CASE REPORT
Automatic R-wave and impedance testing with the modern patient alert system to reduce inappropriate implantable cardioverter defibrillator shocks due to lead fracture

A 62-year-old man was afflicted with implantable cardioverter defibrillator (ICD) shocks during sinus rhythm. Stored ICD data revealed that sensing of noise due to fracture of the ventricular lead triggered the delivery of shocks. Since the lead fracture developed suddenly, it is suggested that close, early attention should be paid to the potential of such events during follow-up of ICD leads.
