Traumatic sinus node dysfunction
Annals of Emergency Medicine, 1982A 50-year-old man exhibited sinus node dysfunction following non-penetrating chest trauma. Transiently elevated cardiac isoenzymes, together with normal past electrocardiograms, support the contention that the blunt chest trauma was responsible for the sinus node dysfunction.

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.

Cardiac Electrophysiology Review, 1999
Sinus node dysfunction (SND) is the indication for pacemaker implantation in 35–50% of all patients undergoing primary pacemaker implantation [1]. SND is characterized by syncopal attacks, dizzy spells, or heart failure due to sinus arrest, sino-atrial block, or sinus bradycardia.

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

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.

Sinus node dysfunction complicating viper bite
Asian Cardiovascular and Thoracic Annals, 2013Viper venom toxicities comprise mainly bleeding disorders and nephrotoxicity. Cardiotoxicity is a rare manifestation of viper bite. We describe the case of a previously healthy 35-year-old man who developed coagulopathy and sinus node dysfunction following a viper bite. Electrocardiography showed sinus arrest and junctional escape rhythm.

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.

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 ...

Ropinirole‐Induced Symptomatic Sinus Node Dysfunction
Pacing and Clinical Electrophysiology, 2008Restless legs syndrome is a neurological disorder that can be treated with ropinirole. We report the case of a patient who presented with syncope during treatment with ropinirole due to prolonged sinus pauses. The treatment was discontinued and the patient remained asymptomatic.
