Programmable pacemakerとmultiprogrammable pacemaker―その機能と治療効果の検討

抄録

Since 1974, 159 programmable pulse generator (53 rate only PPG, 106 rate and output PPG) and 72 multiprogrammable pulse generator (MPPG) have been implanted in 165 patients with symptomatic bradyarrhythmia, ranging in age from 9 to 90 years (mean age 64.8).
They were classified into 159 VVIP, 68 VVIM, 4 AAIM, following to new classification code (Furman S., 1980).
The rate change were performed for the purpose of improvement of hemodynamics, examination and so on.
In VVIM, the rate (57.4%), pulse width (4.4%), sensitivity (4.4%), hysteresis (2.9%) were programmed.
In AAIM, programmable functions were used to program over two parametors (rate and sensitivity, or rate and pulse width).
PPG and MPPG were more useful than non-PPG. MPPG was more helpful than PPG in clinical use.
