Abstract

Abstract: Sinus node dysfunction (SND) refers to a wide range of abnormalities involving sinus node and atrial impulse generation and propagation. SND occurs at any age and is commonly encountered in clinical practice. Clinicians must be able to accurately diagnose this syndrome, which can present from asymptomatic bradycardia to atrial standstill.
