Clinical implication of mechanical alternans is yet unclear. It may suggest the risk for sudden death in patients with chronic heart failure. Two cases with dilated cardiomyopathy showed mechanical alternans during diagnostic cardiac catheterization. They suddenly died due to ventricular fibrillation before the induction of beta-blocker therapy. Patients with mechanical alternans should be treated under intense monitoring until the induction of beta-blocker therapy.
机械性交替脉的临床意义尚不清楚。它可能提示慢性心力衰竭患者猝死的风险。两例扩张型心肌病患者在诊断性心导管检查期间出现了机械性交替脉。他们在开始β受体阻滞剂治疗前因室颤突然死亡。出现机械性交替脉的患者应在严密监测下接受治疗，直至开始β受体阻滞剂治疗。
