Sinus pause or arrest. Sinoatrial (SA) exit block. Sinus node dysfunction affects mainly older patients, especially those with another cardiac disorder or diabetes. Sinus pause is temporary cessation of sinus node activity, seen on electrocardiography (ECG) as disappearance of P waves for seconds to minutes.

Prognosis In vivo, pacemaking activity of the SA node is constantly modulated by an input from autonomic nervous system. Prolonged CSNRT in db/db mice would suggest intrinsic nodal abnormalities, but we suspected that SA nodal dysfunction may be extrinsic as it is not evident at the baseline ECG but is unmasked by adrenergic stimulation. Sinus node dysfunction refers to the pathologic affection of the sinus node. When symptomatic it is referred to as the sick sinus syndrome.

Sick sinus syndrome is not a disease with a single etiology and pathogenesis but, rather, a collection of conditions in which the electrocardiogram (ECG) indicates sinus node dysfunction. 2 Sick SA Dysfunction is a sign of diseased tissue around the sino-atrial node. This may be damage secondary to an MI , or to a degenerative ageing process affecting the node.

ECG; A slow, irregular pulse suggests the diagnosis of sinus node dysfunction, which is confirmed by ECG, rhythm strip, or continuous 24-hour ECG recording. Some patients present with atrial fibrillation (AF), and the underlying sinus node dysfunction manifests only after conversion to sinus rhythm. Prognosis 2005-09-01 Sinus Node Dysfunction at Life in the Fast Lane.

This manifests with loss of P-waves (loss of atrial activation) and consequently loss of QRS complexes (loss of ventricular depolarization). Sinus Node Dysfunction Refers to problems with sinus node impulse formation and propagation May include sinus bradycarda, sinus pauses or arrest, chronotropic incompetence, and sino-atrial exit block When accompanied by symptoms it is referred to as Sick Sinus Syndrome INTRODUCTION Sinus node dysfunction (SND), also historically referred to as sick sinus syndrome (SSS) is characterized by dysfunction of the sinoatrial (SA) node that is often secondary to senescence of the SA node and surrounding atrial myocardium.
