Dr. Kasperian, a cardiologist from Philadelphia, came to The Allentown Hospital and

the heart. A left thoracotomy to open the chest
wall was performed and the pericardium, the
membrane protecting the heart, was then
opened to expose the heart muscle. An area of
the left ventricle of the heart was selected and
the tips of the electrodes, about one half inch
long, were inserted into the heart muscle and
sutured to prevent their dislodgement.
We placed the pacemaker generator in the
subcutaneous tissue under the clavicle (collarbone) so that it would be accessible when needed
to service the pacemaker in the future. The
temporary wire electrode which had previously
been inserted was removed. The surgery was
successful, the pacemaker was installed, and
worked as expected. Mrs. E's recovery and
convalescence went well, even though her
hospital stay was prolonged until her decubitus
ulcer was adequately healed.

Allentown Hospital at that time. But, fortunately,
