Acta Medica Scandinavica, 1976
ABSTRACT Clinical and electrophysiological characteristics have been investigated in a group of 30 patients with a sick sinus syndrome. No predictable response to exercise or drugs was observed, although a poor response of the sinus rate to atropine was present.

A novel homozygous SCN5A variant detected in sick sinus syndrome
Pacing and clinical electrophysiology : PACE, 2020Sick sinus syndrome (SSS) is a group of disorders characterized by an abnormal cardiac impulse formation or propagation from the sinoatrial node. Mutated SCN5A has been reported in SSS, however, homozygosity of SCN5A is exceedingly rare.

Sinus-node dysfunction is common in the elderly and, in most cases, does not cause any symptoms. Despite the high number of laboratory investigations, most diagnoses of sinus-node dysfunction are made by 12-lead electrocardiography, which shows severe sinus bradycardia, sinus arrest, or sinoatrial block.

The sick-sinus syndrome in Africans
American Heart Journal, 1975Fifteen cases of the sick-sinus syndrome in young Negroes are presented. The etiology was unknown in all cases; organic heart disease was absent. The very high default rate suggests that the prognosis may be grave. This disorder is by no means uncommon in young persons in tropical countries and the dangers of a mistaken diagnosis of epilepsy or a ...

Heart rate variability in sick sinus syndrome: does it have a diagnostic role?
Minerva Cardioangiologica : a Journal on Cardiovascular Pathophysiology, Clinical Medicine and Therapy, 2019BACKGROUND Hypothesis of our study was that the irregular rhythm of sick sinus syndrome (SSS) was characterized by an augmented HRV. Objective was to assess whether SSS patients had a typical HRV profile. METHODS We screened all 1947 consecutive Holter

Pacing for Carotid Sinus Syndrome and Sick Sinus Syndrome
Pacing and Clinical Electrophysiology, 1990BRIGNOLE, M., ET AL: Pacing for Carotid Sinus Syndrome and Sick Sinus Syndrome.The real incidence of pacemaker implants for carotid sinus syndrome (CSS) and the relation between CSS and sick sinus syndrome (SSS) is not precisely known. Patients who needed pacing therapy because of atrial bradyarrhythmias were investigated by means of carotid sinus ...

The commonly used term sick sinus syndrome refers to a constellation of disorders of sinus rhythm that includes (1) inappropriate sinus bradycardia, (2) barious forms of sinoatrial block, (3) sinus arrest, (4) tachycardia-bradycardia syndrome, (5) sinoatrial nodal suppression by ectopic beats, and (6) sinoatrial reentry.

A Case of the Sick Sinus Syndrome
Gerontologia Clinica, 1973Blackouts and giddy attacks are frequent problems for the geriatrician to solve. A case of the recently discovered sick sinus syndrome is described. Its diagnosis led to the insertion of a pacemaker, whereafter the patient has been completely symptom-free. This report aims at bringing this newly recognized syndrome to the attention of geriatricians and

The Natural History of Sick Sinus Syndrome
Pacing and Clinical Electrophysiology, 1986A 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.
