The association of dysrhythmias with mitral valve prolapse in pediatric patients was investigated by graded treadmill exercise testing and 24-hour ambulatory ECG monitoring. Twenty-six unselected patients with a clinical diagnosis of mitral valve prolapse confirmed by echocardiography or angiocardiography or both were studied. On 24-hour ambulatory ECG monitoring, six patients (23%) had potentially serious ventricular dysrhythmias. Five of these patients also manifested ventricular dysrhythmias on treadmill exercise testing. Neither standard ECG abnormalities nor clinical symptoms correlated with detected dysrhythmias. This study shows that potentially serious ventricular arrhythmias are common in pediatric patients with mitral valve prolapse and that ambulatory ECG monitoring and treadmill exercise testing are useful for detecting dysrhythmias.
通过分级平板运动试验和24小时动态心电图监测，对小儿患者心律失常与二尖瓣脱垂的相关性进行了研究。研究了26例经超声心动图或心血管造影或两者确诊为二尖瓣脱垂的未经选择的患者。在24小时动态心电图监测中，6例患者（23%）有潜在严重室性心律失常。其中5例患者在平板运动试验中也表现出室性心律失常。标准心电图异常和临床症状均与检测到的心律失常无关。本研究表明，潜在严重室性心律失常在小儿二尖瓣脱垂患者中很常见，动态心电图监测和平板运动试验有助于检测心律失常。
