Why does my Spengler LeECG Medical Equipment show AC interference?
- GGabriel RodgersAug 14, 2025
AC interference on your Spengler Medical Equipment, presenting as a 50Hz sine wave overlap with amplitude and jitter on the ECG baseline, can stem from several factors. Ensure the device and patient bed are properly grounded. Verify correct electrode and leadwire connections, and sufficient conductive paste application. Avoid patient contact with conductive objects and nearby powerful electrical equipment. Confirm the patient isn't wearing metal ornaments and the AC filter frequency is correctly set. If issues persist, utilize an AC filter, noting it may slightly attenuate the recorded waveform.
