— Explanation · 中文詳解 —
地高辛中毒的典型臨床徵兆包括視覺異常（如看到物體周圍有黃綠色光暈）、噁心嘔吐、心律不整及意識混亂。其他選項如高血壓、增加食慾均非典型中毒表現。看到光暈是此藥中毒的特徵性症狀（Visual disturbances）。
Classic clinical signs of digoxin toxicity include visual disturbances (such as yellow-green halos around objects), nausea and vomiting, dysrhythmias, and confusion. Other options such as hypertension or increased appetite are not typical signs of toxicity. Seeing halos is the characteristic visual disturbance of digoxin toxicity.
✦ 台美臨床差異
台灣針對地高辛中毒的衛教常強調「嘔吐與心跳過慢」，對於視覺光暈的教導亦為重點，兩地並無顯著差異。
