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).
A cardiac arrest is also called a cardiopulmonary arrest or circulatory arrest and indicates a sudden stop in effective and normal blood circulation due to failure of the heart to pump blood. Cardiac arrest is different from myocardial infarction or heart attack but may be caused by a heart attack. When the blood flow to the heart is stopped due to narrow or obstructed coronary arteries, a heart attack occurs. This may lead to a cardiogenic shock and cardiac arrest.
