彩色多普勒在心脏起搏器综合征诊断中的应用价值

目的 :探讨运用彩色多普勒血流显像 (CDFI)并结合心电图 (ECG)诊断起搏器综合征 (PMS)的临床价值。方法 :对具有详实临床及ECG资料的心室按需 (VVI)起搏器安置患者 6 0例及对照组 4 8例进行CDEI检查 ,观察起搏组与对照组的三尖瓣返流 (TR)的发生率、返流程度 ,并分析二者之间的相关性。结果 :起搏组出现逆传P波 (即PMS阳性 )者 15例 ,CDFI检测出现TR者 2 0例 ,明显高于对照组 ,且PMS阳性者TR发生率明显高于PMS阴性者 ,表明安置VVI起搏器后出现逆传P波与TR的发生相关性良好。结论 :CDFI对PMS的诊断具有重要意义 ,尤其将ECG与CDFI结合应用有助于诊断率的提高。

APPLICATION OF COLOR DOPPLER FLOW IMAGE IN DIAGNOSING CARDIAC PACING MAKER SYNDROME

Objective:To Evaluate the clinic application of color Doppler flow imaging (CDFI) combined with electrocardiogram (ECG) in diagnosing PMS (pacing maker syndrome).Method:60 patients implanted cardiac pacing maker (VVI type) and 48 controls underwent CDFI and ECG.Results:In patient group,20 cases had tricuspid regurgitation (TR) in CDFI and 15 cases had reverse P wave which were indicated pacing maker syndrome (PMS) positive in ECG,and both were more than in the control group.Furthermore,TR was more often often found in those with PMS than those without PMS,which indicated that TR was well related to reverse P wave of implanting VVIpacing maker.Conclusion:CDFI combined with ECG was valuable for diagnosing PMS.
