Overview
Diagnosing sick sinus syndrome (SSS) can often be challenging due to nonspecific symptoms and inconsistent findings on electrocardiogram or Holter monitor. Patients may be asymptomatic and the finding incidental or present with symptoms related to decreased cardiac output. 50 percent of patients present with syncope or pre-syncope related to the decreased cerebral perfusion secondary to bradyarrhythmias or tachyarrhythmias. Some of the symptoms that may develop among patients include memory loss, dizziness or light-headedness, Palpitations, chest pain or angina, shortness of breath, fatigue, and headache.
