Welch Allyn CP 200 Electrocardiograph
Caution The requirements of AAMI EC11, Section 3.2.7 .2, Frequency and
Impulse Response, for an impulse triangle waveform may be impacted by up to 5
milliseconds of small amplitude dampened ringing immediately after the impulse
when the muscle filter (35 Hz) is turned on or a small amplitude offset when the
baseline filter (0.5 Hz) is turned on. These requirements are unaffected by any
other combination of filters turned on or off. Measurements performed by the
optional interpretation algorithm are unaffected by any filter selections.
