2. ECG Wave
ECG General
Lead configuration 12-lead simulation. RL, RA, LA, LL, V1-6
Output impedance Limb leads 1000 ohms to RL
V Leads 1000 ohms to RL
All other signals are in relative proportion to Lead amplitude as follows:
The amplitudes are shown for a Lead I amplitude by 1 mV:
Lead I 1.0 mV (LA - RA)
Lead II 1.5 mV (LL - RA)
Lead III 0.5 mV (LL - LA)
V Lead 1.5 mV (V - 1/3 (LL+LA+RA))
High Level Output (ECG Jack)
1/4" standard phone-jack with an amplitude of 1V/mV of low level Lead
II signal
Defibrillator Contact Plates
Same amplitude as Lead I low level ECG.
1 mV between contact surfaces.
Playback
