Which statement best describes 1st degree AV block management?

• A. It is typically benign and often requires no treatment
• B. It always progresses to higher-degree blocks
• C. It requires immediate pacing
• D. It is characterized by dropped QRS complexes

Answer: (A)

First-degree AV block is a conduction delay where every atrial impulse still reaches the ventricle, but with a consistently prolonged PR interval. Because there are no dropped QRS complexes and patients are often asymptomatic, this finding is usually benign and requires no treatment. The usual approach is observation and addressing any reversible causes, such as medications that slow AV nodal conduction or electrolyte abnormalities. Pacing is reserved for cases with symptoms of bradycardia or progression to a higher-degree block. The presence of dropped QRS complexes would point to higher-grade blocks, not first-degree. So, the statement that it is typically benign and often requires no treatment best describes management.
