Survival in sinoatrial disorder (sick-sinus syndrome).
A total of 381 patients with established (156) or potential (225) sinoatrial dysfunction were included in a 10-year prospective survey to determine the course of the disease and the benefits of pacing. With the exclusion of nine patients who were lost to follow-up, 61 were fitted with pacemakers. The overall survival of patients with established and potential dysfunction was similar and apparen...
متن کاملPathological studies in sinoatrial disorder (sick sinus syndrome).
Necropsy data from a series of 8 patients diagnosed during life as having chronic sinoatrial disorder (sick sinus syndrome) are presented. The morphology of the cardiac conducting system was studied by serial section, and the coronary vasculature was examined in detail in 5 of the 8 patients by the injection of a radiopaque medium, and in all 8 by routine histological methods.

متن کاملChronic sinoatrial disorder (sick sinus syndrome): a possible result of cardiac ischaemia.

The results were compared with similar studies in 54 subjects who died of heart block and in whom sinus node function was normal (group 2). Although no significant lesion obstructing the blood flow to the sinus node was seen in the majority of tho...
متن کاملRole of autonomic regulatory mechanism in sinoatrial conduction and sinus node automaticity in sick sinus syndrome.
To assess the role of autonomic regulatory mechanisms on sinoatrial conduction and automaticity in patients with clinical evidence of sick sinus syndrome, electrophysiologic studies were conducted in 12 male patients, mean age 64 4 7 years. Heart rate, sinus node recovery time (SNRT) and sinoatrial conduction time (SACT) were determined before and after autonomic blockade with atropine (0.04 mg...
