致心律失常性右室心肌病患者Epsilon波的检出率

Objective To investigate the prevalence of Epsilon wave in patients with arrhythmogenic right ventrieular cardiomyopathy (ARVC). Methods The Epsilon wave was detected in 32 patients [24 men, mean age (42.3±13.3) years] with ARVC using three different electrocardiography (ECG) recording methods: standard twelve leads ECG (S-ECG), right precordial leads ECG (R-ECG) and Fontaine bipolar precordiai leads ECG (F-ECG). The Epsilon wave was defined as wiggle, small spike wave and smooth potential between the end of the QRS complex and the beginning of the ST segment. Results Epsilon wave was detected in 37.5%, 37.5% and 50.0% patients with ARVC by S-ECG, R-ECG and F-ECG respectively. The detection rates derived from the three recording methods were similar(P ＞ 0.05). The Epsilon wave was only detectable by S-ECG in one case, by R-ECG in three cases, and by F-ECG in five cases. The detection rate of Epsilon wave was 50.0% by combined use of S-ECG and R-ECG (SR-ECG), 56.3% by combined use of S-ECG and F-ECG (SF-ECG), and 65.6% by combined use of the three recording methods (SRF-ECG). The detection rate was significantly higher by SF-ECG (56.3%) and SRF-ECG (65.6%) than by S-ECG alone (37.5%, all P ＜0.05). Most Epsilon waves detected by the S-ECG, R-ECG and F-ECG were small spiked waves. Conclusion Combined use of S-ECG, F-ECG and R-ECG could increase the detection rate of Epsilon wave in patients with ARVC.

远端血管保护装置GuardWire在急性心肌梗死急诊介入治疗中的应用

目的　评价GuardWire在急性心肌梗死 (AMI)急诊介入治疗时应用的价值。方法　连续观察 4 8例AMI急诊介入治疗并应用了GuardWire的患者 ,记录术中心电图变化及血流情况等 ,分析该装置的操作、造影和手术成功率 ,以及住院期间和术后 30d内的心血管事件发生率。结果　操作成功率、造影成功率和手术成功率均为 10 0 %。远端球囊阻塞时间平均 (8 1± 6 8)min ,所有患者均能良好耐受。 93 8%的患者吸引出肉眼可见的血栓 /斑块碎片 ,术中未出现因远端血管阻塞而引起的血液动力学或心电图、症状变化 ,未出现远端血管栓塞或无血流现象。住院期间和术后 30d内的心血管事件发生率均为 0。结论　该装置容易操作 ,可安全地应用于冠状动脉系统 ,有效防止AMI急诊介入治疗中可能出现的远端血管栓塞。     

心房颤动山羊模型转复窦性心律后血液和心房肌组织中醛固酮水平的变化

目的:研究心房颤动(Af)山羊模型恢复窦性心律后血液和心房肌组织中醛固酮水平的变化.方法:18只成年山羊,体重相仿,雌雄不限,随机分成3组,其中窦性心律组(A组)6只,Af模型组(B组)6只,Af模型复律组(C组)6只,3组均行开胸手术,左心耳缝入起搏电极,A组不起搏,B、C组持续快速心房起搏3个月形成Af模型,3个月后处死A、B组山羊,取左、右心房肌组织冻存,C组停止起搏,予心律平静脉注射或加用直流电复律,维持窦性心律3个月,之后处死C组山羊,取左、右心房肌组织冻存,用ELISA法测定各组心肌标本中醛固酮水平.C组在Af前、Af后3个月、复律后2周、1个月、2个月、3个月时各留取血清标本,用放射免疫法测定血清醛固酮水平.结果:C组心肌组织醛固酮水平低于B组(P＜0.01),与A组比较则差异无统计学意义(P＞0.05),左、右心房肌组织醛固酮水平差异无统计学意义(P＞0.05);Af复律后2周、1个月、2个月、3个月血清醛固酮水平呈递减变化.结论:Af恢复窦性心律后血液和心房肌组织中醛固酮水平下降.     

宫内感染与早产儿支气管肺发育不良

肺脏是宫内感染后容易受累的重要器官之一,可以阻碍肺发育,引起肺损伤,与支气管肺发育不良(bronchopulmonary dysplasia,BPD)的发生密切相关。BPD是常见于早产儿的一种慢性肺疾病,随着早产儿生存率不断的提高,BPD的发生率也显著上升,了解宫内感染与早产儿支气管肺发育不良结局之间的关联,对减少新生儿肺不良结局的发生率,对优生优育有着重要意义。
