Abstract:ObjectiveTo explore the equivalence of performance between domestic and imported ECG machines. [WTHZ]MethodsOne hundred subjects were randomly divided into group A and B, each with 50 cases. In group A, routine 12lead ECG was recorded simultaneously by ECG machine produced by Wuhan Zoncare Company(type 1) and ECG machine produced by General Electric Company(type 2). In group B, routine 12lead ECG was recorded simultaneously by type 1 ECG machine and ECG machine produced by Philips Electronics(type 3). The three types of ECG machines were set the same collection parameters, connected the lead wires of different types of machines with three links, and collected the routine 12lead ECG signals of the same subject simultaneously and synchronously. [WTHZ]ResultsEight parameters and the amplitude of each waveform automatically measured by the equipments were analyzed by three statistical methods. Analysis results all confirmed that there was no statistical difference between the data separately obtained by domestic and imported ECG machines. It demonstrated good consistency and correlation of the data. [WTHZ]ConclusionThe objective data supports the equivalence of performance between domestic and imported ECG machines. And our fellow countrymen can utilize the domestic ones with confidence.
