本文报告141例预激综合征中并发快速性心律失常35例,占24.82％,其中室上速者21例(60％),室性早搏7例(20％),房颤3例(8.57％),房性与交界性早搏各2例(5.71％)。35例中有60％皆发生在无器质性心脏病患者中,发生原因主要为附加传导束的存在,使房、室之间产生折返激动所致。本组对频发性室上速一般方法治疗无效时,联合应用β受体阻滞剂,多巴胺和安定静脉滴注有较好疗效。对反复发作,临床表现严重的难治性病例,可在探明附加传导束的定位后考虑进行手术治疗。预激并发房颤时,有可能转化为室上速,因而及时应用药物或直流电转复是必要的。并发频发性早搏也可能演变为室上速或房颤,因而应及早进行处理。
This article reports 141 cases of pre-excitation syndrome in 27 patients with tachyarrhythmia, accounting for 24.82%, including 21 cases of supraventricular tachycardia (60%), ventricular premature beat in 7 cases (20%), atrial fibrillation in 3 cases (8.57% ), Atrial and borderline premature beats in 2 cases (5.71%). 60% of 35 cases occurred in patients with organic heart disease, the main reason for the existence of additional conductive bundles, so that room, resulting in reentry between the room. This group of general methods of treatment of frequent supraventricular tachycardia ineffective, the combination of β-blockers, dopamine and stable intravenous infusion has a good effect. Repeated attacks, severe clinical manifestations of refractory cases, can be found in the location of additional conductive bundles considered for surgical treatment. Pre-excitation concurrent atrial fibrillation, may be converted to supraventricular tachycardia, and therefore timely application of drugs or DC to restore is necessary. Concomitant premature beats may also evolve into supraventricular tachycardias or atrial fibrillation and should be treated as soon as possible.
