An Atypical Presentation of Twiddler's Syndrome: A Case Report.

The prevalence of implanted pacemaker/defibrillator devices continues to rise. Automatic implantable cardioverter-defibrillator (AICD) lead displacement (Twiddler's syndrome) is an uncommon form of the device malfunction, usually presenting with cardiac symptoms. We present a case of Twiddler's syndrome with an atypical presentation, accompanied by critical alkalosis on arterial blood gas. Considering Twiddler's syndrome as part of the differential diagnosis in patients with implanted devices and utilizing remote ICD interrogation may improve the care of patients presenting with device malfunction.
