Pediatric Sinus Node Syndrome

Pediatric sick sinus syndrome (SSS) is an organic disease of the sinoatrial node and atrial conduction system caused by various reasons, which reduces its pacing frequency or egress blockade. Mainly to sinus bradycardia, sinoatrial block, sinus arrest, bradycardia-tachycardia syndrome may also occur. The sinoatrial node has lost the leading role of cardiac pacing, and thus has various arrhythmias, and has clinical symptoms of insufficient blood supply to the heart, brain, and kidneys. Sick sinus node syndrome, also known as sinus node dysfunction, is referred to as sick sinus syndrome or disease sinus. When bradycardia is complicated by cerebral hypoxic syncope or convulsions, it is also called Adams syndrome (Adams syndrome). -Stokes syndrome). Bradycardia and ectopic rapid heart rhythms such as supraventricular tachycardia, atrial flutter, etc., can occur alternately, this is called the fast and slow syndrome. Sick sinuses are less common in children than in adults, and there is no detailed statistics on the incidence.
