#TELEMETRY ARTIFACT MEANING SKIN#

This type of artifact is associated with transcutaneous pacing (TCP). Some devices can be temporarily turned off with a magnet but you should consult with the prescribing physician. If you see artifact that looks like this you should ask your patient if he or she has any implantable medical devices. These devices are used to treat a variety of symptoms including tremors, seizures, chronic pain, nausea and vomiting related to gastroparesis, problems with bladder or bowel control, visual impairment, and hypertension. Here’s a type of artifact we’re starting to see more frequently as implantable neurostimulators become more prevalent. However, if you’re performing CPR at a 30:2 compression to ventilation ratio you can see the underlying rhythm during ventilations! There may be times when CPR artifact makes it difficult to determine the underlying rhythm. Using the small block method (1500/13=115) we can determine that the compression rate was about 115/min. The wavy line after the shock is CPR artifact. This ECG was automatically recorded during a cardiac arrest. My department has been doing this for so long that I don’t have any good examples of 60 cycle interference! As long as the low frequency / high pass filter (the lower number) is set to 0.05 Hz you should get accurate ST-segments. To help minimize 60 cycle interference you can set the diagnostic mode of your 12-lead ECG monitor to 0.05 – 40 Hz. In the United States this is sometimes referred to as 60 cycle interference (or 60 Hz pickup). It made quite a difference didn’t it?Įlectromagnetic interference (EMI) artifact usually results from electrical power lines, electrical equipment, and mobile telephones. The next example was taken after a large towel was placed over the firefighter. It was cold in the fire station and he was shivering.

The example below was obtained from a young, healthy firefighter during routine training. However, it can also happen when patients prop themselves up by their arms. Usually it’s happening because your patient is cold and shivering. Muscle tremor (or tension) artifact is a type of motion artifact. There are times when your patient is acutely short of breath and it’s simply impossible to capture a 12-lead ECG with excellent data quality. I don’t do this because it can alter the patient’s heart rate. Some paramedics ask patients to hold their breath while they capture a 12-lead ECG. Some references suggest that wandering baseline can be caused by loose or dry electrodes. I have also noticed that stopping or accelerating the ambulance can cause wandering baseline. It can be caused by patient movement, including breathing.

Wandering baseline artifact presents as a slow, undulating baseline on the electrocardiogram. Lead I and lead II share the right arm electrode! That is the electrode that is causing this problem. Lead II is a dipole with the negative lead on the right arm and the positive electrode on the left leg.Lead I is a dipole with the negative electrode on the right arm and the positive electrode on the left arm.What electrode do leads I and II have in common? In this example loose lead artifact can be seen in leads I and II. However, tincture of benzoin is flammable! You don’t want to use it for defibrillation pads.

To troubleshoot this problem make sure you prep the skin carefully!Ĭonsider tincture of benzoin. You may also see this type of artifact when placing the electrode over hair. You will frequently encounter loose lead artifact when dealing with patients who are diaphoretic because the electrodes simply will not stick to the patient’s body. Here are some types of artifact you may encounter along with some tips to help you achieve excellent data quality on your ECG tracings. With a trained eye you can often learn to spot the underlying rhythm “marching” through this type of artifact. When we rushed to the patient’s room it turned out she was brushing her teeth! Once when I was a cardiac monitoring technician the alarm sounded and it appeared as though ventricular tachycardia was on the monitor. However, there are occasions when artifact mimics ECG abnormalities that can cause problems for patient care. Most of the time it will be obvious that you are dealing with artifact and troubleshooting the problem will be straight forward. Artifact on the electrocardiogram can result from a variety of internal and external causes from Parkinsonian muscle tremors to dry electrode gel.
