Fifty patients with idiopathic mitral valve prolapse (MVP), diagnosed by M-mode ecocardiography and free of other cardiovascular disease, were studied by kinetocardiography (KCG), to detect the presence of left ventricular dyssynergy. Kinetocardiography showed paradoxical outward movements (POM) in 27 patients: these movements were pansystolic in 13 patients. The results were normal in 20 patients, unclear in 3 patients. POM were more frequently found in positions K4, K3 and K5. A comparison among results obtained with KCG and the other noninvasive techniques we used (ECG, ecocardiography and phonocardiography) showed that ectopic beats were more frequently associated with POM, which also were more frequent in patients with prolapse of both mitral leaflets and with pansistolic prolapse. Finally POM were recorded in patients with atypical or silent MVP. We conclude that KCG is an useful noninvasive technique to discover left ventricular dyssynergy in patients with MVP.
对50例经M型超声心动图诊断为特发性二尖瓣脱垂（MVP）且无其他心血管疾病的患者进行了心动力学描记法（KCG）研究，以检测左心室协同失调的存在。心动力学描记法显示27例患者存在矛盾外向运动（POM）：其中13例患者的这些运动为全收缩期。20例患者结果正常，3例结果不明确。POM在K4、K3和K5位置更常见。对KCG与我们使用的其他非侵入性技术（心电图、超声心动图和心音图）所获结果的比较表明，异位搏动与POM更常相关，POM在二尖瓣叶均脱垂和全收缩期脱垂的患者中也更常见。最后，在非典型或无症状MVP患者中记录到了POM。我们得出结论，KCG是发现MVP患者左心室协同失调的一种有用的非侵入性技术。
