Pacer pulse marker independent of pulse polarity
Pulse amplitude between ± 5 mV and ± 700 mV
Heart Rate Indication
Derivation of the heart rate from all ECG signals.
Display range 30 to 300 bpm
Display update with every heart beat, maximum every 2 seconds
Signal Inputs
Isolated patient signal input, IEC type CF, high-voltage protection for all
lead connections and neutral electrode, interference compensation via
neutral electrode, monitoring for open leads.
Electrode connections for R, L, F, N, Cl ... C6, Nax, Nst, Nap (= C4).
Input impedance for differential signals between any two electrode
connections > 10 MW at 10 Hz.
Input impedance for common-mode signals referred to neutral
electrode > 50 MW up to 60 Hz.
Dynamic range for differential signals between any two electrode
connections for AC voltage ±10 mV, for superimposed DC voltage
(polarization voltage) ±600 mV.
Dynamic range for common-mode signals referred to neutral
electrode ±l V, referred to chassis 263 V AC (rms).
Quiescent input current via any electrode connection for l kW
termination referred to neutral electrode < 50 nA.
Patient leakage current (rms values) according to IEC, class CF: in
normal condition < 10 mA, in single-fault condition (e.g. patient in
contact with line voltage) < 20 mA.
Non-destructive range for lead-electrode connections and the neutral
electrode connection referred to neutral electrode ±50 V, referred to
chassis ±1500 V.
Pulse voltage resistance of all lead electrode connections and of the
neutral electrode connection referred to chassis (either polarity, e.g.
defibrillation) 5000 V.
Monitoring of each electrode for open leads: R, L, F, N, Cl, C2, C3,
C4, C5, C6, Nap, Nax, Nst. Audible lead fail signal at program start.
