18.10 6-lead ECG monitoring/12-lead ECG
recording and assessment
Specification
6-lead ECG monitoring/12-lead ECG
recording and assessment
Maximum patient impedance 500 kΩ
Detected heart rate (with ECG derivation via ECG
cable or derivation via defibrillation electrodes)
30 bpm to 250 bpm
Suitability for direct use on the heart Type CF
Displayed heart rates with pacemaker pulses (with
ECG derivation via ECG cable)
If pacemaker pulses are detected, "-" is displayed
instead of the heart rate.
Pacemaker pulses detected by the device:
Amplitude
Pulse width
Overshoots
2 mV to 700 mV
0.5 ms to 2 ms
Detectable at the quoted amplitude and pulse width
in lead I. Pacemaker pulse marking displayed in all
ECG leads.
Device operating mode in the event of a power
supply interruption < 30 s
The device saves all user settings and restores them
when the device is restarted.
Detection of detached electrodes Yes
Noise suppression Yes
Respiration detection No
Max. T wave suppression 0.9 mV
Delay time between R wave detection and shock
delivery
< 60 ms
(measured with Fluke Impulse 7000DP)
Detection range for R wave detection
30 bpm to 180 bpm
0.5 mV to 4.5 mV
Heart rate averaging
The mean heart rate is obtained by averaging up to
7 heartbeat intervals, updated with every heartbeat
or at least every second.
Heart rate accuracy (handling irregular cardiac
rhythms)
All complexes are detected. The heart rate display is
between the shortest and the longest RR interval
detected.
Inputs and input impedance < 2.5 MΩ
Alarm time for tachycardia (acc. to 60601-2-27)
