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 sudden cardiac arrest can also occur with no warning.

Consult your doctor with any questions regarding any symptoms you may be experiencing and your medical condition.
