EpistemisCanadian Syncope Risk Score (risk after syncope)
Predicts the serious adverse event at 30 days in the patient who comes to the emergency room due to syncope and has already been evaluated. It is the scale that justifies the discharge of vasovagal syncope and detects the one that hides an arrhythmia.

This page explains the score but does not run it. In Epistemis, the calculator validates units, flags values outside physiological ranges, and provides the interpretation that a number alone cannot convey.
Epistemis is educational review material. It is not a medical device, does not diagnose or prescribe treatment, and does not replace formal medical training, current clinical guidelines, or professional clinical judgment.
