Consequently, electrical signals from other sources, such as those generated by an electrosurgical unit, may be incorrectly interpreted by these devices as cardiac activity. This can provoke an inappropriate response, such as the inhibition of stimulus emissions (the problem most often observed). More rarely, with dual-chamber pacemakers, ventricular pacing may occur at a higher frequency than normal if the interference is interpreted as atrial activity. Asynchronous pacing can also occur (emission of stimuli at a fixed frequency regardless of cardiac activity) or response algorithms may be activated, leading the device to switch to automatic mode or ventricular safety pacing. Exceptionally, direct contact between the electrosurgical energy source and the pacemaker's pulse generator casing may damage the circuits or, if the current should pass through the pacemaker leads, cause heat injury to the heart and loss of stimulation.<a class="elsevierStyleCrossRefs" href="#bib0010"><span class="elsevierStyleSup">2,6,7,12,13,15</span></a></p><p id="par0095" class="elsevierStylePara elsevierViewall">In AICDs, interference could provoke the inappropriate delivery of impulses or inhibition of the pacing system, which would leave the patient without protection in the event of asystole.<a class="elsevierStyleCrossRefs" href="#bib0045"><span class="elsevierStyleSup">9,12,15</span></a></p></span><span id="sec0055" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle">Location of the Lesion</span><p id="par0100" class="elsevierStylePara elsevierViewall">The location of the skin lesion to be treated is a very important aspect that must be taken into account when considering electrosurgery in patients with IECDs.
