Epidemiology of Sudden Cardiac Arrest

In the past 20 years, there have been significant changes in the way myocardial infarction is managed, particularly with respect to revascularisation. As myocardial infarction is one of the major risk features for sudden death, these changes may have important implications for underlying epidemiology of sudden cardic death and the declining frequency of ventricular tachyarrhythmia as the cause. The study aims: 1. to characterise the condition of patients presenting to Wellington Free Ambulance between 1/1/2008 and 31/12/2015 (5 year period) prior to their sudden cardiac arrest. 2. to compare patient characteristics with those described in earlier literature to determine whether changes have occured in the epidemiology of sudden cardiac death over the last 20 years. 3. to compare the pre-existing condition of patients presenting with sudden VT/VF arrest and those presenting in other rhythms (PEA/asystole).
