60例二尖瓣脱垂并心律失常的临床分析

A clinical analysis of 60 cases of mitral valve prolapse with arrhythmia

目的：研究二尖瓣脱垂（ Ｍ Ｖ Ｐ） 合并心律失常的临床特点。方法：对６０ 例 Ｍ Ｖ Ｐ 患者采用彩色多普勒超声显像仪检查确诊。２４ ｈ 动态心电图监测心律失常情况。结果：心律失常发生率８８４ ％ ，以室性早搏多见（６５ ％ ） ，其次室上性早搏（４０ ％ ） ，传导阻滞较少见（１１ ％ ） 。结论：大多数 Ｍ Ｖ Ｐ 合并心律失常不必治疗，多数预后较好。但如果症状明显，伴危险因素可给予β－ 阻滞剂。 Ｍ Ｖ Ｐ 并二尖瓣关闭不全或伴 Ｔ Ｉ Ａ 者可使用抗凝治疗。

Aim:To explore the clinical characteristics of MVP patient with arrhythmia. Methods: Further study of MVP patient with 24 hour dynamic electrocardiogram shown that most of MVP patients were accomanied with arrthythmia. Results: Incidence of arrthythmia is about 88 4% in which ventricular premature systole consisted of 65%. Next was supraventricular premature systole with incidence of 40%. Cardiac conductance blockage was least common with incidence of 11%. Conclusion: The prognosis is optimistic in most MVP patient with arrhythmia and therapeutic procedures are not necesary. However, in patients with apparent arrhythmia syndromes or with high risk factors, β-receptor blockers therapy is necessarty. Anticoagulant therapy is needed for MVP patients accommpanied with mitral valve incompetence or with TIA.
