The association of dysrhythmias with mitral valve prolapse (MVP) in pediatric patients was examined by 48-hour ECG monitoring. Fifty unselected children with clinical diagnosis of MVP confirmed by echocardiography were studied. Eight (16%) patients manifested atrial dysrhythmias. Long runs of junctional rhythm with activity were recorded in one patient. Episodes of supraventricular tachycardia were recorded in 4 (8%) children. Seventeen (34%) patients had ventricular dysrhythmias. In 10 (20%) children, ventricular premature complexes (VPCs) were recorded. Four (8%) patients had frequent multifocal VPCs. Ventricular couplets were recorded several times in one patient (2%) and nonsustained ventricular tachycardia was recorded in two (4%) children. Clinical symptoms did not correlate with documented arrythmias. Although the prognostic implications of these findings are uncertain, this study demonstrated that potentially serious dysrhythmias are common in pediatric patients with MVP. It would appear that ambulatory ECG monitoring should be part of the complete evaluation of children with MVP.
通过48小时心电图监测，对小儿患者心律失常与二尖瓣脱垂（MVP）之间的关联进行了研究。研究对象为50名经超声心动图确诊为MVP的未经过筛选的儿童。8名（16%）患者出现房性心律失常。1名患者记录到伴有活动的长时间交界性心律。4名（8%）儿童记录到室上性心动过速发作。17名（34%）患者出现室性心律失常。10名（20%）儿童记录到室性早搏复合体（VPC）。4名（8%）患者出现频发多灶性VPC。1名患者（2%）多次记录到室性成对早搏，2名（4%）儿童记录到非持续性室性心动过速。临床症状与记录到的心律失常无相关性。尽管这些发现的预后意义尚不确定，但本研究表明，潜在的严重心律失常在患有MVP的小儿患者中很常见。动态心电图监测似乎应成为对患有MVP儿童进行全面评估的一部分。
