Which of the following is NOT a sensitivity pre-set option in the current DC ICD?

Which of the following is NOT a sensitivity pre-set option in the current DC ICD?

• A. STD
• B. TWS
• C. VFS
• D. GPS

Answer: (D)

Sensing sensitivity in a DC ICD is about how readily the device interprets electrical signals as ventricular activity, with predefined presets that tailor detection to balance accurate therapy against oversensing noise. Among the listed options, STD stands for a standard sensitivity preset, and TWS and VFS are specialized sensitivity configurations used to adjust how the device senses signals under different conditions. GPS, on the other hand, is not part of the sensitivity settings; it’s not used to determine how the ICD detects cardiac signals and is not a sensitivity preset. Therefore, GPS is the option that does not fit.
