A heart attack is caused when the blood supply to the heart is blocked, but the heart keeps beating. The patient is conscious, breathing and can be talking, but has symptoms such as pains in one or both arms and chest. There are other possible symptoms such as cold sweats, nausea and feeling lightheaded.
Sudden Cardiac Arrest (SCA)
An SCA occurs when the heart’s electrical system goes haywire, causing an arrhythmia. There are many types of arrhythmias. The arrhythmia that causes SCA is one where the heart stops pumping blood to the brain and other vital organs. An SCA can happen to anyone regardless of age, fitness, or diet.
