Abstract
We present a case of an individual who was found to be emanating a sound from her implantable cardioverter defibrillator (ICD). She had developed breast carcinoma requiring mastectomy and breast tissue expander implantation. The magnetic port on the breast tissue expander led to electromagnetic interference and magnet mode conversion. The ICD’s conversion to magnet mode can be dangerous, because it blocks tachyarrhythmia detection and therapy.
