cardiac death的意思|示意

Cardiac death is a form of death caused by loss of blood flow to the heart muscle. It is a medical term used to describe a sudden death due to cardiac arrest. Cardiac arrest occurs when the heart goes into a sustained rhythm (such as ventricular fibrillation, ventricular tachycardia, or asystole) and is not able to pump enough blood to the rest of the body. Without adequate blood flow, the person may experience no symptoms, or may experience sudden lightheadedness, chest pain, and/or shortness of breath. Cardiac death is a sudden death due to loss of blood flow, caused by cardiac arrest, and can occur within minutes.

Cardiac death is also known as cardiopulmonary death, sudden cardiac death (SCD), sudden cardiac arrest (SCA), cardiac arrest without warning, ventricular fibrillation, pulseless electrical activity (PEA) or sudden death due to heart disease. It is most commonly caused by coronary artery disease, cardiomyopathy, or ventricular fibrillation. Cardiac death can also be caused by trauma, electrocution, or overdose. Cardiac death is often not associated with any particular medical problem, but is due to the heart no longer being able to pump efficiently.

Cardiac death can be diagnosed in a number of different ways. A doctor can perform a physical examination and also look at the person’s medical records. Cardiac death can also be seen on an electrocardiogram (ECG), or an echocardiogram. ECGs and echocardiograms are common tests used to diagnose cardiac arrest or other heart problems.

Cardiac death is a diagnosis that is made after life has ended. It is important that a person’s doctor is familiar with their medical history and can interpret their ECG and echocardiograms accurately. In some cases, the cause of cardiac death may not be known. It is also important to know what specific treatments and measures a person should take to reduce their risk of sudden death due to heart disease.
