SigmaPace 1000 App Note: Medtronic Temporary External Pacemaker Model 5388 Checkout Procedure 

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.

120 PPM ± 5 % (114 – 126) 475 – 525 PPM  
200 PPM ± 5 % (190 – 210) 285 – 315 PPM  

 

c. RAPID ATRIAL RATE (RAP)

(Use SigmaPace 1000 F1: PULSE OUTPUT, F3: DUAL A+V Screen)
Operational Mode: AOO (Access RAP feature via the Medtronic 5388 Menu #3).
Atrial Channel: ON and Ventricular Channel: OFF
Atrial Channel Output @ 10 mA

 

Rate Setting Specified Tolerance (PPM) Specified Tolerance (mS) SigmaPace 1000 Reading Status Pass / Fail?
350 PPM ± 5 % (285 – 367.5) 163 – 180 PPM  

 

3. PULSE WIDTH

a. ATRIAL PULSE WIDTH
(Use SigmaPace 1000 F1: PULSE OUTPUT, F3: DUAL A+V Screen)
Operational Mode: AAI
Atrial Channel: ON and Ventricular Channel: OFF
Atrial Channel Output @ 10 mA

 

Rate Setting Pulse Width Specified Tolerance (mS) SigmaPace 1000 Reading Status Pass / Fail?
80 PPM 1.0 mS ± 5 % (0.95 – 1.05) mS  

 

b. VENTRICULAR PULSE WIDTH
(Use SigmaPace 1000 F1: PULSE OUTPUT, F3: DUAL A+V Screen)
Operational Mode: VVI
Atrial Channel: OFF and Ventricular Channel: ON
Ventricular Channel Output @ 10 mA

 

Rate Setting Pulse Width Specified Tolerance (mS) SigmaPace 1000 Reading Status Pass / Fail?
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  
80 PPM 150 mS ± 5 % (142 – 158) mS  
80 PPM 300 mS* ± 5 % (285 – 315) mS  

*To set the Medtronic 5388 AV interval @ 300 mS, first decrease the PVARP to minimum (150 mS) on MENU #2 and then go to Menu #1 to access the AV interval function.
