- AHeart rate 52 beats/min and anorexia✓ 正解心率52次/分及食慾不振
- BPeripheral edema in the lower extremities下肢周邊水腫

Digoxin 中毒的早期徵象包含腸胃道症狀（食慾不振、噁心、嘔吐）以及心律不整（常見為心搏過緩，HR < 60）。視覺異常（黃綠視）也是典型症狀。血壓和呼吸頻率並非 digoxin 中毒的直接特異性指標。
Digoxin toxicity commonly presents with gastrointestinal symptoms, such as anorexia, nausea, and vomiting, along with cardiac manifestations like bradycardia (heart rate < 60 beats/min). Visual disturbances, including yellow-green halos, are also classic signs. Monitoring for these specific indicators allows for early detection and intervention to prevent serious adverse effects.
✦ 台美臨床差異
在美國 NCLEX 考試中，Digoxin 中毒與電解質（特別是低血鉀）的關係是常考重點；台灣教學亦強調心跳低於 60 應暫停給藥。
