dysfunction.[1] It is characterised by sinus node dysfunction with an atrial rate inappropriate for normal requirements. Sick sinus syndrome is usually caused by idiopathic fibrosis of the sinus node. Causes include:[1]
Sleep apnoea may be a contributing factor by causing reduced cardiac oxygenation. Paediatric causes include congenital abnormalities and sinoatrial nodal artery deficiency. EpidemiologySick sinus syndrome is most common in the elderly, but can occur in all ages. Presentation

Patients may experience atrial flutter and AF as part of this syndrome.
What is a TachyA period of fast heart rates is often followed by very slow heart rates. When there are periods of both slow and fast heart rates (rhythms) the condition often will be called tachy-brady syndrome. Some medicines can make abnormal heart rhythms worse, especially when doses are high.
What type of pacemaker is used for TachyAims: Many tachy-brady syndrome (TBS) patients, are implanted a permanent pacemaker (PPM) to allow continuation of anti-arrhythmic drug (AAD) therapy to maintain sinus rhythm. Many of these PPM's are implanted as a preventive measure, in absence of symptomatic bradycardia.
What is the difference between Tachy and Brady?In tachy-brady syndrome, also called tachycardia-bradycardia syndrome, the heart sometimes beats too quickly (tachy) and sometimes beats too slowly (brady). This abnormal heart rhythm problem is often seen in people who have been diagnosed with atrial fibrillation.
