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.
An EKG is done to: 1  Check the heart's electrical activity. 2  Find the cause of unexplained chest pain or pressure. 3  This could be caused by a heart attack, inflammation of the sac surrounding the heart (pericarditis), or angina. 4  Find the cause of symptoms of heart disease. A stress EKG is a type of EKG done during exercise. 2  A resting EKG is always done before an exercise EKG test. 3  Results of the resting EKG are compared to the results of the exercise EKG. 4  A resting EKG may also show a heart problem that would make an exercise EKG unsafe.
