Cardiac Arrest v/s Heart Attack
Although the terms are used interchangeably, cardiac arrest is different from heart attack. However, cardiac arrest can be caused by a heart attack. A heart attack happens if a narrowing or blockage in one of the coronary arteries stops blood flow to that part of the heart. You will remain conscious and experience symptoms like nausea and chest pain that may spread to your chest and arm. Cardiac arrest is caused by an electrical disturbance in the heart – it happens suddenly and you will likely lose consciousness.
