Sick sinus syndrome is a disorder of older people and is most commonly seen in people over 70 years of age., he most common cause of sick sinus syndrome is age-related change, like fibrosis, affecting the sinus node (the tiny structure in the right atrium that generates the heart’s electrical impulse). “Fibrosis” means that normal tissue is replaced by a form of scar tissue. The remainder had been followed-up for a total of 217 patient-years. The most troublesome symptom associated with brachy-tachy syndrome is syncope. The signal then travels through the atria to the atrioventricular node and then passes into the ventricles, causing them to contract and pump out blood.
