摘 要:目的:总结老年继发孔型房间隔缺损(ASD)患者封堵术前后心电图表现和心房颤动(房颤)对血流动力学及心腔内径的影响。方法选择2002年6月至2012年6月沈阳军区总医院收治的应用ASO经导管成功堵闭ASD的老年患者114例,记录封堵前及封堵后一周内心电图指标的变化:QRS电轴、V1(V3R)导联右室肥厚QRS图型、V5~6导联T波改变和主要心律失常。结果(1)术前:QRS电轴右偏27例(23.7%),不偏75例(65.8%),左偏12例(10.5%);V1(V3R)呈rsR'型82例(71.9%),CRBBB型11例(9.6%),Rs型2例(1.8%),rS型19例(16.7%);V5~6导联T波倒置9例(7.9%);房颤30例(26.3%),室性早搏3例(2.6%),病态窦房结综合征2例(1.8%)。(2)术后:QRS电轴7例(25.9%)右偏恢复正常,3例(2.6%)右室肥厚消退,3例(33.3%)V5~6导联T波倒置者转正常,术后虽有2例房颤患者转成窦性心律,但新发生房颤4例。(3)血流动力学检测:114例平均肺动脉压(mPAP)为(24.6±7.4)mmHg,房颤组为(28.2±1.2)mmHg,非房颤组为(24.2±0.8)mmHg,两者之间差异无统计学意义(P〉0.05)。(4)超声心动图检测结果显示左心房内径房颤组较非房颤组明显增大(P〈0.01)。结论与其他年龄组比较,老年患者术前QRS电轴不偏、左偏、V1(V3R)导联呈CRBBB型和房颤常见;术后QRS电轴右偏转正常(25.9%)和缺血性T波改善(33.3%)较明显,但右室肥厚消退和心房颤动下降率不明显。房颤患者左房内径增大明显,与mPAP无关。Objective To summarize the ECG characteristics and atrial fibrillation influences on hemodynamics and cardiac cavity diameter in elderly patients with atrial septal defect before and after occlusion. Methods We record the ECG parameter variations of 114 elderly patients with ASD per-operation and a week after post-operation. Results (1)Peroperative:QRS right axis deviation in 27 cases (23.7%), 75 cases (65.8%) without deviation and left axis deviation in 12 cases (10.5%); V1(V3R) in 82 cases of rsR type (71.9) , CRBBB in 11 cases (9.6%), 2 cases of Rs type (1.8%), 19 cases of rS type (16.7%);9 cases of inversion of TV5-6 (7.9%);30 cases of atrial fibrillation (26.3%), 3 cases of ventricular premature beat (2.6%) and 2 cases of sick sinus syndrome (1.85%). (2)Postoperation:7 cases of QRS right axis deviation turned to normal (25.9%), 3 cases of right ventricular hypertrophy (2.6%) vanished, 3 cases of TV5-6 inversion turned to normal(33.3%). Although there were 2 cases of Af converted to sinus rhythm, 4 new cases of Af occured. (3)Hemodynamics:The mPAP of 114 cases was 10-46(24.6±7.4)mmHg, Af group 13-46(28.2±1.2)mmHg, non-Af group 13-45(24.2±0.8)mmHg , there was no significance difference between them(P〉0.05). (4)Echocardiography showed that the left atrial diameter Af group were significantly increased compared with non-Af (P〈0.01). Conclusion It suggests that ECG QRS axis without deviation, left axis deviation, V1 (V3R)-CRBBB and atrial fibrillation are more common in elderly patients than in other age groups before occlusion . After occlusion, QRS right axis deflection turns to normal (25%) ,what is more, ischemic T wave comes better (33.3%) than before obviously, but right ventricular hypertrophy regression and the declining rate of atrial fibrillation is not significant. It seems to have a high incidence of left atrial enlargement in patients with ASD and Af (P〈0.01), and
