As emergency physicians we want to stratify patients into risk
categories based on their short-term probability of death or adverse
event. This is in contrast to the internist who wants a more global
assessment of a patient’s health to determine long-term preventive
medications, such as statins. There are many tools we can use for this,
but one of the most powerful is the resting EKG.
1.Use of the PERC (Pulmonary Embolism Rule-out Criteria) rule can significantly decrease work-up for pulmonary embolism.
To apply this rule, the clinician must first use clinical gestalt to
classify the patient as low risk. The PERC rule, which consists of
eight clinical criteria including history, physical and vital signs,
can then be used. If both of these criteria are met, then there is less
than a 2 percent risk that this patient has a PE and no further work-up
