Most drugs can be detected in hair for about 90 days. This does depend on how long someoneâs hair is, how frequently they have haircuts, and how much of a drug theyâve taken. Additionally, trace amounts of morphine will be harder to detect.
How is an EKG (electrocardiogram) performed? Your EKG will be performed in a hospital, clinic, doctorâs office, or sometimes in the home or an ambulance. A standard or resting EKG, the most common type of EKG, takes a few minutes. It generally includes these steps: You will recline in a comfortable position. Your provider will attach sticky patches, or electrodes, to your chest and possibly your arms and legs or hips and shoulders. This is painless.
Sometimes EKG abnormalities can be seen only during exercise or while symptoms are present. This test is sometimes called a stress test or a treadmill test.. During an exercise EKG, you may either walk on a motor-driven treadmill or pedal a stationary bicycle. The heart is a muscular pump made up of four chambers . The two upper chambers are called atria, and the two lower chambers are called ventricles.
