Clinical Observation on Treatment of 68 Cases of Refractory Ventricular Premature Systole by Oral Amiodarone 口服胺碘酮治疗难治性室性期前收缩68例临床观察
Objective To evaluate the therapeutic effect of amiodarone on refractory ventricular premature systole and its safe. 目的评价口服胺碘酮治疗难治性室性期前收缩的疗效和安全性。
The result showed that CK could correctly color encoding of the left ventricular wall motion throughout systole, therefore CK could provide the images directly and obtain the result quickly. 结果显示,CK技术能对整个收缩期的左室壁运动进行正确的彩色编码,显示方法直观,判断结果迅速。
Simulation of Mitral Regurgitation Using Ultrasonic Doppler Flow Imaging Objective To evaluate left ventricular systolic function based on mitral regurgitation during systole. 目的探讨根据收缩期二尖瓣反流评价左室收缩功能的价值。
Result: Left ventricular systole pressure and coronary artery flow were improved significantly, and the release of CK, LDH was reduced significantly with obvious reduction of myocardial infarction size in angiotensin-( 1-7) treatment group as compare to ischemic reperfusion control group. 结果与缺血再灌注对照组相比,血管紧张素-(1-7)处理组心脏左心室收缩压、冠状动脉流量显著提高,冠状动脉循环流出液中肌酸磷酸激酶、乳酸脱氢酶含量降低,心肌梗死范围减小。
This study of methodology was aimed to assess the feasibility of measuring different phase of left ventricular systole period with ultrasonic Doppler and synchronism electrocardiogram. 探讨以多普勒超声结合同步心电图定义左室收缩期时相的可行性。
In the left ventricular outflow tract during diastole were similar echoes which returned to the aortic root during ventricular systole. 在舒张期左室流出道有相似的回声,而在收缩期,此回声又回到主动脉根部。
Method for Measuring Different Phases of Left Ventricular Systole Period with Ultrasonic Doppler and Synchronism Electrocardiogram in Normal Persons 多普勒超声与同步心电图测定正常人左室收缩期时相的方法学研究
Methods: Powerlab biology signal analysis system was used to record arterial pressure, ECG, the biggest function of ventricular systole, the biggest function of ventricular diastole, dp/ dtmax and-dp/ dtmax in synchronism and movements. 方法:采用powerlab生物信号记录分析系统同步动态记录动脉血压、II导心电图、心室最大收缩功能、心室最大舒张功能、左室内压最大上升速率(dp/dtmax)、左室内压最大下降速率(-dp/dtmax)。
Three cases had main pulmonary artery stenosis. Color Doppler showed two direction shunt at the location of VSD and no color flow through right ventricular outflow tract to pulmonary artery on systole. 彩色多普勒均显示室间隔缺损处双向分流,收缩期右室流出道至主肺动脉血流束中断,1例降主动脉至主肺动脉五彩样分流束。
Objective To evaluate the left ventricular systolic function of the old antero-septal myocardial infarction by measuring the mitral annular velocity in systole using tissue Doppler echocardiography. 目的采用多普勒组织成像技术(TDE)测量二尖瓣环收缩期下行速度,评价陈旧性前间壁心肌梗死患者的左室收缩功能。
Dynamics of left ventricular systole during progressive exercise in sitting position 直立位递增运动负荷时左室收缩期血流动力学变化
The rates of left ventricular dysfunction of systole and diastole were 16.67% and 76.67% respectively and the former had abnomal diastolic function. The incidence of normal function of LV was 23.33%. 左心室舒张功能异常发生率为76.67%,左心室收缩功能减退为16.67%,均伴有舒张功能异常,左心室功能相对正常为23.33%,左心室舒张功能异常出现早于左心室肥厚;
Results Ventricular wall motion colour in thyroidism group was brighter than that in the normal group. On Doppler wave, every speed of wave peak in both systole and diastole in thyroidism group was faster than that in the normal group. 结果甲亢组室壁运动色彩较正常组明亮,频谱多普勒曲线上,甲亢组在收缩期、舒张期室壁运动各峰值均大于正常组,两组有显著差别(P0.01)。
Furthermore, the improvement of left ventricular diastolic function was also superior in the treatment group ( p < 0. 01). Traditional treatment also improved the function of left ventricular systole. 同时治疗组改善左心室舒张功能的作用也优于对照组(P<0.01),且中药对左心室收缩功能也有一定改善作用。
