Definition
  1. Noun:
    • A sudden, often fatal medical emergency: "cardiac arrest" refers to the abrupt cessation of normal blood circulation due to the heart's failure to contract effectively. This results in the immediate absence of a pulse and loss of consciousness.
    • A state of absent systole: Specifically, it denotes the failure of the heart's ventricles to contract, which halts the heartbeat and prevents oxygen from reaching vital organs.
Usage Examples
  • Noun:
    • The patient was rushed to the hospital after suffering a cardiac arrest.
    • Immediate CPR is critical for survival following a cardiac arrest.
    • Cardiac arrest is different from a heart attack, though a heart attack can cause one.
Advanced Usage
  • "to go into cardiac arrest": to experience the sudden onset of cardiac arrest.
    • The athlete went into cardiac arrest during the marathon.
  • "to be in cardiac arrest": to be in the state of having no effective heartbeat.
    • The paramedics found the victim already in cardiac arrest.
Variants and Related Words
  • Arrest (n): In a medical context, can be used similarly (e.g., ). The term "cardiac" specifies the heart as the site of failure.
  • Asystole (n): A specific type of cardiac arrest characterized by a flatline on an ECG, indicating no ventricular electrical activity.
  • Sudden cardiac arrest (SCA) (n phrase): A common term emphasizing the unexpected nature of the event.
Synonyms
  • Asystole: (Technical) A state of no cardiac electrical activity, leading to no contraction.
  • Heart stoppage: (Informal) A non-technical term for the heart ceasing to beat.
Related Phrases
  • Cardiopulmonary resuscitation (CPR): The emergency procedure performed on someone in cardiac arrest.
  • Defibrillation: The treatment for certain types of cardiac arrest, like ventricular fibrillation.
Important Notes

Cardiac arrest is a clinical condition, not a disease itself. It is an event triggered by an underlying problem (e.g., ventricular fibrillation, severe arrhythmia, trauma). It leads rapidly to clinical death if not treated. It is distinct from a heart attack (myocardial infarction), which is a circulation problem often caused by a blockage, though a heart attack can be a cause of cardiac arrest.

Noun
  1. absence of systole; failure of the ventricles of the heart to contract (usually caused by ventricular fibrillation) with consequent absence of the heart beat leading to oxygen lack and eventually to death
