The nurse notes the following when analyzing a patient's telemetry strip: HR, 65/min
and regular; PR interval, 0.22 seconds; QRS complex, 0.10 seconds; QTc, 0.52
seconds. Which of the following dysrhythmias is the patient at risk for?
A. Atrial fibrillation because the PR interval is wide
B. Sinus arrhythmia because the QRS complex is narrow
C. Torsades de pointes because the QTc is wide
D. Third-degree heart block because the PR interval is narrow

, C.
QT measurements reflect the duration of ventricular repolarization.
Lengthening of QT interval is associated with arrhythmias, adverse cardiac
events, and increased mortality because a longer QT duration places the
vulnerable ventricular repolarization phase close to the next
depolarization, increasing the likelihood of R-on-T. The most common
arrhythmia that occurs with prolonged QTc is torsades de pointes. Atrial
fibrillation, sinus bradycardia, and third-degree heart block are not typically
associated with prolonged ventricular repolarization (QTc >0.50 seconds).
