心电图检查目前已成为一种临床诊断心血管疾病常用的检查方法之一。为了做出正确的诊断,心电图的记录必须准确、清晰;心电图机必须完好,无故障;工作者必须是操作熟练并有一定维修经验的人员。而目前基层临床心电图工作者,部分人员未经过专业心电图机维修训练,手边又无维修仪器(如万用电表、通用示波器等),为保证临床工作顺利进行,必须掌握购置理想心电图机的方法,机器的正确使用,常见故障的分析和处理。本文将重点讨论在没有更多检查仪器情况下,使用心电图机标准信号进行校验的方法以及临床常见故障的排除。
Electrocardiogram has now become a commonly used method of clinical diagnosis of cardiovascular disease. In order to make the correct diagnosis, ECG records must be accurate and clear; ECG machine must be intact, trouble-free; workers must be skilled and have some maintenance experience of the staff. At present, the primary clinical ECG workers, some staff without the maintenance of professional ECG machine training, no maintenance of instruments at hand (such as multimeter, general oscilloscope, etc.), in order to ensure the smooth progress of clinical work, we must master the purchase of the ideal ECG machine method , The correct use of the machine, analysis and treatment of common faults. This article will focus on the absence of more instruments to check the case, the use of ECG standard signal calibration methods and clinical troubleshooting.
