If a patient has a limb amputated, where would the electrode be placed?

In the context of placing an electrocardiogram (EKG) electrode for a patient who has had a limb amputated, the best practice is to tape the electrode on the site of the amputation. This is crucial because the EKG measures the electrical activity of the heart, and the positioning of the electrodes is necessary to obtain accurate readings.

When a limb is amputated, the corresponding electrode cannot be placed on that limb. Instead, placing the electrode directly on the site of the amputation can help maintain the appropriate electrical circuit required for the EKG. This approach allows for better detection of the heart's electrical signals while accommodating the anatomical changes due to the amputation.

Utilizing the remaining limb or the opposite limb could introduce inaccuracies in the EKG readings due to potential interference or differences in electrical pathway conduction. Similarly, placing the electrode on the torso may not adequately capture the electrical signals in the same way as placing it on the amputation site would, therefore making it less ideal.
