Performance Characteristics Appendix
19 - 10 0070- 0-0704-02 Passport V Operating Instructions
Pace Pulse Rejection
• HR calculation rejects pulses with amplitude between ±2mV to ± 700 mV and width
between 0.1 ms and 2 ms (no tails).
• To enable about 50% pace pulses with fig.5d (EC13, at page 28) waveforms to trigger
pace pulse detector, the minimum input waveform change rate is 50 V/s RTI.
ECG Specifications
Mortara Arrhythmia ( V3.2 )
•HR range
• 15 BPM to 300 BPM Adult,
• 15 BPM to 350 BPM pediatric,
• 15 BPM to 350 BPM neonatal
Accuracy: '+/- 5 % for heart rates between 251 BPM' and 350 BPM, the greater of
'+/- 3 BPM' or 3% for heart rates between 30 BPM and 250 BPM'
Tall T waves Rejection
• Complies with 4.1.2.1 c of ANSI/AAMI EC13-2002.
• HR calculation is not affected for T-waves whose QRS complex is 100ms, QT interval is
350ms, lasting time is 180ms and amplitude less than 1.2mv.
ST Segment Analysis
• Scope: ST analysis is available for Adult and Pediatric patients only.
• ST Measurement Point
• ST measurement point can be manually adjusted: J+60 and J+80 (default: J+60 ms).
• ISO point can be manually adjusted: from 4 to 200 ms before R waves (default: 80ms)
and adjusted interval: 4ms.
• J point can be manually adjusted: from 4 to 200 ms after R waves (default: 48ms).
• Real Time Reference of ST Segment Analysis: Supported.
• Refresh Rate of ST Reference: 16 beats.
Arrhythmia Analysis
• Scope: Arrhythmia analysis is available for Adult and Pediatric patients only.
• Arrhythmia Type: 11 kinds of Arrhythmia events are included:
ASYSTOLE, V-FIB, V-TACH, VRHYTHM, COUPLET, RUN, BIGEMINY, TRIGEMINY,
IRREGULAR HR, BRADY, PVCs per minute
