Key Takeaways
- An ECG artifact is interference or noise that appears on an ECG recording, which is not generated by the heart's rhythm. It can be caused by factors like movement, poor electrode contact, electrical interference, or muscle tremors, leading to an erratic and irregular pattern on the ECG that does not correspond to the heart's electrical activity.
- ECG artifacts, in themselves, do not directly impact heart health as they are not indicative of a heart problem. However, they can lead to misinterpretation of the ECG, potentially causing unnecessary worry, further testing, or inappropriate treatment. Misinterpretation may occur when artifacts are mistaken for actual heart rhythms, such as atrial fibrillation or ventricular tachycardia.
- Recognizing ECG artifacts is crucial to avoid unnecessary concerns and interventions. Understanding how artifacts may manifest as irregular, inconsistent rhythms that do not align with how the person is feeling can help differentiate them from genuine heart rhythms. While watch ECGs can provide useful insights, they should not replace a full clinical ECG or professional medical advice. If unsure about an ECG reading, consulting a healthcare professional is recommended.

Introduction
Electrocardiograms (ECGs) have always been an important tool in monitoring heart health. With the advent of smartwatches and other wearables that can record an ECG, understanding the heart's rhythm and identifying abnormalities has become significantly more convenient. An intriguing feature that can often appear on these ECGs is not a heart rhythm, but an artifact. Artifacts can lead to misinterpretation and unnecessary concern, making it important to know how to recognize them. This article will help you understand what an ECG artifact is and how it can impact your heart health. Let’s dive in.
What’s an ECG Artifact?
An ECG artifact is essentially noise or interference that can appear on an ECG recording. It's not a rhythm generated by the heart, but a disruption in the recording caused by various factors like movement, poor electrode contact, electrical interference, or even muscle tremors. This interference results in an erratic and irregular pattern on the ECG that doesn't correspond to the heart's electrical activity. On an ECG reading, artifacts can manifest in several ways. They may appear as rapid, irregular spikes that seem completely out of sync with the underlying rhythm. They can also present as a baseline sway or wiggle, which can be mistaken for actual heart rhythms. In extreme cases, artifacts can overshadow the actual heart rhythm, making it difficult to interpret your ECG.

How Do ECG Artifacts Impact My Heart Health?
It's important to understand that an ECG artifact, in itself, doesn't directly impact your health, since it isn’t indicative of a heart problem. However, its presence can potentially lead to misinterpretation of your ECG, which might result in unnecessary worry, further testing, or even inappropriate treatment.
For example, you may have a normal sinus rhythm with artifact, which is complete normal. A "fluttering" artifact might be wrongly interpreted by watch as an Afib ECG. Or a regular high-frequency artifact could be mistaken for a V Tach ECG. Both of these scenarios could lead to unnecessary interventions and anxiety.
Therefore, understanding how to identify an artifact on an ECG is crucial. If your watch ECG frequently shows an irregular, inconsistent rhythm that doesn't correspond with how you're feeling, it may be an artifact. However, if you're ever in doubt about a reading, it's essential to consult a healthcare professional.
Remember that while watch ECGs can provide useful insights, they are not a replacement for a full clinical ECG or professional medical advice. By understanding what an artifact on an ECG looks like, you can ensure you're making the most of your watch ECG without falling into the trap of artifact misinterpretation.
