Sudden Cardiac Arrest (SCA) symptoms are immediate and dramatic and can include a loss of consciousness, sudden collapse, no breathing and no pulse. Sometimes other symptoms can occur before a sudden cardiac arrest. These symptoms may include fatigue, fainting, blackouts, dizziness, chest pain, shortness of breath, weakness, palpitations or vomiting. But often sudden cardiac arrest occurs with no warning.
