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. Although the sinus node depolarises normally, there is intermittent failure of that impulse being conducted through the atrial tissue. When the sinus node generates an electrical impulse, the surrounding cells of the right atrium depolarize.

Some patients present with atrial fibrillation (AF), and the underlying sinus node dysfunction manifests only after conversion to sinus rhythm. A primary manifestation of SA nodal dysfunction is disordered automaticity, where the slope of phase 4 automaticity is reduced in the SA node, resulting in bradycardia. The test designed to assess SA nodal automaticity in the electrophysiology laboratory is the “sinus node recovery time” (SNRT; Figures 5.1 and 5.2 ). Sinus Node Dysfunction at Life in the Fast Lane.
