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.
A stress EKG is a type of EKG done during exercise. A resting EKG is always done before an exercise EKG test, and results of the resting EKG are compared to the results of the exercise EKG. A resting EKG may also show a heart problem that would make an exercise EKG unsafe. To learn more, see the topic Exercise Electrocardiogram.
