Identify those at low risk of adverse outcome after a syncopal episode
The San Francisco Syncope rule identifies patients who cannot be considered low risk of adverse outcomes after a syncopal event.
Criteria include:
If any of these criteria are noted, patient cannot be considered "low risk" of a serious outcome. In this study, a serious outcome is defined as "death, myocardial infarction, arrhythmia, pulmonary embolism, stroke, subarachnoid hemorrhage, significant hemorrhage, or any condition causing a return ED visit and hospitalization for a related event."
While the original paper identified a 96% sensitivity and 62% specificity for serious outcome (with negative predictive value 99.2% and positive predictive value 24.8%), validation studies have reported inconsistent results.
