Clinical testing of implanted pacemakers.
The function of implanted pacemakers was assessed at a special pacemaker clinic at intervals of three to six months. Measurements of the basic discharge rate of the pacemaker were made and the waveform was recovered from skin electrodes and displayed on an oscilloscope screen. The impulse was photographed from the screen and subsequent waveform analysis was carried out. Reproducible results wer...
متن کاملPermanently Implanted Transvenous Pacemakers
Three patients with complete heart block had a high resistance to electrical stimulation of the endocardium through transvenous pacemaker systems. One patient died; one needed reoperation for implantation of epicardial electrodes; and the third required a generator of higher current. The present enthusiasm for permanent transvenous implantation of pacemakers must be tempered somewhat by the kno...
متن کاملClinical benefits of remote versus transtelephonic monitoring of implanted pacemakers.
OBJECTIVES The purpose of this study was to evaluate remote pacemaker interrogation for the earlier diagnosis of clinically actionable events compared with traditional transtelephonic monitoring and routine in-person evaluation. BACKGROUND Pacemaker patient follow-up procedures have evolved from evaluating devices with little programmability and diagnostic information solely in person to tran...
متن کاملDetection of faults in implanted cardiac pacemakers.
Since 1958, totally implantable pacemakers have been used to stimulate the hearts of patients suffering from chronic heart block. The evidence that such patients have a reduced mortality rate in comparison with unpaced patients (Sowton, 1967) and the ability to return to a normal life have meant that pacemaker implantation for heart block is now accepted practice. There have been increasing num...
متن کاملPrediction of battery depletion in implanted pacemakers.
By the use of a measuring oscilloscope and the standard electrocardiogram limb leads the degree of battery depletion in an implanted pacemaker can be estimated. A formula based on readings obtained by this means has been used to determine when Devices fixed rate pacemakers should be removed. Laboratory tests show that 90% of their useful life is obtained by this means and it proved possible to ...
