高血壓急症（Hypertensive emergency）的評估關鍵在於「終端器官受損」（End-organ damage）。手臂麻痺（Numbness）是神經學功能缺失的徵兆，提示可能正在發生腦血管意外（Stroke）。相較於噁心、視力模糊或心跳數值，神經症狀最具立即導致殘疾的風險，因此需優先處理。
In hypertensive emergency, the priority assessment is for end-organ damage. Unilateral arm numbness is a focal neurological deficit suggesting acute stroke and requires immediate intervention. Although blurred vision, nausea, and heart rate are part of the picture, neurological deficits carry the highest immediate risk of permanent disability.
