The clinical experience with automatic internal defibrillation is now
extensive, with over 65 000 patients treated since the first implantat
ion in 1980. The success of the technique is largely the result of the
perseverance and foresight of Dr. Michel Mirowski, although many peop
le were eventually involved. The author was privileged to participate
almost from the very inception of the project. The early experiments a
nd some of the difficulties along the way leading up to the present ex
tensive favorable human experience are described.
