地高辛（Digoxin）是一種強心苷類藥物，具有正性肌力與負性心率（negative chronotropic）作用，能減慢房室結傳導。老年人因腎功能下降，藥物代謝較慢，極易發生洋地黃中毒。給藥前評估心尖脈（apical pulse）是臨床安全護理的黃金法則，若心率小於 60 次/分，必須暫停給藥並報告醫師，以避免嚴重的竇性心搏過緩（bradycardia）或心律不整。
Before administering digoxin, the nurse must assess the apical pulse for one full minute because the drug slows the heart rate and can cause bradycardia. If the pulse is less than 60 beats per minute, the dose should be withheld and the provider notified to prevent potential toxicity and serious arrhythmias.
