What type of ecg artifact is caused by muscle movement, such as shivering?
An ECG artifact indicates something that is not “heart-made.” An ECG tracing is affected by patient motion. Some rhythmic motions (such as shivering or tremors) can create the illusion of cardiac dysrhythmia.Artifacts are distorted signals caused by a secondary internal or external sources, such as muscle movement or interference from an electrical device. Artifacts are extremely common, and knowledge of them is necessary to prevent misinterpretation of a heart’s rhythm.Distortion poses significant challenges to healthcare providers, who employ various techniques and strategies to safely recognize these false signals. Accurately separating the ECG artifact from the true ECG signal can have a significant impact on patient outcomes and legal liabilities.

Artifact when taking a 12 lead ECG is a very common occurrence, especially in a busy GP practice. Poor signal quality can cause noise, or artifact, on the ECG machine, which in turn can lead to inaccurate analysis of the final test. Thousands of 12 lead ECGs are performed every day in primary care and ensuring the highest quality ECG tests are performed will reduce patients having to be recalled for the test to be performed again or being referred to hospital for further testing. The following are a range of tips and best practices on reducing ECG artifact when taking an ECG in your practice:

These muscle tremors are known to frequently cause ECG abnormalities that may mimic cardiac pathology, including ventricular tachycardia [3] and atrial flutter [4,5].
What causes muscle tremors in ECG?Chronic re-innervation of the motor neurons produces somatic muscles fasciculation that appears as tremors during ECG tracing.
What should be done if patient is shivering during ECG?Patient tremor - make sure that the patient is relaxed by reassuring him or her and check that he or she is not moving or twitching (check fingers and toes especially!). If the patient is cold, cover him or her with a blanket.
Which artifact creates jittery patterns on an EKG tracing?Muscle (Somatic) Tremor
Choppy interference throughout the tracing is often caused by patient movement, even shivering or chewing gum can cause artifact known as somatic tremor.
