Long-term atrial pacing for sinus node disease with output-terminal programmable pacemakers

摘要: Long-term transvenous atrial pacing for symptomatic sinus node disease, in the absence of atrioventricular conduction confers advantages increased cardiac performance and probable freedom from systemic thromboembolism. Conventional ventricular has been preferred, however, because complications pacing, mainly those electrical mechanical instability currently available electrodes. These have circumvented with a new pacemaker, programmable output terminal. This allowed institution seven patients, its attendant ability to reprogram noninvasively should fail. Such reprogramming accomplished without difficulty one patient who developed second-degree block electrode microdisplacement.
