[The Italian experience with lithium pacemaker (author's transl)].

After explaining the concept and evolution of lithium-anode batteries, and the various types in use at present as power sources for pulse generators, the Authors examine the Italian studies, including pacemaker's clinical follow-up, technical trials and productions. In fact the first pulse-generators, powered by the best known battery prototypes, i.e. old Lithium-Iodine cell 702 C,P, and E, and Lithium-Silver Chromate cell Li 210 and Li 355, were implanted respectively in 1972, 1973 and 1974, at the Cardiology Department, Ferrara, Italy. The detailed account and analysis of the data supplied by both Italian and Foreign manufacturers, together with the observations furnished by 24 Pacing-Centres--2845 pacemakers implanted for a total amount of 31,794 months/pacemaker out of 8,475 pacemakers supplied for 77,606 months/pacemaker up to June, 30, 1977-indicate a promising future for the development of such pulse-generators. Indeed the latest improved power sources associated with the best and most reliable electronic and electrode pacing systems, already allow the manufactures to produce small, comfortable and long-term pacemakers. Furthermore the significant reduction in periodic controls and replacements, if actually needed, seems sufficient in itself to counterbalance the initial high cost. Thus, medical staff and equipment can be utilized for other purposes.
