Table 7-1 ECG Options–First Row (Table continued)Option Description10 mm/mVNOTEThe initial meas-urement dis-played is set inSystem Configu-ration > RestingECG Setup.Changes the magnitude of the ECG signal on the display or in the report. Measurementis in millimeters per millivolt (mm/mV) and includes the following options:• 5 mm/mV• 10 mm/mV• 20 mm/mV• 40 mm/mV• 2.5 mm/mV• AutomaticThe larger the selected measurement, the larger the waveform. Only the representa-tion of the waveform changes; signal strength is not affected.NOTEIf Automatic is selected, the system calculates the best gain based on thepeak-to-peak amplitudes of all displayed leads and the selected displayformat.Changing the measurement here does not change the measurement set in SystemConfiguration.150 HzNOTEThe initial meas-urement dis-played is set inSystem Configu-ration > RestingECG Setup.Eliminates noise in the waveform by restricting which frequencies are included. Fre-quencies are measured in Hertz (Hz) and include the following options:• 20 Hz• 40 Hz• 100 Hz• 150 HzSelecting a frequency eliminates signals that exceed that frequency. The smaller thefrequency selected, the more signal is filtered out. For example, a filter of 40 Hzdisplays only signals at 40 Hz or less; signals greater than 40 Hz are ignored.Changing the measurement here does not change the measurement set in SystemConfiguration.Pace Enhance Improves the readability of pacemaker ECGs. Options are On and Off.More Toggles between the first row of options (previous) and the second row of options(following).Table 7-2 ECG Options–Second RowOption DescriptionPrinter LeadsNOTEThe initial meas-urement displayedis set in SystemConfiguration >Resting ECG Set-up.Selects which leads to include in the printout. Options are:• First 6• Second 6• Rhythm 6• 12Use this option only when conducting rhythm ECGs. For more information, see7.5 Generating a Rhythm Report (Manual Recording) on page 79.Changing the measurement here does not change the measurement set in SystemConfiguration.ADS Toggles the anti-drift system (ADS) on and off. ADS helps reduce baseline drift.Continues on the next pageOperator Manual 7.2 Resting ECGs2053535-002 Revision T MAC 2000 ECG Analysis System 72/198
