esmolol
Drugpatients in the esmolol group received continuous infusion of esmolol via a micro-pump through a catheter placed in the superior vena cava. The initial dose was 0.05 mg/kg/min and was adjusted based on heart rate (HR) (target HR: 70 bpm < HR < 100 bpm within 72 hours).
Control group also received natural saline via a micro pump, in the same way the esmolol group received esmolol.
