Bicycle stress echocardiography involves the recording and interpretation of two-dimensional echocardiographic information before, during, and after bicycle exercise. The exercise test can be performed in the supine or upright posture. While there are important physiological differences between these two positions, they appear to provide similar diagnostic information on the presence or absence of coronary artery disease. A major advantage of bicycle stress echocardiography compared to treadmill exercise is the ability to image at peak exercise, rather than relying solely on pre- and postexercise imaging. This contributes to the greater sensitivity of the test for the detection of ischemia. The recent application of digital processing techniques may also improve sensitivity by permitting side-by-side comparison of rest and stress images. In summary, bicycle stress echocardiography is a useful tool in the management of patients with known or suspected coronary artery disease. It is a versatile and accurate technique, which competes favorably with other imaging modalities and provides information on regional and global left ventricular function.
自行车运动负荷超声心动图检查包括在自行车运动前、运动期间和运动后记录和解读二维超声心动图信息。运动试验可采取仰卧位或直立位进行。虽然这两种体位存在重要的生理差异，但它们似乎能提供关于有无冠状动脉疾病的相似诊断信息。与跑步机运动相比，自行车运动负荷超声心动图检查的一个主要优势是能够在运动峰值时成像，而不是仅依靠运动前和运动后的成像。这有助于提高该检查对缺血检测的敏感性。数字处理技术的最新应用还可通过允许对静息和负荷图像进行并排比较来提高敏感性。总之，自行车运动负荷超声心动图检查是管理已知或疑似冠状动脉疾病患者的一种有用工具。它是一种通用且准确的技术，与其他成像方式相比具有优势，并能提供有关左心室局部和整体功能的信息。
