A heart attack occurs when blood flow to the heart muscle is blocked by an obstruction in an artery, whereas a cardiac arrest happens due to a sudden malfunction in the heart's electrical signals causing it to stop beating completely.
Common symptoms include chest pain or discomfort, pain radiating to the arms, back, neck, or jaw, shortness of breath, and dizziness. Main causes involve excessive smoking, an unhealthy diet, diabetes, high blood pressure, and being overweight.
If someone experiences a cardiac arrest, you must call for emergency medical help immediately and start CPR right away to increase their chances of survival until medical professionals arrive.
