Bradycardia, hypotension, and severe liver damage due to amiodarone

A 69-year-old women received an IV push of amiodarone 150 mg for arrhythmia,paroxysmal supraventricular tachycardia,and a heart rate of 166 beats/min. Thirty minutes later,the patient developed sinus bradycardia and hypotension. Her heart rate was 35 beats/min and blood pressure was 81/50 mm Hg. She was undergone temporary pacemaker. Meanwhile fluid supplementation and an IV dopamine were given. One hour later,her symptoms relieved. She was treated with an IV infusion of amiodarone 300 mg diluted in 5% glucose 50 ml via pump at a rate of 0.6 mg/min for intermittent episodes of tachycardia. The next day,her laboratory tests revealed the following values：ALT 1 770 U/L,AST 1 360 U/L,TBil 130.20 μmol/L,DBil 98.40 μmol/L; PT 17.3 s,INR 1.45.
