Radioisotope Powered Cardiac Pacemakers.
Over 100,000 implantable cardiac pacemakers are currently being used to rehabilitate patients with heart block. The chemical batteries powering these pacemakers usually fail within a few years. A variety of nuclear batteries with the potential of providing long-lived (10-20 years) pacemaker power, are under development. This paper reviews the status of this development. Nuclear powered pacemake...
متن کاملErosive Pressure Dermatitis Associated with Cardiac Pacemaker
Erosive dermatitis is a skin reaction associated with implantable cardiac devices (ie, pacemakers and cardioverter defibrillators). We report a 65-year-old man with a history of several cerebrovascular attacks who developed an erythematous crusted erosive patch over the pacemaker site after implantation of two subsequent pacemakers. We suggest that physical irritation may be a trigger factor fo...
متن کاملLong-term evaluation of the General Electric cardiac pacemaker.
A review of General Electric (G.E.) electronic cardiac pacemakers for symptomatic complete A-V heart 'block in two sequential three-year periods at the University of Michigan Medical Center indicates that there has been no increase in the useful life of these units. With G.E. epicardiall pacemakers failure occurred after an average of 12 months. In the early years the major cause of failure was...
متن کاملA gradient model of cardiac pacemaker myocytes.
We have formulated a spatial-gradient model of action potential heterogeneity within the rabbit sinoatrial node (SAN), based on cell-specific ionic models of electrical activity from its central and peripheral regions. The ionic models are derived from a generic cell model, incorporating five background and exchange currents, and seven time-dependent currents based on three- or four-state Marko...
متن کاملAn intragastric cardiac pacemaker.
A 62-year-old housewife was seen in May 1967 with attacks of dizziness and loss of consciousness. A diagnosis of complete heart block with Stokes-Adams syncope was made. Anterolateral thoracotomy was performed and myocardial electrodes were inserted over the left ventricle and were connected to a Devices fixed-rate pacemaker, inserted in the rectus sheath posterior to the rectus muscle. Postope...
