心电图机是医院中最为普及的医用电子仪器之一,主要的功能是记录心脏活动时所产生的生理电信号。我国目前的心电图机技术还算比较成熟,因为价格适中,对人身体没有实质性的伤害,所以病人都比较能够接受这种技术。在医疗诊断过程中,心电图机的功能一旦异常,就会导致临床诊断错误,进而造成更严重的后果,所以心电图机技术指标中的灵敏度、阻尼和时间常数是衡量一台心电图机的重要指标,我们需要了解这些指标的真正意义并掌握正确的检测方法。
Electrocardiograph is one of the most popular medical electronic instruments in a hospital. Its main function is to record the physiological signals generated by heart activity. The current ECG technology in China is still relatively mature, because the price is moderate, no substantial harm to the human body, so patients are more able to accept this technology. In the medical diagnosis process, the function of the ECG once abnormal, it will lead to clinical diagnosis errors, and then cause more serious consequences, so the sensitivity of electrocardiogram technical indicators, damping and time constant is an important indicator of an ECG machine, We need to understand the true meaning of these indicators and master the correct test method.
