Echocardiogram
超声心动图
An echocardiogram is a common test using sound waves to map out the shape and size of your heart, thus allowing your doctor to see how well your heart pumps blood and look for abnormalities of the heart valves and chambers.
超声心动图是一种使用超声波，探查心脏的形态和大小，从而了解的心脏的泵血情况，检查心脏瓣膜和心室异常情况的常见检查方法。
In a transthoracic echocardiogram, your sonographer will put a cool gel on your chest. Your sonographer will move a transducer firmly through the gel, sending painless sound waves to your heart.
在行经胸超声心动图检查时，超声医师将在被检查者胸部涂抹一层冷凝胶。超声医师将通过凝胶，稳固地移动换能器，向心脏发送无痛声波。
The sound waves bounce off your heart and echo back to the transducer. The sound waves are converted to moving images of your heart muscles, chambers, and valves on a video screen.
声波从心脏反弹回来，并反射回换能器；在视频屏幕上转换为心肌、心腔，以及瓣膜的运动图像。
A doppler echocardiogram records echoes from blood cells. The speed and direction of the blood flow indicate how well blood gets around inside your heart.
多普勒超声心动图记录血细胞的回声。血液流动的速度和方向表明血液在心脏内的流动情况。
A stress echocardiogram evaluates images of the heart before and after exercise, or following medication that simulates exercise on the heart.
负荷超声心动图评估运动前后的心脏图像，或服用模拟心脏运动对心脏影响的药物后的心脏图像。
Comparing your echo results before and after activity provides your doctor information about certain heart problems, such as coronary artery disease, that may only occur with exertion.
医生可以通过对比活动前后的超声检查结果，了解仅伴随运动发生的某些心脏问题，如冠状动脉疾病。
A transesophageal echocardiogram sends sound waves through a transducer passed gently down your throat while you are under sedation. This test provides a closer, more detailed evaluation of your heart.
经食管超声心动图是在被检查者处于镇静状态时，通过换能器，轻轻地沿喉向下发送声波的检查。这种检查能够更清晰、详细地评估心脏的情况。
