Sick Sinus Syndrome: Sinus Node Dysfunction

Sick sinus syndrome comprises a variety of conditions involving sinus node dysfunction and commonly affects elderly persons. While the syndrome can have many causes, it is usually idiopathic. Patients may experience syncope, pre-syncope, palpitations, or dizziness; however, they are often asymptomatic or have subtle or nonspecific symptoms. Sick sinus syndrome has multiple manifestations on electrocardiogram, including sinus bradycardia, sinus arrest, sinoatrial block, and alternating patterns of bradycardia and tachycardia (bradycardia-tachycardia syndrome). Diagnosis of sick sinus syndrome can be difficult because of its nonspecific symptoms and elusive findings on electrocardiogram or Holter monitor. Pacemaker therapy for sick sinus syndrome is directed at symptoms, not at longevity. The progression of effectively treated sick sinus syndrome is determined by associated heart disease such as myocardial ischemia and left ventricular dysfunction.Keywords: Sick sinus syndrome, sinus node dysfunctionTurkiye Klinikleri J Int Med Sci 2006, 2(24):7-14
