Cardiopulmonary resusitation (CPR):
CPR involves breathing for the victim and applying external chest compression to make the heart pump. In the case of an early heart attack, death can often be avoided if a bystander starts CPR promptly (within 5 minutes of the onset of ventricular fibrillation). When paramedics arrive, medications and/or electrical shock (cardioversion) to the heart can be administered to convert ventricular fibrillation to a normal heart rhythm. Therefore, prompt CPR and rapid paramedic respronse can improve the survival chances from a heart attack.
