St.Jude Medical External Pulse Generator single chamber ( model-3077)

>The Model 3077 single-chamber external pulse generator (temporary pacemaker) is designed for safe and reliable temporary stimulation of the heart in cases of rhythm disturbances and conduction defects.

 >An extensive single-chamber feature set offers:

– Mode choices of Off, AAI/VVI (inhibited operation), and AAI/VVI Beep (inhibited operation with acoustic signals during sensing and pacing), along with asynchronous pacing.

– A base pacing rate range of 30-180 ppm for appropriate pacing support for all therapy needs, including those of pediatric patients.

– Adjustable pulse amplitude and sensitivity parameters.

– Two modes of high-rate pacing (x 2 and x 4) available for treatment of atrial tachycardia (which multiply the set pacing rate by the indicated factor with the press of a button.)

>Up to 12 volts of output available per channel make the Model 3077 temporary pacemaker one of the highest-output devices of its kind available. 

>Advanced circuitry promotes efficiency, allowing for good battery longevity.

>Standard 9 volt lithium or alkaline batteries are used, and the device features both visual and audible battery life indicators.

>Runaway protection limits the device to a maximum rate of 200 ppm in the unlikely event of circuit malfunction.

>Both intrinsic and paced activity is indicated with separate blinking LEDs; an audible tone can be added if desired.

>Large, simple dial controls promote ease of use.

>Small size and lightweight design make the Model 3077 temporary pacemaker easy to store and transport.
