Ivabradine
After randomization, the starting dose of ivabradine, 5mg, is given via the gastrointestinal tract every 12 hours. Heart rate control ranged from 70 to 94 bpm. Ivabradine was maintained until 96 hours after initiation of therapy. Beyond this period, the decision to continue ivabradine is left to the discretion of the treating intensivist. During the drug intervention period, heart rate is assessed before each dose. Ivabradine is tapered or discontinued if the heart rate is lower than the target rate; If the heart rate remains ≥95 bpm after 48 hours, the dose is increased to 7.5mg. If a heart rate of 95 or more bpm recurs after discontinuation during the intervention period, treatment with ivabradine can be resumed. Furthermore, Ivabradine is also discontinued at any time in the presence of severe liver impairment, malignant arrhythmia, cardiac conduction block, allergy, the need to take drugs with potentially harmful effects of ivabradine.
