What does sinus rhythm artifact mean?

Sinus rhythm artifact indicates that the sinus rhythm shown on the electrocardiogram (ECG) is not truly abnormal, but rather reflects an error or interference.

In clinical practice, during ECG examinations, instruments may sometimes display artifacts labeled as "sinus rhythm artifact." This situation mostly arises due to interference from the equipment itself, primarily caused by static electricity. Such interference can lead to inaccuracies in the recorded sinus rhythm, potentially being mistaken for abnormalities caused by heart diseases. When a sinus rhythm artifact is present, the ECG is generally still considered normal. However, if patients remain concerned, further evaluation under a physician's guidance is recommended to confirm the diagnosis and implement appropriate treatment if necessary.

In daily life, if symptoms such as increased heart rate or irregular heartbeat occur, individuals should seek evaluation at a reputable medical facility. Prior to testing, it is advisable to avoid alcohol and tea, refrain from strenuous exercise, and minimize mental stress, so as not to affect test results or lead to misdiagnosis.
