A new radioisotope-powered cardiac pacer
DL Purdy, GJ Magovern and NP Smyth
A small lighweight nuclear pacer is described. The unit weighs 6) Gm. and
occupies a bolume of 33 c.c. It is a standard, R-wave inhibited, demand
pacer and has been shown to be insensitive to electromagnetic interference.
The unit has met all United States and Foreign Atomic Energy Commission
(AEC) safety specification requirements, including cechanical shock,
industrial fire, accidental crush, cremation, impact, and corrosion. Its
calculated life is in excess of 20 years. Extensive dog testing has been
completed and will be described in detail elsewhere. The United States AEC
has been issued a license to conduct extensive clinical trials. These began
in October 1974, and will be the subject of a later report.
