Procedure:
- predisposition to vasovagal syncope
- heart disease
- systolic BP in the emergency department < 90 or > 180 mm Hg
- serum troponin level > 99th percentile
- abnormal QRS axis (< -30 or > 100 degrees)
- QRS duration > 130 ms
- QTc interval > 480 ms
- emergency department diagnosis of cardiac syncope
- emergency department diagnosis of vasovagal syncope
