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.
Symptoms
- Most people with Wenckebach (Type I Mobitz) do not show symptoms.[1][2]
- 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[3]:
- Light-headedness
- Dizziness
- Fainting
- Fatigue
- Heart failure symptoms
- Pre-syncope
- Syncope
