活动平板运动试验(TET)作为筛查和辅助诊断冠心病的一种简单经济的方法,目前仍广泛地应用于临床。但是由于日常工作量大,仪器使用频率高,在检查过程中容易受到多种因素影响出现干扰现象,产生异常波形,使正常波形变形[1],在心电波形上呈伪心律失常,伪ST-T改变,以及各种伪差样改变以致图形紊乱难以辩认,影响对运动试验检查结果的判断,为保证检查结果的客观准确,我们针对常见干扰原因进行分析并采取相应对策,取得了良好的效果。
Active treadmill exercise test (TET) as a simple and economical method of screening and diagnosing coronary heart disease is still widely used in clinic. However, due to the daily workload, the high frequency of the instrument, the inspection process is susceptible to interference caused by many factors, resulting in abnormal waveform, the normal waveform deformation [1], showed pseudo-arrhythmia on the ECG waveform, pseudo ST- T changes, as well as a variety of changes in the pseudo-like pattern so difficult to identify the disorder, affecting the test results of exercise test judgments, in order to ensure the objective and accurate test results, we analyze the causes of common interference and take appropriate measures to achieve a good effect.
