Methods 104 patients with severe heart failure were divided into two groups. The control group was treated with routine treatment (digitalis,diuretic and distend the blood-vessel) combined with Imidapril (group A,n=52). The treatment group was treated with routine treatment (digitalis,diuretic and distend the blood-vessel) combined with Bisoprolol and Midapril (group B,n=52). The course of treatment was 12 to 16 weeks. Before and after treatment,the changes of heart function,LVEF,LVESD,heart rate and blood pressure were observed.

对104例重度心力衰竭患者随机分成两组：对照组52例，予以常规用药及咪达普利等药物治疗；治疗组52例，在常规用药基础上加用比索洛尔治疗，疗程12～16周，观察治疗前后心功能、左室射血分数、左室舒张末内径、左室收缩末内径、心率、血压等指标的变化。

In aneurysm larger than 50% of the left ventricular volume, patch ventriculoplasty is superior to linear closure in maintaining normal left ventricular form and protecting left ventricular function.

左室容积50％的大型室壁瘤，补片成形术在保持左室正常形态和保护左室功能等方面优于直接缝合术。

Some electrophysiological index were measured, including atrial effective refractory period, rate adaptability, dispersion of AERP, inducibility and duration of induced atrial fibrillation under different basic pacing cycle length (300, 250 and 200 ms). Results: Contrast with control group, the values of AERP at 6 sites were shortened and maladaptation.

将6对双极记录电极分别缝于高位左、右和低位左、右心房外膜以及左、右心耳，采用心脏程序期前刺激法(S1S2)，分别测量基础起搏周长为300、250和200ms时的心房有效不应期、AERP频率适应性、AERP离散度、房颤诱发率及平均持续时间等电生理指标。

The primary end point was the incidence of atrial fibrillation. The second end points were New York Heart Association cardiac function class, changes in left atrial and left ventricular end-diastolicdiameters, as well as left ventricular ejection fractionmeasured by echocardiography.

主要研究终点为房颤的发生率，次要终点为心功能分级及超声心动图检查指标(左心房内径、左心室舒张末期内径、左心室射血分数)。

Methods:A validated three dimension reconstructional echocardiographic technique for endocardial surface area was used to measure the endocardial surface area of the left ventricleand abnormal wall motionin 70 consecutive patients with first AMI.Patients undertook serial echocardiogram on the day 1,3 and 2 weeks,3 and 6 months after admission.

应用超声心动图数据处理系统重建并定量急性心肌梗塞患者的左室心内膜三维面积、异常运动区心内膜三维面积同时测量左室射血分数，系列观察70例患者急性心肌梗塞后左室重塑的动态演变特征及其对左室功能与预后的影响。

LAA mechanical activity prior to ECV is highly related to maintenance of sinus rhythm in NVAF, and LAA "stunning" developed a thrombogenic milieu. Patients with atrial fibrillation should be given full anticoagulation to prevent thrombogenesis in left atrial and LAA.

NVAF患者电转复前左心耳收缩功能与窦性心律的维持高度相关；转复后左心耳&顿抑&，出现了血栓易于形成的条件，故对此类患者电转复后应给予足够的抗凝治疗，预防左房与左心耳血栓形成。

Measurirg indxes included:(1) Electrocardiograh;(2) Hemodynamics: cardiac output, pump output, aortic pressire, pulmo nary artery pressure, left atrium pressure, right atrium pressure, left ventricular end systolic pressure, left ventricular end diastolic pressure, LV-dp/dt, right ventricul ar end systolic pressure, RV-dp/dt, systolic pressure time index, diastolic pressure time index, endocardial viability ratio;(3) Myocardial metabolism: coronory sinus blood flow, myocardial oxygen consumption, myocardial lactate extractiorn;(4) Ischemic myocardial area;(5) Ultrastructure of myocardium.
