The nurse notes the following when analyzing a patient's teleme-
try strip: HR, 65/min and regular; PR interval, 0.22 seconds; QRS QT measurements reflect the duration of ventricular repolar-
complex, 0.10 seconds; QTc, 0.52 seconds. Which of the following ization. Lengthening of QT interval is associated with arrhyth-

longer QT duration places the vulnerable ventricular repolarization
A. Atrial fibrillation because the PR interval is wide phase close to the next depolarization, increasing the likelihood of

D. Third-degree heart block because the PR interval is narrow and third-degree heart block are not typically associated with
