Although not a technical problem, filter settings influence the interpretation of the ECG. | Although not a technical problem, filter settings influence the interpretation of the ECG.<cite>Garcia</cite> | ||
[[File:Filter_settings.png|thumb|Filter settings can influence the interpretation of ST elevation as these examples show. On the left side an ECG with normal settigns (0.01-40Hz), on the right side a rhythm strip from the same patient with a different high-pass filter setting (0.32-40Hz). Also, the P wave morphology is different between the two ECGs.]] | [[File:Filter_settings.png|thumb|Filter settings can influence the interpretation of ST elevation as these examples show.
