Comparison of two different approaches to address the problem of malfunctioning ICD-leads. These leads consist of two parts. One that is used for detection of arrhythmias(and pacing if required) (Pace/Sense) and a second part that is used to deliver therapy is needed (Shock-coil). The two approaches compared are: Replacement of the entire lead in case of any lead malfunction versus placement of an additional pace/sense-lead if the shock-coil of the exiting lead was still functional.
