A simple technique for obtaining high-quality echocardiograms of the left ventricle during upright bicycle exercise is described. The use of this method has resulted in left ventricular dimension data that are consistent with the results of studies in conscious, previously instrumented dogs during running. Careful subject selection is important, however, as only 1 of 5 normal subjects was found suitable for these studies. Therefore, we believe that upright exercise echocardiography is feasible in selected subjects and provides useful physiologic information about left ventricular performance during exercise.
本文描述了一种在直立自行车运动期间获取高质量左心室超声心动图的简单技术。使用该方法所得到的左心室尺寸数据与在有意识的、先前已植入仪器的犬类跑步研究结果一致。然而，仔细选择受试者很重要，因为在5名正常受试者中仅发现1名适合这些研究。因此，我们认为直立运动超声心动图在选定的受试者中是可行的，并能提供有关运动期间左心室功能的有用生理信息。
