Sinus node dysfunction (SND) was first time described in 1968 by Ferrer under the name of sick sinus syndrome and refers to abnormalities in sinus node impulse formation and propagation and includes sinus bradycardia, sinus pause, chronotropic incompetence, and sinoatrial exit block.The most dramatic symptom in patients with SND is syncope.About 50% of patients with SND develop tachy-brady syndrome over a lifetime; such patients have higher risk of stroke and death.Incidence of sudden death owing directly to SND is extremely low.
