 | | VF is responsible for 75% to 85% of sudden deaths in persons with heart problems. |
 | | Whether the person having VF suddenly falls unconscious at home or in the street, or the person is in the hospital (and VF is diagnosed from a cardiac monitoring station), it is indispensable to initiate immediate cardiopulmonary resuscitation (CPR). |
 | | The most common complication of VF is sudden death (death within 1 hour of the onset of symptoms), followed by death in the hospital (among people who were transferred to a hospital after being rescued at home, in the street, or in the workplace). |
