Abstract:
Objective To analyze the power interference during ECG machine testing and to propose countermeasures.Methods Some measures in power supply stability, shielding, grounding and wire winding were carried out to reduce the influences of 50 Hz interference on ECG machine testing.Results The influences of the power interference were reduced greatly on ECG machine.Concluslon The performances of ECG machine can be ensured by restraining the power interference.
