AHA Diagnostic ECG Electrode Placement The quality of an ECG is dependent on the preparation and the resistance between the skin and the electrode. To ensure a good quality ECG and minimize the skin/electrode resistance, remember the following points: 1.) Ensure that the patient is warm and relaxed 2.) Shave electrode area before cleaning 3.) Thoroughly clean the area with alcohol 4.) Let dry prior to applying electrode
Resting ECG RA and LA electrodes should be placed on the wrists. RL and LL electrodes should be placed a few inches above the ankle.
