What is the most effective way to correct ECG artifact?

The most effective method for correcting ECG artifact is by re-referencing and repositioning wires. This is crucial because many ECG artifacts originate from poor electrode placement or lead disconnection, leading to incorrect signals. By ensuring that the wires are properly attached and positioned, you can significantly reduce noise and interference, resulting in clearer and more accurate readings.

When wires are repositioned, it helps to establish better contact with the skin and reduces movement artifacts caused by patient motion. Additionally, re-referencing can help isolate the true cardiac signals from various types of interference that may be present in the recording.

Other approaches, such as adjusting the patient's position or applying noise filters, can be helpful in specific scenarios, but they do not address the underlying issues related to the electrode setup as effectively as re-referencing and repositioning do. Increasing amplification may enhance the signal but can also amplify the noise, leading to distorted results instead of resolving the artifacts.
