Definition:
"Cardiac arrest" is a medical term that describes a situation when the heart stops beating. This means that the heart is not pumping blood to the rest of the body, which can lead to a lack of oxygen and can be life-threatening.
In medical contexts, "cardiac arrest" may be discussed alongside terms like "ventricular fibrillation," which is one of the common causes of cardiac arrest. Healthcare professionals may also talk about "CPR" (cardiopulmonary resuscitation), which is a technique used to help someone who has had a cardiac arrest.
While "cardiac arrest" specifically refers to the heart stopping, the word "arrest" can have other meanings, such as: - Arrest (verb): To stop someone for a crime. - Example: "The police arrested the thief."
There aren't specific idioms or phrasal verbs that directly relate to "cardiac arrest," but the phrase can be used in expressions about emergencies, such as: - "Call for help" – to request emergency assistance. - "Jump into action" – to start doing something quickly in response to an emergency.
In summary, "cardiac arrest" is a serious medical condition where the heart stops beating. It is crucial to act quickly in such situations, as it can lead to death if not treated immediately.
