心脏二维超声和彩色多普勒血流显像对室间隔缺损的诊断价值

Methods: The various left ventricular function indexes of elderly idiopathic patients with persistent AF ( group ⅰ), paroxysmal AF ( group ⅱ), and after cardioversion ( group ⅲ) were determined by two dimensional and doppler color echocardiogram, compared with normal elders ( control group).

方法：采用彩色多普勒二维超声心动图仪测定老年人持续、阵发性房颤及房颤复律后左心功能的各项指标，并与健康老年人进行对照。

METHODS: The apical four chamber view of 8 athletes under endurance training and 8 without training were recorded with two dimensional echocardiogram at rest, during exercise, and the end of 1 min, 2 min, 3 min after exercise, and were analyzed later.

方法：采用二维超声心动图分别记录8名耐力训练者和8名无训者安静状态下、运动中、运动后1,2,3min末心尖四腔图，并对图像进行分析处理。

Methods Forty-one patients ( 52.3 ± 9.8 years) with Q wave myocardial infarction underwent low-dose dobutamine electrocardiography and echocardiography before revascularization, revascularization was performed in all patients. Resting echocardiogram was repeated two month after revascularization.

方法41例近期心肌梗死患者，于血管重建术前行低剂量多巴酚丁胺超声心动图（Low-DoseDobutamineEchocardiography，LDDE）和负荷心电图检查，术后两个月重复静息超声心动图检查。
