Background InformationBackground Information

40% of deaths under the age of 75yrs in 40% of deaths under the age of 75yrs in Europe are due to cardiovascular diseaseEurope are due to cardiovascular disease

One third of people who suffer a myocardial One third of people who suffer a myocardial infarction die before reaching hospitalinfarction die before reaching hospital

Most die within an hour of the onset of acute Most die within an hour of the onset of acute symptomssymptoms

The majority of these deaths the presenting The majority of these deaths the presenting rhythm is Ventricular Fibrillation or pulseless rhythm is Ventricular Fibrillation or pulseless Ventricular Tachycardia, (VF/ pulseless VT)Ventricular Tachycardia, (VF/ pulseless VT)


The only treatment for VF/ pulseless The only treatment for VF/ pulseless VT is attempted defibrillationVT is attempted defibrillation

With each minute’s delay the chance With each minute’s delay the chance of a successful outcome fall by 7-of a successful outcome fall by 7-10%10%

Once in hospital the incidence of VF Once in hospital the incidence of VF after Myocardial Infraction is after Myocardial Infraction is approximately 5%approximately 5%

Most likely presentation of in hospital Most likely presentation of in hospital cardiac arrest is asystole or pulseless cardiac arrest is asystole or pulseless electrical activity (PEA).electrical activity (PEA).
