In sick sinus syndrome there is a malfunctioning sinus node. Several arrhythmias can result from this:
* Symptomatic slow [[sinusbradycardia]] in the absence of medication
* Symptomatic slow [[sinus bradycardia]] in the absence of medication
* [[Sinusarrest]] or exit block
* [[Sinus arrest]] or exit block
* Combinations of sinoatrial and atrioventricular conductions disturbances
* Combinations of sinoatrial and atrioventricular conduction disturbances
* Brady-tachycardia syndrome; typically there is sinusbradycardia, sinusarrest or SA-block which is alternated by periods with fast or (ir)regular atrial arrhythmias ([[Atrial Fibrillation|atrial fibrillation]], [[Atrial Flutter|atrial flutter]], [[Atrial Tachycardia|atrial tachyardia]] or [[sinustachycardia]]).
* Brady-tachycardia syndrome; typically there is sinus bradycardia, sinus arrest or SA-block which is alternated by periods with fast or (ir)regular atrial arrhythmias ([[Atrial Fibrillation|atrial fibrillation]], [[Atrial Flutter|atrial flutter]], [[Atrial Tachycardia|atrial tachycardia]] or [[sinus tachycardia]]).


Usually a [[pacemaker]] is implanted to prevent bradycardia and tachycardias are 'topped off' with anti-arrhythmics, such as beta blockers.
