摘要:
目的 测量激光心肌血运重建术(TMR)后的QT离散度(QTd)和心率校正QT离散度(QTcd),并探讨其临床意义。方法 随访记录单纯行TMR的14例患者术前1 d、术后1周,1,3,6月及1年的心电图,同时观察症状缓解和心功能改善状况。结果 患者术后QTd、QTcd明显下降,3月时基本恢复正常水平(44.4±20.5 ms;47.0±19.1 ms),6月后QTd,QTcd似有轻度升高,但统计学检测尚无明显差异。心绞痛症状明显缓解,心功能明显改善。结论 TMR术后QTd,QTcd明显减少与症状缓解和心功能改善相一致,可将QTd,QTcd作为TMR术后疗效观察的一项指标。
Abstract:
To measure the QT dispersion degree (QTd) before and after transmyocardial revascularization by laser (TMR) and assess its clinical value.Methods:We recorded the electrocardiogram of 14 patients with coronary heart disease before and after operation and analysed its QTd,QTcd.Results:The QTd and QTcd decrease progressively almost normal in 3 months (44.4±20.5 ms;47.0±19.1 ms),increase slightly in 6 months (51.4±18.5 ms;56.6±14.5 ms) and stable in 1 year (51.4±18.5;56.6±16.5 ms).Conclusion:QTd and QTcd are reliable and convenient indices in assessing the curative effect of TMR.
