Electrocardiogram (ECG)

Input.........................................: Isolated; IEC type CF; for ECG leads with 3, 4 or 5 electrodes; colour-coded red.
Input impedance .......................: > 20 MΩ at 10 Hz
Leads .......................................: 1, 2, 3 or I, II, III, AVR, AVL, AVF, V
Display .....................................: Position can be configured as required.
Input voltage.............................: Max. 6 mV peak
Graph display ...........................: 0.5 to 8 mV
DC offset..................................: Max. 300 mV (only if filter set to »On«)
Bandwidth ................................: 0.5 to 30 Hz (– 3 dB) with filter set to »On«
Interference suppression
(50/60 Hz)................................: With ECG lead and 5 kohm unbalanced: > 127 dB
Output impedance ....................: < 10 Ω, output current < 1 mA, short-circuit-proof.
Noise........................................: < 25 µVpp with an impedance of 51 kΩ // 0.047 µF to each neutral line per electrode.
Zero stabilization.......................: Automatic; when mean peak value exceeds display range.
Stabilization time.......................: < 0.5 s; artefact message and alarm after 15 seconds.
Pacemaker pulses ....................: Automatically magnified on display when detection function active. Not counted in
Defibrillator ...............................: Protected against defibrillation shocks; synchronization pulse available.
Heart rate/pulse rate
Source of heart rate/pulse rate..: Derived from the 1st ECG, SpO
Heart beat indication.................: Acoustic and visual; acoustic indication derived from SpO
Frequency ................................: Over approx. 10 beats on average.
Measuring range.......................: 30 to 300 beats per minute.
Accuracy ..................................: 1 beat/minute or 1%.
Resolution ................................: 1 beat/minute
Pulse deficit indication ..............: Difference between heart rate (derived from ECG) and pulse rate
Detection of asystole/
ventricular fibrilation ..................: Cannot be deactivated; asystole alarm after 6 seconds; ventricular fibrillation
S-T segment analysis................: Amplitude:
> 4 MΩ at 40 Hz
0.05 to 70 Hz (– 3 dB) with filter »Off«
