Contributor: Don Stader, MD
Educational Pearls:
- Syncope is usually benign but can be caused by serious etiologies which include: PE, certain cardiac arrhythmias, AAA, intracranial bleed/stroke
- The Canadian Syncope Rule appears to identify those patients with syncope and low risk of serious outcomes
- The score is based on vital signs, EKG and history
- Negative scores preclude a very low risk of adverse events
- A calculated score greater than 1 are considered medium risk
- Scores greater than 4 are high risk
- Anyone with a medium risk or higher should have their cause thoroughly investigated - which may involve admission or a shared decision making utilizing this rule if discharged
Editor's note: just remember this rule has not been externally validated… yet
