— Explanation · 中文詳解 —
Metoprolol 為 beta-受體阻斷劑，具有減慢心率的作用。若心率 <60 下/分，通常依醫囑或慣例暫停給藥，以防誘發嚴重心動過緩。其他藥物（Lisinopril、Aspirin、Atorvastatin）對心率無直接減慢效應。
Metoprolol is a beta-blocker that slows heart rate. When the heart rate is <60 bpm, the medication is typically held according to provider orders or standing protocol to prevent severe bradycardia. The other medications (lisinopril, aspirin, atorvastatin) do not have a direct heart-rate-lowering effect.
