简介:摘要:本研究公开了一种可医用的骨折康复训练系统,涉及医疗技术领域。利用脑机接口及虚拟现实技术(VR)通过监测、识别脑电信号和发挥VR的多源信息融合的交互式的三维动态视景和实体行为的系统仿真使用户沉浸到该环境中的作用,使人们的大脑主动的将意图和想法转换成对多自由度下肢机械外骨骼的控制指令,从而使大脑的电信号通过神经传导反复刺激下肢术后接好的神经并结合专业的康复训练动作精准的把握适合人体下肢骨骼恢复的最佳活动度数,达到全智能化高效精确地辅助骨折引起的神经性损伤患者进行手术后康复训练。
简介: 【摘要】 目的 分析常规心电图与动态心电图诊断冠心病伴心律失常患者的临床价值。方法 60例冠心病伴心律失常患者, 先进行常规心电图检查, 再进行动态心电图检查。观察比较患者常规心电图、动态心电图诊断检出率, 并统计异常心电监测检出情况。结果 60例患者常规心电图检出冠心病伴心律失常 34例, 检出率为 56.67%;动态心电图检出冠心病伴心律失常 55例, 检出率为 91.67%。动态心电图检出率显著高于常规心电图, 差异具有统计学意义( P<0.05)。动态心电图检查室性早搏, 房性早搏, 室性早搏成对, 房室传导阻滞, 短阵室上速, 室性早搏二、三联律及房性早搏二、三联律检出率均显著高于常规心电图, 差异具有统计学意义( P<0.05)。结论 动态心电图对冠心病伴心律失常及相关异常心电的诊断效果较好, 显著优于常规心电图, 可为该疾病诊断提供重要参考依据。 【关键词】 常规心电图 ;动态心电图 ;冠心病 ;心律失常 ;诊断价值 ;异常心电 [Abstract] Objective To analyze the clinical value of routine electrocardiogram and dynamic electrocardiogram in the diagnosis of coronary heart disease with arrhythmia. Methods 60 patients with coronary heart disease and arrhythmia were examined by routine electrocardiogram and then by dynamic electrocardiogram. The detection rate of routine ECG and Holter was observed and compared, and the detection rate of abnormal ECG was counted. Results 34 cases of coronary heart disease with arrhythmia were detected by routine ECG, the detection rate was 56.67%; 55 cases of coronary heart disease with arrhythmia were detected by dynamic electrocardiogram, the detection rate was 91.67%. The detection rate of Holter was significantly higher than that of routine ECG (P < 0.05). The detection rates of ventricular premature beat, atrial premature beat, pairs of ventricular premature beats, atrioventricular block, short supraventricular tachycardia, two and three laws of ventricular premature beat and atrial premature beat were significantly higher than those of routine electrocardiogram (P < 0.05). Conclusion dynamic electrocardiogram has a good effect in the diagnosis of coronary heart disease with arrhythmia and related abnormal ECG, which is significantly better than conventional ECG, and can provide important reference for the diagnosis of the disease.
简介:【摘要】目的 观察电子计算机断层扫描(CT)动态灌注成像技术测定肝脏血流量中的应用价值。方法 回顾性分析该院2022.04-2023.04的间24例肝硬化患者,作为实验组,再选取同期入院体检的健康者24例,作为对照组,2组同时实施 CT 动态灌注成像检验,对比组间肝动脉灌注量(HAP)、门静脉灌注量(PVP)、总肝血流量(tHBF)、肝动脉灌注指数(HAPI)、平均通过时间(MTT)、对比剂分布容积(Vd)的差异。结果 对比对照组,实验组的肝硬化患者的HAP、PVP和THBF都降低,MTT存在延长,组间对比差异有统计学意义(P<0.05),但2组HPI和DV对比,差异无统计学意义(P>0.05)。结论 利用 CT 灌注成像测定肝脏血流量具有无创、安全等优势,值得运用。
