右室双部位双心室同步起搏治疗心力衰竭一例

心房颤动伴Ⅲ度房室传导阻滞患者，接受VVI型人工心脏起搏器置入术后出现心力衰竭。在保留原起搏器及导线的情况下，新置入2根电极导线分别至右事，及左室侧后静脉，与DDD起搏器心室及心房接口连接，行右室双部位双室同步起搏，临床疗效可。

射频消融术中颈内静脉穿刺的评价

患者女 ,38岁。因“阵发性心悸 5年”收入院。发作心电图为“室上性心动过速”,入院拟行射频消融术治疗。既往无高血压、糖尿病及其它心脏病史。查体 :BP130 / 75 m m Hg,术前常规检查血肝肾功能、全胸片、心脏扇超均在正常范围。术中常规准备给予右侧颈内静脉穿刺 ,嘱患者左偏头部 ,在触及颈动脉后在其外侧准备行利多卡因局麻 ,随即患者双眼上翻 ,四肢强直 ,口吐白沫 ,心电监护示一直线。立即给予心肺复苏术 ,约 4分钟后神志恢复 ,安返病房。追问病史患者既往有晕厥病史 ,且可以自行缓解。次日给予脑电图和头颅 CT检查 ,均未发现异常。考…     

食管造影及温度监测指导环肺静脉消融治疗心房颤动

Objective Because of the severe consequences of an atrial esophageal fistula,it is vital to avoid this complication. The most safe way is to avoid ablating the segment of esophagus behind left atrium (LA). What we do is to image the relationship of esophagus to posterior LA wall and real-time esophageal tem-perature monitoring to ablate the posterior LA wall. Methods Sixty-four patients with paroxysmal atrial fibrilla-tion (PAF) were enrolled to pulmonary veins (PV) isolation. Swallowing a radiocontrast agent at the same time when imaging of LA to observe the relationship of esophagus to posterior LA wall and according to the different relationship between the segment of esophagus behind LA and PV, the esophagus were divided into type Ⅰ , type Ⅱ and type Ⅲ. A esophageal temperature probe was inserted and advanced into the esophagus directly posterior to the LA. Three steps ablation strategy and real-time esophageal temperature monitoring were applied to guide the PV isolation. The procedure was interrupted when the esophageal temperature was 39℃ until] the tempera-ture renormalized and ended when PV were isolated. Results There were 48 type ⅠI , 11 type Ⅱ and 5 type Ⅲ esophagus in the 64 patients. After three steps ablation,all PV isolations were completed. Only 18.8% of the patients needed to ablate the posterior LA close to the esophagus. Conclusion Only one PV ostiolum close to the posterior LA wall in most PAF patients and many of them can achieve complete PV isolation without ablating the posterior LA close to esophagus which could minimize the risk of esophageal injury dramatically.     

急性心肌梗死患者直接PCI后的心电图ST段回落分析

目的:联合应用TIMI心肌灌注分级(TMP)、心电图ST段变化(sumSTR)方法评价急性心肌梗死(AMI)急诊经皮冠状动脉介入治疗(PCI)后心肌灌注程度。方法:连续入选57例AMI患者,按梗死部位分为前壁组和下壁组,于6h～12h内行直接PCI,并于手术前后分别记录ST段变化和TMP变化,从而评价心肌灌注程度。结果:对比57例AMI患者PCI前后记录显示,术后ST段明显回落TMP数值上升。结论:PCI对AMI患者疗效显著。     

慢旁道负责的室上速的电生理特征

目的：探求为‘慢旁道(slow APs)’所致‘疑难室上速(SVT)’的正确诊断寻找模块化的诊断方法。方法：使用心内电生理检查明确诊断后，行射频消融(RFCA)治疗。结果：1、均诱发窄ORS心动过速；2、3例“慢旁道”位置位于左侧，1例位于后间隔(冠状窦口内)3、肢体导联与旁道位置有一定的关联。结论：明确“慢旁道”的电生理特征，建立规范化的心内电生理检查程序是有必要的。     

浅谈理解和分析心电图的一些重要方法

本文运用心电学、电生理学及相关学科知识,结合笔者多年临床经验,介绍了心律失常心电图或疑难心电图的一些重要的分析方法,如借助不应期、折返、递减传导的概念理解心律失常、利用除极向量鉴别室速、采用数学方法分析心律失常等。掌握和运用这些方法对分析理解心电图、提高疑难心电图诊断水平很有帮助。     

首次心脏事件为急性心肌梗死的冠心病患者危险因素的分析

目的:探讨首次心脏事件为急性心肌梗死(AMI)表现的冠心病患者的危险因素。方法:选取1999年1月1日-2002 年12月30日248例住院患者,116例是以急性心肌梗死为首次心脏事件的表现,列为AMI组,另外132例有心绞痛病史,经冠脉造影检查,确诊为冠心病,且无心肌梗死,列为冠心病对照组(CHD);通过Logistic回归的方法处理性别、血压、吸烟、尿酸、家族史、年龄、空腹血糖、甘油三酯、总胆固醇、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇等11个参数。结果:性别、血压、空腹血糖、甘油三酯在两组间有显著差异(P<0.01),急性心肌梗死组明显高于对照组。结论:男性,高血压的冠心病患者其首次心脏事件为急性心肌梗死的危险性较一般冠心病者显著增高。
