T wave oversensing by a cardioverter defibrillator implanted in a patient with the Brugada syndrome.
Oversensing of electrical signals in recipients of ICDs is a common complication causing the delivery of inappropriate therapy. The Brugada syndrome has a characteristic ECG pattern with dynamic temporal changes in response to various physiological or environmental conditions. This case report presents a patient with the Brugada syndrome and intermittent T wave oversensing by an ICD due to changes in T wave amplitude which could not be resolved by device reprogramming and required repositioning of the electrode.
