Sinus node dysfunction, previously known as sick sinus syndrome, describes disorders related to abnormal conduction and propagation of electrical impulses at the sinoatrial node. An abnormal atrial rate may result in the inability to meet physiologic demands, especially during periods of stress or physical activity.

Sinus Node Function and Dysfunction
Medical Clinics of North America, 1984The wide range of normal sinus node function makes identification of dysfunction difficult. Emphasis is placed upon real time correlation of ECG bradyarrhythmia with typical symptoms. A spectrum of atrial electrical dysfunction is described which includes abnormalities of the sinus and AV nodes as well as failure of escape pacemakers and atrial ...

Sinus Node Dysfunction in Tuberous Sclerosis
Pediatric Cardiology, 1996Tuberous sclerosis is an autosomal dominant disease with potential for involvement of the skin, brain, lungs, kidneys, and heart. A case of prolonged sinus node pause and episodes of unresponsiveness in a 21-week-old infant with tuberous sclerosis is described. The infant subsequently underwent placement of an epicardial pacemaker.

Progress in Pediatric Cardiology, 1994
Abstract One or more abnormal findings on several noninvasive or invasive tests is sufficient for the diagnosis of sinus node dysfunction in children. Invasive testing is seldom required. Presentation of the patient with sinus node dysfunction is variable and depends on patient age, presence of underlying hemodynamic disease, presence and severity of

Arrhythmias and Sinus Node Dysfunction
JAMA: The Journal of the American Medical Association, 1984To the Editor. — Alpert and Flaker1have contributed an excellent review of arrhythmias associated with sinus node dysfunction. I wish to take exception to only one item, which, unfortunately, is a recurring source of confusion in many publications. In the author's Table 1, they list acute pericarditis as a cause of sinus node dysfunction.

Sleep Apnea and Sinus Node Dysfunction
JAMA: The Journal of the American Medical Association, 1984To the Editor.— I read with interest the recent article by Drs Alpert and Flaker 1 on sinus node dysfunction. However, I was surprised to find no mention of a relatively common, easily treatable condition that is associated with reversible sinus arrhythmias.

Bradycardia: sinus and AV node dysfunction
Herzschrittmachertherapie + Elektrophysiologie, 2015The surface electrocardiogram (ECG) holds many clues with regard to the etiology of bradycardia and site of atrioventricular (AV) block. Bedside maneuvers may prove helpful in cases of 2:1 AV block or situations where the data is not all concordant. Wenckebach conduction may occur in any region of the heart, and there are nonpathologic mimickers of ...

Unmasking of sinus node dysfunction by ajmaline
International Journal of Cardiology, 1989A 75-year-old male with bifascicular block presented with recurrent giddiness and presyncope. Prolonged monitoring of the cardiac rhythm did not reveal any arrhythmia. Electrophysiological evaluation, including an ajmaline stress test, was performed. Ajmaline had an unusual effect.

Fetal Bradycardia and Sinus Node Dysfunction [PDF]
Pediatric Cardiology, 2012 The study reported here is a rare case of fetal sinus bradycardia that evolved into symptomatic bradycardia after birth, at which time the implantation of a cardiac pacemaker was indicated. Fetal echocardiography was used to diagnose the type of cardiac rhythm that caused the intra-uterine bradycardia, which enabled the initiation of the appropriate ...

Xamoterol in autonomic and intrinsic sinus node dysfunction
The American Journal of Cardiology, 1990Abstract In a recent study, pindolol, due to its intrinsic sympathomimetic activity or partial agonism, appeared to be of some benefit in the treatment of sinus node (SN) dysfunction. 1 Xamoterol is a cardioselective β-adrenoceptor partial agonist.
