Diathermy and the cardiac implantable electronic device
Primary physics & clinical — the high-frequency electromagnetic interference causing the pacemaker oversensing/inhibition and the ICD misclassification (an inappropriate shock), the magnet response (the pacemaker asynchronous mode versus the ICD tachytherapy suspension), the bipolar preference, the return plate placement, and the pre- and post-operative interrogation.

Prompt
Outline the perioperative management of a patient with a cardiac implantable electronic device (a pacemaker or an ICD) presenting for surgery requiring surgical diathermy: the mechanism of the diathermy interference, the magnet response, the precautions, and the post-operative care.
