Objective To assess left ventricular asynchrony in patients with left bundle branch block by quantitative tissue velocity imaging.

目的应用定量组织速度成像技术研究左束支传导阻滞患者左心室运动的不同步性。

For example, a blockage in the right bundle branch of the intraventricular conduction system produces a particular set of characteristic ECG signals.

Objective To assess the synchrony in bundle branch block.

目的 探讨束支传导阻滞患者心室壁机械运动同步状况。

Methods The investigation included 56 patients,43 male and 13 female,mean age of 52.9 years,with refractory chronic heart failure and left bundle branch block.

慢性心衰伴心室内传导延迟患者56例，男性43例，女性13例，平均年龄52.9岁。

Just like the mitral valve, the leaflets have thin chordae tendineae that attach the leaflet margins to the papillary muscles of the ventricular wall below.

与二尖瓣一样，瓣叶有薄博的键索连接着瓣叶边缘与心室壁上的乳头肌。

TEE revealed that balloon catheters were embedded in chordae tendineae of mitral valve 18 times in 12 patients.Except 3 cases developing moderate mitral regurgitation from mild regurgitation,the other cases didn't develop mitral regurgitation or have mitral regurgitation worsened.

TEE显示12例18次球囊导管进入左心室过程中嵌入腱索，及时退出导管。3例患者扩张后由二尖瓣轻度关闭不全转变为中度关闭不全，其余患者术后无二尖瓣关闭不全或程度无加重。

Group I:Completely resection of the mitral leaflets, chordae and tendineae, and papillary muscles; group Ⅱ:Preservation of the posterior leaflets and subvalvular structures;group Ⅲ:Completely preservation of the mitral complex.4h, 24h and 48h after operation, Swan-Ganz catheter was used to measure hemodynamic index: Mean pulmonary arterial pressure,pulmonary vascular resistance,pulmonary capillary wedge pressure,systemic vascular resistance,cardiac index and left ventricular stroke work index.

组：常规MVR，切除全部二尖瓣瓣叶及其瓣下结构；Ⅱ组：保留后瓣及其瓣下组织；Ⅲ组：全部保留二尖瓣装置。术后4小时、24小时和48小时分别采用Swan-Ganz导管测定血流动力学指标：平均肺动脉压、肺毛细血管嵌压、肺血管阻力、外周血管阻力、心脏指数和左心室每搏作功指数。

Methods The whole cell patch clamp technique was used in isolated ventricular cells of guinea pigs.

用膜片钳实验技术记录胶原酶急性分离的豚鼠心室肌细胞钾通道电流。

Whole cell recording of isolated cells was easily performed by the whole cell patch clamp technique.

肥大和衰竭心脏的心室肌细胞重新表达if，可能与心律失常的发生有关。

Whole cell patch clamp technique was used to investigate the effect of sinomenine on sodium current and L-type callium in isolated guinea pig ventricular myocytes.

应用膜片钳全细胞记录技术研究青藤碱对酶解分离的豚鼠单个心室肌细胞膜钠离子电流、L型钙电流的影响。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
