SigmaPaceTM 1000: Medtronic Temporary External Pacemaker Model 5388 Checkout Procedure
1. PRELIMINARY SET UP
a. Connect the pacemaker output to the analyzer’s ATRIAL and VENTRICULAR 4 mm interface jacks using the supplied (red and black) test leads.
b. Turn on power on both the pacemaker and the analyzer.
From the main (power-up) menu on the analyzer:
Press F2: INVasive pacemakers
Press F1: NEXT (Tests pacemaker using the default 500 Ω test load.)
Remaining menu navigation directions are given from this Ext-Invasive
Pacer SELECT TEST screen.
Note:
Use the F1: HOLD/RELEASE key feature to freeze test results on the analyzer’s screen.
Use the analyzer’s ESCape key to EXIT out of specific test modes.

|---|---|---|---|---|
| 80 PPM | 1.5 mS | ± 5 % (1.425 – 1.575) | mS |
4. AV INTERVAL
(Use SigmaPace 1000 F1: PULSE OUTPUT, F3: DUAL A+V Screen)
Operational Mode: DDD (Access this feature via the Medtronic 5388 Menu #1 or use it’s power up default output settings.)
Atrial Channel: ON and Ventricular Channel: ON
Atrial Channel Output @ 10 mA
Ventricular Channel Output @ 10 mA
| Rate Setting | AV Interval Setting | Specified Tolerance (mS) | SigmaPace 1000 Reading | Status Pass / Fail? |
|---|---|---|---|---|
| 80 PPM | 20 mS | ± 5 mS (15 – 25) | mS | |
