The Medtronic 5388 is a dual-chamber temporary pacemaker that provides eight different types of modes for pacing therapy. This Medtronic pacemaker is battery-powered and usually connected to transvenous, epicardial, or myocardial pacing leads. It can be used for temporary single or dual-chamber pacing. Its constant current device, the pulse emitted from the device stays at a constant value. Medtronic offers a few different dual chamber pacemakers including the Medtronic 5392.

• Operates with a 9V alkaline or lithium battery.
• DDD, DVI, DDI, DOO, VOO, VVI, AOO, and AAI pacing therapy modes.
• Compatible with Medtronic 5433A, Medtronic M5433V, Medtronic 5832, Medtronic 5832S pacing and surgical cables.

• Height: 8.3 in. (21.1 cm) ± 15%
• Width: 3.2 in. (8.1 cm) ± 15%
• Depth (without dials): 1.4 in. (3.6 cm) ± 15%
• Weight (with battery): 510 g (18 oz.) maximum

Battery

• Type: 9 V Alkaline, type 6LR61, type 6F22E, NEDA 1604A; 9 V Lithium, NEDA 1604LC (Ultralife U9VL or equivalent)
• Life: 9 days typical, 7 days minimum (alkaline), or 16 days (lithium)

Modes

• Modes: AOO, AAI, VOO, VVI, DOO, DDD, DDI, DVI

Rates

• Base Rate: 30 – 200 min-1 ± 5%
• Rapid Atrial Pacing Rate: 80 – 800 min-1 ± 5%

Pulse Width

• Atrial: 1.0 ms ± 10%
• Ventricular: 1.5 ms ± 10%

Sensitivity

• Atrial ASYNC: 0.4 – 10 mV ± 0.3 mV or 25%
• Ventricular ASYNC: 0.8 – 20 mV ± 0.3 mV or 25%

A-V Interval

• Auto: 50 – 250 ms
• Manual: 20 – 300 ms ± 5 ms or 5%

Refractory Period

• Atrial (At atrial event): 250 ms ± 10%
• Ventricular: 250 ms ± 10%

Upper Rate

• Auto (base rate): + 30 min-1 ± 10%
• Manual: 80 – 230 min-1 ± 10%

Rate Limit

• A crystal is used to set the pacing rate. If the crystal rate deviates from the appropriate value, the rate runaway protection circuit resets the device once. If the crystal rate remains incorrect, the rate of runaway protection circuit turns the device off.

Temperature Conditions

• Operating: 64°F to 92°F (17°C to 33°C)
• Storage (without battery): -40°F to 158°F (-40°C to 70°C)
