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 of cardiac disease both current and congenital, recent cardiac procedures and current medications. Patients with Mobitz type II often present with fatigue, dyspnea, chest pain, presyncope or syncope, and even sudden cardiac arrest.Patients who have severe bradycardia resulting in hypotension and decreased cardiac output may be diaphoretic and pale. Patients who have a second-degree atrioventricular block secondary to myocardial ischemia may present with chest pain.
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][4]:
- Light-headedness
- Dizziness
- Fainting
- Fatigue
- Heart failure symptoms
- Pre-syncope
- Syncope
