Examples
- The patient's condition deteriorated rapidly and he went into cardiac arrest, requiring immediate medical intervention.
- Cardiac arrest can occur suddenly and without warning, making it a potentially life-threatening medical emergency.
- The athlete's collapse on the field was initially mistaken for exhaustion, but it turned out to be a cardiac arrest caused by underlying heart problems.
- In cardiac arrest, the heart stops pumping blood and oxygen to the rest of the body, leading to brain damage or even death if not treated promptly.
- Prompt CPR and defibrillation are crucial in cases of cardiac arrest, as they can help restore a normal heartbeat and prevent long-term damage.
