Overview
Natural History, Complications and Prognosis
Natural History
- Sinus bradycardia occurs in healthy patients as an adaptive response, particularly in well-conditioned persons or while sleeping, but it can also occur as a pathologic response in a variety of conditions.
- Sinus bradycardia itself does not cause symptoms directly, although a patient with comorbid conditions that may be exacerbated by decreased cardiac output (e.g. angina, heart failure) may have worsening symptoms related to comorbidity.
- Slower sinus rates are often very well tolerated. Asymptomatic resting bradycardias, particularly in trained athletes and young individuals are not pathological and doesn't require treatment.
Complications
- Common complications of bradycardia include:[1]
Prognosis
The prognosis is good when the rhythm is quickly identified by the healthcare provider. Nevertheless, people with sick sinus syndrome who have bradycardia appear to have a poor 5-year survival prognosis of 45-70 per cent.[2]
