1例男性患者,埋藏式心脏转复除颤器(ICD)术后3个月,因“半天内ICD反复放电十余次”再次入院,程控ICD发现半天内放电34次,予提高室性心动过速(简称室速)/心室颤动(简称室颤)ICD低限识别频率,静脉补钾、泵入盐酸胺碘酮以及艾司洛尔等治疗无效,室速、室颤仍反复发作,部分需体外电除颤,遂静脉泵入右美托咪定,室速及室颤风暴获得明显控制,应用右美托咪定1h后再无室速/室颤发作。
One male patient underwent ICD re-entry within 3 months after ICD. The ICD was discharged 34 times during the first half of ICD. Tachycardia (referred ventricular tachycardia) / ventricular fibrillation (referred to as ventricular fibrillation) ICD low frequency identification, intravenous potassium, pump into the amiodarone hydrochloride and esmolol and other treatment is invalid, ventricular tachycardia, ventricular fibrillation is still recurrent , Part of the need for external defibrillation, then intravenous dexmedetomidine, ventricular tachycardia and ventricular fibrillation were significantly controlled by the application of dexmedetomidine 1h and then no VT / VF episodes.
