Second degree AV block physical examination

Patients with second degree AV block are usually asymptomatic. However, patients with previous chronic cardiac condition may appear in a distress. In symptomatic patients, common physical examination findings include bradycardia, hypotension, and syncope. Physical examination in patients with heart failure may include lung crackles, jugular venous distension, and peripheral edema.

• Patients may appear pale in cases of bradycardia with decreased cardiac output.^[3]

• Bradycardia with an irregular pulse^[4]
