Question

Quizplus · Accepted Answer

In second-degree type I block, the impulse is delayed but eventually conducted, resulting in a prolonged PR interval before a dropped beat. The QRS complex is typically not affected by this type of block, so A), QRS, is the correct answer. PVC (B) refers to a premature ventricular contraction, which is not necessarily related to second-degree type I block. ST (C) and AED (D) are also unrelated to this condition.
