Heart rate response to shock delivered via different implanted electrodes.
The heart rate reaction elicited by electric shock was studied in rats stimulated via implanted electrodes that were placed entirely beneath the skin (subcutaneous electrodes) or were passed under and through the skin (cutaneous electrodes). Cutaneous shock elicited greater cardioaccelerations than subcutaneous shock except at very low intensities. This finding may help to explain differences in conditioned heart rate responses when these two types of electrodes are used to deliver shock stimuli.
