Key result
In five of six patients implanted with a new multiprogrammable, isotopic-powered cardiac pacemaker, it was advantageous to change a programmable parameter during up to two years of follow-up.
Why the study?
Does a multiprogrammable isotopic-powered cardiac pacemaker allow advantageous parameter changes in patients requiring pacing?

Does a multiprogrammable isotopic-powered cardiac pacemaker allow advantageous parameter changes in patients requiring pacing?
Multiprogrammability in isotopic-powered pacemakers is advantageous for optimizing device parameters over their extended lifespan.
May support parameter optimization in select long-lived isotopic pacemakers; leaves open need for controlled trials before wider use.
A new multiprogrammable, isotopic-powered cardiac pacemaker was implanted in six patients as a custom device. Five were initial implants and one was a replacement. The patients were studied for up to two years. In five of the six cases it was found advantageous to change one of the programmable parameters. Multiprogrammability is obviously as important in an isotopic pulse generator as in a lithium unit, if not more so, because of the unit's greater longevity. Further studies are continuing in an FDA approved clinical trial.
