This chest tightness can change from day to day, and/or from moment to moment. All of the above combinations and variations are common. This type of chest tightness is commonly misconstrued as heart problems or the signs of a heart attack.
Cardiac arrest, also known as cardiopulmonary arrest or circulatory arrest, is a sudden stop in effective blood circulation due to the failure of the heart to contract effectively or at all. Medical personnel may refer to an unexpected cardiac arrest as a sudden cardiac arrest (SCA).
While a cardiac arrest may be caused by heart attack or heart failure, these are not the same. Prevention includes not smoking, physical activity, and maintaining a healthy weight. Treatment for cardiac arrest is immediate cardiopulmonary resuscitation (CPR) and, if a shockable rhythm is present, defibrillation.
