The San Francisco Syncope Rule (SFSR) is a rule for evaluating the risk of adverse outcomes in patients presenting with fainting or syncope. The mnemonic for features of the rule is CHESS: • C - History of congestive heart failure • H - Hematocrit < 30% • E - Abnormal ECG • S - Shortness of breath • S - Triage systolic blood pressure < 90

[1]Orthostatic hypotension occurs when there is a persistent reduction in blood pressure of at least 20mmHg systolic or 10mmHg diastolic within three minutes of standing or being upright to 60 degrees on the head-up tilt table.
In 20% of cases, no cause of death can be found, even after extensive examination.
