Appropriate Delivery of Antitachyarrhythmia Therapy Despite Magnet Placement Over Implanted Cardioverter-Defibrillator: A Case Report.

The fundamental perioperative concern for patients with implantable cardioverter-defibrillators (ICDs) is the potential for electromagnetic interference (EMI) from monopolar electrosurgery. The ICD may interpret electromagnetic signals as a tachyarrhythmia and deliver an inappropriate shock to the patient. Magnet placement is often used to avoid this problem since a magnet will often deactivate an ICD's tachyarrhythmia therapy. We report a case in which magnet placement over an ICD failed to suspend tachyarrhythmia therapy because of imprecise magnet positioning. This case demonstrates the possibility for error when relying on a magnet to suspend tachyarrhythmia therapies.

Management of complications with hand fractures.

Both operative and nonoperative treatment of hand fractures can result in numerous complications, including stiffness, malunion, nonunion, arthritis, infection, and complex regional pain syndrome. These complications are frequently encountered and are often challenging to treat. This article systematically outlines the diagnosis and treatment of each of these complications to achieve the best possible outcome for the patient's overall hand function.
