Note:

The fiducial marks displayed in the 4-channel format identify the measurement intervals

used for the interpretive statements of the analysis program. These marks are part of the

analysis program and cannot be turned off.

Printed 12-Lead ECG Frequency Response

The 12-lead ECG can be printed in two diagnostic frequency responses (or bandwidths):

0.05–40 Hz and 0.05–150 Hz. The frequency response of 0.05–150 Hz is the Association for the

Advancement of Medical Instrumentation (AAMI) standard for diagnostic ECGs. The 0.05–40 Hz

setting preserves the low frequency limit that is needed for the diagnosis of myocardial ischemia

and infarction while reducing high frequency artifact (in particular from patient muscle tension) to

help make the diagnostic printout less noisy and more readable.
