二尖瓣脱垂(MKP)合并心律失常,过去颇多报道,然而在某些观点方面,迄今仍有出入。本文复习了近年来有关资料,并阐述于下。 MKP合并心律失常的种类和发病率:50％以上的MKP常合并心律失常;最常见为室性早搏(VES),其次为室上性早搏,较少见的为室上性心动过速、室性心动过速,至于窦性心动过缓则极为罕见。在Baedecker分析的160例MKP患者中,心律失常可达74％;其中室性心律失常占65％,VES分级 Mitral valve prolapse (MKP) with arrhythmia, a lot of reports in the past, however, in some aspects, so far there are still discrepancies. This article reviewed the relevant information in recent years, and described in the next. The type and incidence of arrhythmia associated with MKP: more than 50% of MKP often associated with arrhythmia; the most common is ventricular premature beats (VES), followed by supraventricular premature beats, the less common are supraventricular tachycardia, Tachycardia, as sinus bradycardia is extremely rare. In the 160 patients with MKP analyzed by Baedecker, the arrhythmia was 74%, of which 65% were ventricular arrhythmias and VES was classified
