In addition, ShockGuard technology features specific programming that distinguishes between rhythms that require defibrillation therapy and those that do not, such as benign arrhythmias
While most ICD-delivered shocks are needed, previous studies estimated that approximately 20 percent of patients with ICDs may experience inappropriate shocks in response to benign arrhythmias
or electrical noises sensed by their devices.
The study results also revealed that the portion of patients receiving inappropriate shocks, or unnecessary therapy delivered in response to benign arrhythmias
or electrical noise sensed by the device, was low and not different between groups.
