What are common causes of cardiac arrest?

The correct answer highlights key factors that are widely recognized as common causes of cardiac arrest. Heart disease is one of the leading causes, often resulting from various conditions that affect the heart's structure and function, leading to compromised blood flow and oxygen delivery to the body's vital organs. Overdose from drugs, particularly opioids or stimulants, can disrupt the heart's rhythm and decrease its ability to pump effectively. Drowning leads to a lack of oxygen due to submersion in water, which can quickly result in cardiac arrest if not addressed immediately. Severe trauma, such as from accidents or violence, can cause injuries that disrupt normal heart function or significantly affect blood circulation, leading to cardiac arrest.

By understanding these causes, individuals are better equipped to recognize situations where cardiac arrest might occur and can be prepared to provide appropriate emergency response measures, such as CPR.
