Nontraumatic Cardiac Arrest
To determine the incidence and significance of upper body cyanosis in adult non-traumatic cardiac arrest 108/3526 patients had mention of nipple line cyanosis on EMS patient record 38 had autopsy data available 6/38 had haemopericardium compared to none in control group Small numbers – 38/108 had autopsy data

Retrospective patient record review

10 other causes found in remaining 32 patients albeit no significant differences with control group
