NCT04604639

Brief Summary

A cardiac arrest is often preceeded by a varying period of physiological deterioration which if acted upon may prevent the cardiac arrest. We aim to review patients presenting to the ambulance service with cardiac arrest so see if they had contacted the ambulance service in the preceeding 48 hrs to understand if warning symptoms were missed or not acted upon appropriately.
