Wolff-Parkinson-White (WPW) and Lown-Ganong-Levine (LGL) syndrome are both characterized by:
- left ventricular dysfunction
- a shortened PR interval
- the presence of delta waves
- large pericardial effusions
- 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.
