MECG 2.0 is a test device that can simultaneously generate 8 channel signals. It is mainly applicable to the database test of various ECG equipment. Medical regulations require ECG equipment manufacturers to use specific databases to evaluate the system

It is normal in ECG testing to simplify the approach on the assumption that one test is representative. For example, an input impedance test on V1 and V4 can reasonably be considered representative of tests on the other chest leads.

Although not explicitly stated, it’s obvious the ECG standard includes noise. If a test requires the ECG under test to reproduce a test signal accurately within ±5%, it makes no sense to perform the test if the test signal also had said ±20% noise.

Recently Derek Qin of Draeger pointed out that at the end of the MEDTEQ article on ECG filters, the graph showing the effect of a 3mV/100ms impulse on a 0.05Hz high pass filter had a post impulse slope that looked more like 29µV rather than the claimed 29

Respiratory rate is defined as the measurement of a person's breathing rate per minute at rest. In clinical diagnosis, respiratory rate is widely used to evaluate physiological indicators, especially for sleep and stress analysis.

The linearity and dynamic range of the amplitude are important factors that affect the amplitude accuracy of ECG device. The dynamic range determines the ECG device maximum range of the amplitude linearity.

Electrocardiogram (ECG) is the easiest way to examine cardiac problems. There are many ECG device developer devoted to offer sophisticated and accurate ECG devices for medical institutions and public. Before the government permits to release those ECG

Input impedance is an important factor that affects the accuracy of the ECG. Therefore, each ECG must test the input impedance. This article will explain the principle of input impedance and calculate the value of the input impedance of the ECG

Basically, the basic performance tests in all types of ECG machines should be based on the items that are used to test the basic safety and essential performance of electrocardiographs as specified in the three international ECG standards.

In the ECG performance standard IEC60601-2-47 has disclosed to evaluate HRV algorithm performance using artificial ECG signal. In subclause 201.12.1.101.2.3.3.2, there are two methods (analogue and digital). For fully compliance standard, it is better to
