Specifications
Maximum T-Wave amplitude: Device rejects up to 80% of R-Wave amplitude for synchronized
cardioversion; up to 55% of R-Wave amplitude for demand pacing; up to 34% of R-Wave
amplitude for arrhythmia analysis. Maximum T-wave amplitude when a QRS test signal is 1 mV
amplitude and 100 ms duration, with a heart rate of 80 1/min used: 18mm.
Frequency Response:
ECG AC Line Filter: 50 Hz or 60 Hz.
ECG for Display: 0.15-40 Hz, 0.05-40 Hz (EN 60601-2-27:2006 50.102.8 a, b), 2.0-20.0 Hz
ECG for Printer: 0.05-150 Hz - Diagnostic, 0.15-40 Hz - ST Monitor, 0.05-40 Hz - Monitor
(EN 60601-2-27:2006 50.102.8 a, b), 2.0-20.0 Hz - EMS
Heart rate accuracy and response to irregular rhythm: Meets AAMI standard for ventricular
bigeminy (HR=80 bpm); slow alternating ventricular bigeminy (HR=60 bpm); rapid alternating
ventricular bigeminy (HR=120 bpm); bidirectional systoles (HR=90 bpm) as measured after a 20 sec
stabilization time.
Heart rate averaging: For heart rates ≥ 50 bpm, heart rate is determined by averaging the 12 most
recent R-R intervals. Beats N, P, and V are included. When heart rate drops below 50 bpm, the four
most recent R-R intervals are used in the average. Note: For ventricular tachycardia alarms, which
have a user-definable PVC run length limit, the heart rate is based on the user-selected PVC length
up to 9 PVCs maximum. Heart rate display update time is 1 second maximum.
Pace Pulse Detection Sensitivity: 1 mV for a width of 100 µs; 200 µV for a 500 µs width and 200
µV for widths of 500 µs to 2 ms.
ECG Analog Output Bandwidth: 0.5 to 70 Hz
ECG Analog Output Gain: 1v output per 1mV input ±10%
ECG Analog Output Delay: Propagation delay time is <25ms from ECG input to ECG analog
output.
Pacemaker Pulse Rejection Capability: Amplitude from ± 2 mV to ± 700 mV, width from 0.1 ms to
2.0 ms as per ANSI/AAMI EC 13:2002 4.1.4.1/YY1079 4.1.4.1, except the full overshoot range of
IEC 60601-2-27/GB9706.25 methods A and B.
Pacer Pulse Detector rejection of Fast ECG Signals: Slew Rate of 1.1 V/s.
Heart Rate Response Time: 7 sec for a High Heart Rate alarm when the rate changes from 80 to
120 bpm, with the alarm limit set at 100 bpm; 6 sec for a Low Heart Rate alarm when the rate
changes from 80 to 40 bpm, with the alarm limit set at 60 bpm.
Time to Alarm for Tachycardia: 4 sec for 206 bpm (1 mV, halved amplitude and double amplitude)
and 195 bpm (2 mV, halved amplitude and double amplitude) as measured following a normal 80
bpm rate with upper alarm limit set at 100 and lower alarm limit set at 60 bpm.
