As a result, confirm that the electrode patches are fresh and connected to the sensor properly. A drawing on the sensor box shows the proper connections. Note that electrode tabs do not work as well if they are old or have been allowed to dry out. Also, results vary form person to person. If an individual always has trouble getting a clean signal, try alcohol swabs before affixing the electrodes.<\/li>\n<li><strong>Secondary Test: <\/strong>Make sure that the person connected to the sensor is seated or lying down and that they are relaxed.<\/li>\n<\/ul>\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h3 class=\"wp-block-heading\">Additional Troubleshooting<\/h3>\n<ul class=\"wp-block-list\">\n<li><a href=\"\/til\/2036\/\">Why is my EKG trace noisy?
