目的探讨紧急床边心脏起搏联合美托洛尔治疗心室电风暴的应用价值。方法对3例电风暴患者采用普通电极导管行紧急床边心脏起搏,并联合应用美托洛尔治疗,其中2例为长QT间期诱发的恶性快速性室性心律失常。结果3例患者电风暴均得到控制,对有长QT的2例患者紧急床边心脏起搏效果显著。结论对于长QT导致电风暴者,紧急床边行快速心室起搏可终止电风暴。
Objective To investigate the clinical value of emergency bedside cardiac pacing combined with metoprolol in the treatment of ventricular electrical storm. Methods Three patients with electrical storm underwent emergency bedside cardiac pacing with a common lead and the combination of metoprolol therapy. Two of them were malignant rapid ventricular arrhythmias induced by long QT interval. Results The electrocution was controlled in all 3 patients, and the emergency bedside cardiac pacing effect was significant in 2 patients with long QT. Conclusion For long-QT lead to electric storms, emergency bedside rapid ventricular pacing can end the storm.
