Abstract:
An audible alarm from an implantable cardioverter defibrillator (ICD) can provoke considerable anxiety in the patient. An alarm may result from several causes, some of which require urgent attention. A knowledge of the different types of audible alerts as well as methodical device interrogation is needed to unravel the cause of ICD alarms. The present case instructively illustrates the systematic approach to a patient presenting with an audible alarm from an ICD, discusses appropriate management and details of the relevant device algorithms involved.
