How is cardiac arrest defined?

• A. The heart is beating slowly
• B. The heart has stopped beating
• C. The heart is beating irregularly
• D. The heart is racing

Answer: (B)

Cardiac arrest is defined as the state in which the heart has stopped beating altogether. This condition is critical and requires immediate medical intervention. In cardiac arrest, there is no effective circulation or blood flow to the body, which leads to the cessation of essential functions. Oxygen and nutrients are no longer delivered to the organs, which can result in irreversible damage if not addressed quickly. The absence of a heartbeat signifies that the heart is not functioning in its capacity to pump blood, leading to unconsciousness and the potential for death if proper resuscitation efforts are not initiated.
