测量指标:

Outcomes:

指标中文名:

左房内径

指标类型:

主要指标

Outcome:

Left atrial diameter

Type:

Primary indicator

测量时间点:

入组前与观察结束时

测量方法:

采用M型超声测量方法,从主动脉后壁前缘测量到左心房后壁前缘,与主动脉根部垂直。

Measure time point of outcome:

Before enrollment and at the end of observation

Measure method:

Using M-mode ultrasound measurement method, measure from the anterior edge of the posterior wall of the aorta to the anterior edge of the posterior wall of the left atrium, perpendicular to the aortic root.

指标中文名:

左室内径

指标类型:

主要指标

Outcome:

Left ventricular diameter

Type:

Primary indicator

测量时间点:

入组前与观察结束时

测量方法:

采用M型超声测量左室内径,采用胸骨旁长轴切面,M型取样线置于二尖瓣瓣尖,取样线尽量与室间隔垂直,以血液与组织交界处为界点。

Measure time point of outcome:

Before enrollment and at the end of observation

Measure method:

M-mode ultrasound was used to measure the left ventricular inner diameter, and a parasternal long axis section was taken. The M-mode sampling line was placed at the mitral valve apex, and the sampling line was as perpendicular as possible to the interventricular septum, with the blood tissue junction as the boundary point.

指标中文名:

射血分数

指标类型:

主要指标

Outcome:

Ejection fraction

Type:

Primary indicator

测量时间点:

入组前与观察结束时

测量方法:

采用辛普森法,首先探测心尖部四腔和二腔切面,保存图像;通过轨迹球,在心尖部四腔和二腔切面,测量左心室舒张末容积(LVEDV),然后再测量收缩末期容积(LVESV),得到EF=(LVEDV-LVESV)/LVEDV╳100%

Measure time point of outcome:

Before enrollment and at the end of observation

Measure method:

Using the Simpson method, first detect the four chamber and two chamber sections of the apex of the heart, and save the images; Using a trajectory ball, measure the left ventricular end diastolic volume (LVEDV) in the apical four chamber and two chamber sections, and then measure the end systolic volume (LVESV) to obtain EF=(LVEDV LVESV)/LVEDV x 100%

指标中文名:

瓣膜反流程度

指标类型:

主要指标

Outcome:

Degree of valve regurgitation

Type:

Primary indicator

测量时间点:

入组前与观察结束时

测量方法:

根据二尖瓣反流束长度到达左心房的不同部位半定量反流程度。轻度反流:瓣环水平反流束达到左心房的下1/3。中度反流:心房中部反流束达到左心房的1/3-2/3。重度反流:达到心房顶部或肺静脉内反流束超过左心房的2/3

Measure time point of outcome:

Before enrollment and at the end of observation

Measure method:

According to the length of the mitral regurgitation tract, the degree of semi quantitative regurgitation reaches different parts of the left atrium. Mild regurgitation: The regurgitant bundle at the annulus level reaches the lower one-third of the left atrium. Moderate regurgitation: The regurgitant bundle in the middle of the atrium reaches one-third to two-thirds of the left atrium. Severe regurgitation: Reaching the top of the atrium or pulmonary venous reflux tract exceeding 2/3 of the left

随机方法(请说明由何人用什么方法产生随机序列):

1.根据患者24小时动态心电图报告的平均心室率水平将患者分为四组:I组(40次/分≤平均心室率<60次/分)、II组(60≤平均心室率<80组)、III组(80≤平均心室率<100)和IV组(平均心室率≥100次/分)。 2. 抽样方法 采用分层抽样的方法,随机选择每组符合条件的患者,直到每组的样本量达到200,然后不再对该组进行采样。

Randomization Procedure (please state who generates the random number sequence and by what method):

1. According to the average ventricular rate level reported by the 24-hour dynamic electrocardiogram, patients were divided into four groups: Group I (40 beats/min ≤ average ventricular rate<60 beats/min), Group II (60 ≤ average ventricular rate<80 groups), Group III (80 ≤ average ventricular rate<100), and Group IV (average ventricular rate ≥ 100 beats/min). 2. Sampling method Using a stratified sampling method, randomly select each group of eligible patients until the sample size of each group reaches 200, and then no further sampling will be conducted for that group.
