What are the symptoms of sudden cardiac arrest?

If you find yourself suddenly finding it difficult to breathe, feeling faint, and/or having palpitations, it is important to seek medical attention as soon as possible. If you experience any of these symptoms, even if they only last for a short period of time, you should seek emergency care.

The Signs of Sudden Cardiac Arrest

When someone has a heart attack, the heart muscles become weakened and can no longer pump blood. This can lead to a heart attack death in less than five minutes if not treated. However, there are other causes of sudden cardiac arrest that are just as life-threatening.

Signs of sudden cardiac arrest include: chest pain, shortness of breath, sweating, nausea, and lightheadedness. If you experience any of these signs, it is important to call 911 right away. If you see someone who is having a cardiac arrest, try to resuscitate them using CPR (cardiopulmonary resuscitation).
