Is heart attack always fatal?

Not at all. Only some unfortunate victims of heart attack die suddenly. Most of them do survive to reach the hospital and many of them lead normal lives after discharge from the hospital. It all depends on how severe the attack is and how promptly you get medical attention. Many sudden cardiac arrests due to heart attacks can be revived if cardiopulmonary resuscitation (CPR) is initiated promptly. An automatic external defibrillator can be helpful in this situation to shock the heart rhythm back to normal. All heart attacks need not cause a cardiac arrest, which is abrupt cessation of the pumping activity of the heart, usually due to an abnormal heart rhythm.
