Overview
Patients with second degree AV block are asymptomatic. Some patients may present with symptoms of reduced cardiac output. Symptoms include dizziness, fatigue, presyncope or syncope, and light headedness.
History
- History from patients with second degree AV block should involve asking about the following:[1][2]
- Congenital cardiac disease
- Current heart condition
- Recent or previous cardiac procedures
- History of medications
Symptoms
- Most people with Wenckebach (Type I Mobitz) do not show symptoms.[3][4]
- If the sinus rate is slow and only few beats are conducted (higher grade blocks) there may be a significantly reduced cardiac output.
- Usual symptoms in such patients include:[5][6]
