Electrode Indicates the electrode placement positions in the torso image. Placement Red LED: Indicates a bad electrode connection, based on the Acquisition Image with LEDs Module detecting a high impedance associated with that electrode. Reasons typically include insufficient patient skin preparation, faulty/dry electrode, faulty cable, faulty lead connector. Green LED: Indicates a good electrode connection, based on the Acquisition Module detecting a low electrode impedance. When all the LEDs are green, the ECG is of good quality to use for diagnostic purposes.
