Overview
There are no specific laboratory findings associated with First-degree AV block. However, in suspicion of underlying casese of atrioventricular block, laboratory testing about metabolic disorder, infectious disease, rheumatology disorder is reasonable.
Laboratory findings
Laboratory tests in patients with bradycardia or conduction disorder based on the underlying cause may include:
- Thyroid function test in suspicion of hypothyroidism
- Lyme titer in acute Lyme carditis in a young person who develops atrioventricular block in an endemic area
- Potassium level, PH in patients with renal insufficiency
- Blood digoxin level in patients suspected digoxin overdose
