in the 1950s was made possible by analyzing brain waves and monitoring eye and limb movement using EEG technology.
EKGs: Uncovering Stress through Electrical Activity
An EKG stress test, also known as a treadmill test, is a diagnostic procedure that records the electrical activity of the heart. While stress tests were historically performed during routine check-ups for middle-aged and older individuals, particularly men, they now serve as a valuable tool in detecting heart disease and identifying blood flow irregularities. If a patient is suffering from chest pain or experiencing shortness of breath, a doctor may recommend this test. However, it is important to note that the patient must be physically capable of exercising to undergo this procedure.
