Overview
History
Diagnosing 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. [1]
Symptoms
Patients with mild SSS may be asymptomatic and unaware of any underlying illness. Other patients with symptomatic SSS may experience brief symptoms or more severe manifestations. Some of the symptoms that may develop among patients include: [2]
- Dizziness or light-headedness
- Palpitations
- Chest pain or angina
- Shortness of breath
- Fatigue
- Headache
