Which condition requires immediate medical attention to potentially prevent cardiac arrest?

Eclampsia requires immediate medical attention because it is a serious and potentially life-threatening condition that can occur during pregnancy or postpartum. It is characterized by the onset of seizures and is often preceded by severe preeclampsia, which involves elevated blood pressure and potential organ dysfunction. The seizures associated with eclampsia can lead to various complications, including cerebral edema, brain damage, and, ultimately, cardiac arrest if not managed promptly.

In contrast, while hypertension, obstructive sleep apnea, and hyperlipidemia are important medical conditions, they do not present the same immediate acute risk of progression to cardiac arrest. Hypertension, for example, can lead to long-term cardiovascular issues but typically does not cause acute events like seizures. Obstructive sleep apnea can lead to other complications over time, but it doesn’t usually escalate to an immediate crisis requiring urgent intervention. Hyperlipidemia also poses long-term cardiovascular risks but is generally manageable with lifestyle changes and medication and does not result in immediate medical emergencies like eclampsia does.
