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.
Electrocardiograms show the a graphic representation of the heart's various contractions and relaxations. This can be done, by hooking up an ECG machine to person, and running a stress test. The person may be asked to walk on a treadmill or lift weights until the heart rate gets up to a certain goal. You maintain that heart rate for several minutes as a cardiologist watches your ECG.
