Real-Time ECG Analog/Defib Sync
Propaq Encore Reference Guide 139 Welch Allyn
Real-Time ECG Analog/Defib Sync
Special cables are required to interface the defib sync connector to the Physio-Control
LIFEPAK 5 or LIFEPAK 6s defibrillator.
Real-Time ECG Analog/Defib Sync Signals
The sync and real-time ECG outputs do not operate during In-service mode.
Signal Specification
Sync Output 0 to 5V pulse, 100 ±5ms wide, starts within 35 ms after peak of R-
wave. 15 mA short circuit current.
Real-time ECG Output Range = ±6V minimum, centered about 0V, Gain = 1000X,
noninverting for lead II, inverting for all other leads, delay <3 msec,
0.05-100 Hz, going to -5.9V ±5% during ECG lead fail. V lead has no
Real-Time analog output.
Marker Input (Defib Sync only) Normally 0V in, a pulse either + or -3 to ±15V for 10-70 ms puts a
marker in ECG trace. ~ 5 kΩ input res.
