曾有几组报告,当停止地高辛维持治疗的(窦性节律)患者,常有无症状恶化,但非创伤性检查研究结果与此相矛盾。作者对一组窦性节律患者,进过M型超声心动图与收缩时间间期测定,观察地高辛长期维持治疗停止后的血液动力学变化,研究长期用药时能否保持变力性作用。 There have been several reports that asymptomatic exacerbation often eases in patients who have been treated with digoxin maintenance (sinus rhythm), but non-invasive examination findings contradict this. The authors of a group of patients with sinus rhythm, into the M-mode echocardiography and contraction time interval observed digoxin long-term maintenance treatment stopped after the hemodynamic changes to study the long-term medication can maintain the role of force.
