The prime goal in cardiac pacemaking is to extend the life of the pulse generator. The Medtronic Model 5945 unit incorporates two modifications which increase pacer longevity: a narrowed pulse width and an improved mercury-zinc cell. We implanted this unit in 21 patients. Although the basic performance of the pacemaker was good, 30 per cent of the patients exhibited muscle inhibition under conditions of extreme stress. Consequently, the sensitivity of ten additional units was reduced to lessen this problem, and the pacemakers were implanted in 10 more patients. Seventeen of the patients from the first group (4 died of causes not related to the pacemaker) have been followed for more than 1 year, and all 10 patients from the second group have been followed for 7 months. The performance of the pulse generators is stable in all. |
