The Daily PANCE and PANRE Question 54

Wolff-Parkinson-White (WPW) and Lown-Ganong-Levine (LGL) syndrome are both characterized by:

  1. left ventricular dysfunction
  2. a shortened PR interval
  3. the presence of delta waves
  4. large pericardial effusions
  5. marked left ventricular hypertrophy

Answer: B

Shortened PR interval

Wolff-Parkinson-White (WPW) and Lown-Ganong-Levine (LGL) both have short PR intervals. WPW also has a "delta wave" and predisposes the patient to supraventricular tachyarrhythmias.
