“…Even development of chronic AF does not subject the atrially paced patients to a mode change to ventricular demand, as long as ventricular response is adequate. 8,10,24) This was shown in one of our patients. In fact, there are arguments that development of stable AF indicates an end stage of sick sinus syndrome and provides a self cure of this disease.17, However, the development and persistence of atrial fibrillation may still present an obstacle to maximal medical control of heart rate in the absence of electrical ventricular support in patients paced atrially only.…”

“…The incidence of atrial fibrillation at initial diagnosis of sick sinus syndi-ome was 8.2 percent or 79 patients, age range i-93 years. Data on the incidence of atrial fibrillation at follow-up were available from 19 studies 1, 3,5,16,21,[23][24][25][26]28,29,33,34,36,38,[39][40][41][42] The total number of patients available for study was 1,171,185 of whom developed atrial fibrillation, or 15.8 percent. The patient-months of follow-up were 44,708; mean follow-up time was 38.2 months.…”

A literature review has addressed the two major factors in disease progression in sick sinus syndrome: atrioventricular block and atrial fibrillation. An incidence of atrioventricular block of 8.4 percent in a follow-up period of 34.2 months is considered clinically significant and sufficient to justify use of a ventricular lead in pacemaker management. Atrial fibrillation occurs much more commonly (22.3%) in ventricular pacing than with atrial demand pacing (3.9%) in a 2 1/2 year observation period. Coincident with the reduction in arrhythmia achieved by atrial demand pacing is a significant reduction in systemic embolism (1.6% vs. 13%). This is considered largely to be due to the improved rhythm control with AAI pacing but also possibly to the avoidance of retrograde atrioventricular conduction. The benefits of AAI pacing in terms of mortality in sick sinus syndrome have not yet been fully assessed. In the future, DDI pacing is recommended with, in some patients, the addition of another sensor to provide rate responsiveness on exercise.

We investigated the course of symptoms and the spontaneous ECG retrospectively in 308 patients who had received a pacemaker because of atrioventricular (AV) block (n = 115), sick sinus syndrome (SSS, n = 107), bradyarrhythmic atrial fibrillation (bradyarrhythmia, n = 51), carotid sinus syndrome (CSS, n = 16), complete bifascicular block associated with 1st degree AV block (n = 13) and with other indications (n = 6). The mean implantation time was 63 months. The clinical state of 93% of all patients improved after pacemaker implantation; their symptoms decreased markedly. Persisting syncopy in some patients with SSS, however, supports a restricted implantation policy. We rarely saw improved AV conduction in patients with AV block (11%). Furthermore, in patients with SSS, atrial fibrillation occurred significantly more often (35%) than in those with AV block (17%; P less than 0.01). Only 3% of patients with SSS developed 2nd and 3rd degree AV block within the observation period. In all patients with initial bifascicular block and additional 1st degree AV block, pacing prevented further syncopal attacks; four of them showed 3rd degree AV block at control, indicating that pacemaker implantation is mandatory in symptomatic patients with bifascicular disease and 1st degree AV block.
