简介：所谓边缘性Q波是措不能完全符合异常Q波标准的Q波。其分为二种类型。1.接近异常Q波的边缘性Q波,此种Q波表现为Q波粗钝错折,时限≥0.04秒,此种Q波按异常Q波对待;若同时同导联S—T段抬高、T波倒置,则肯定为异常Q波。

简介：常规12导联心电图诊断右室梗死的病例比较少见,诊断心房梗死的就更少见,本院收治的1例晚期肺癌,其体表心电图呈典型的心房梗死合并右室梗死,心房梗死的表现形式不是常见的P-Ta改变,而是出现罕见的房性“Q”波,报道如下.

简介：目前医学界越来越重视Q—T间期改变，Q—T间期延长和Q—T间期离散度的变化，易致心律失常乃至心脏猝死。对其病因、发生机制、临床意义及治疗有了突破性进展。

简介：目的：通过分析非心肌梗死患者体表心电图出现异常Q波及其对应的相关疾病，探讨非梗死性异常Q波的产生机制及其临床意义。方法：260例心电图均存在异常Q波的患者，在排除心肌梗死诊断后，分析与其基础疾病的关系，并分析异常Q波在不同导联上的分布情况，结果：一些疾病如心肌病，肺心病，某些心律失常合并存在的非梗死性异常Q波多呈定位分布，且以单一部位多见，单一部位出现异常Q波者又以Ⅱ、Ⅲ、avF及V1－V3导联最常见，结论：除心肌梗死外尚有很多疾患可出现异常Q波为特征的心电图表现，临床上勿将此类患者误诊为心肌梗死。

简介：目的本实验采用高效液相色谱法测定两种辅酶Q10片的血药浓度，进行人体生物利用度比较研究。方法10位健康男性受试者按交叉试验连续多次口服两种辅酶Q10片，由于体内存在一定量的辅酶Q10，一次给药后血中辅酶Q10的增加量有限。为了能比较准确地测定口服辅酶Q10后体内浓度的变化，根据文献报导，本研究采用低剂量给药7d后，待体内辅酶Q10浓度较恒定后再给以较大剂量的交叉试验方案。第一组5人d1-d7每天服药3次。每次20mg，每天共60mg，第8d早晨服药60mg；第二组5人按同样方法服用同剂量的对照品。2周后进行第二次试验，交叉一次服用同剂量的对照品和试验品。d8早晨于服药前、服药后1、2、3、4、6、8、12h各采静脉测定血清中辅酶Q10浓度。结果试验的主要药代动力学参数分别为Tpeak=(4.00±1.25)h;Cmax=(0.66±0.17)μg·ml^-1；AUC=（5.91±1.78)μg·h·ml^-1。对照品的参数分别Tpeak=（4.60±1.58)h;Cmax=(0.70±0.20)μg·ml-1；AUC=（6.30±2.09)μg·h^-1·m^-1。试验表明两制剂的AUC、Cmax及Tpeak均无显著差异。结论辅酶Q10试验片剂对照片剂的相对生物利用度为93.9%,经等效性检验分析表明这两种制剂具有生物等效性。

简介：目的:探讨Q开关Nd:YAG激光后囊膜切开术治疗后囊膜混浊的疗效及安全性.方法:回顾性分析行Q开关Nd:YAG激光后囊膜切开术后囊膜混浊患者165例(193眼),记录手术前后视力、眼压及并发症,并进行统计学分析.结果:①后囊膜一次性切开成功率为100%,所用激光脉冲数平均24±21.7次,激光总能量4～451mJ;②91.2%(176眼)视力较术前提高;③59.6%(115眼)出现一过性眼压升高;手术前后眼压变化与是否植入人工晶状体、所用激光脉冲数以及白内障手术与后囊膜切开术间隔时间有关;④19.3%(32眼)出现人工晶状体损伤.结论:Q开关Nd:YAG激光后囊膜切开术治疗后囊膜混浊安全、有效,但应严格掌握适应证,并合理选择激光参数.
