Temporary Pacemakers

The Medtronic 5348 single-chamber temporary pacemaker is a battery-powered temporary pacemaker that was designed to assist in anti-bradycardia pacing therapy. The Medtronic 5348 temporary pacemaker is intended to work with either a cardiac pacing lead system for temporary atrial or temporary ventricular pacing. The system runs on a 9-volt alkaline or lithium battery. This pacemaker emits a current pulse that can maintain a consistent value that is set by the dials on the system. Another single-chamber pacemaker by Medtronic would be the Medtronic 5391.

 

• Easy-to-use operating system.
• Reversible battery polarity makes it easy to change the battery.
• can easily be attached to either a bed or an IV pole.
• Expanded therapy options.
• Increased sensitivity range (0.5 to 20 mV) to provide increased ability to sense p- and r-waves over other devices.
• Provides rapid atrial pacing (to 800 ppm) to better manage atrial flutter.

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, and Medtronic 5832S pacing and surgical cables.

• 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.
