Overview
Common causes of first-degree AV block include ischemic heart disease, degenerative conduction system disease, congenital heart disease, connective tissue disease, inflammatory diseases, medications (digitalis glycosides, β-blockers, calcium channel blockers), hyperkalemia, and increased vagal tone.
Causes
Life Threatening Causes
Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.
Common Causes
- Hyperkalemia
- Hyperthyroidism
- Increased vagal tone (e.g. sleep, athletes)
- Ischemic heart disease
- Medications ( e.g. adenosine, amiodarone, beta-blockers, diltiazem, procainamide, verapamil)
