In the NBG Device code, the second letter refers to which of the following?

• A. Chamber sensed
• B. Therapy delivered
• C. Lead configuration
• D. Device type

Answer: (A)

The second position in the NBG device code shows which chamber the device senses. It indicates whether sensing occurs in the atrium, in the ventricle, or in both chambers. This helps determine how the device detects intrinsic activity to decide whether pacing is needed. It’s not about how leads are configured, nor about the device type itself, and the third position handles the therapy delivered or the response to sensing. So the correct idea is that this position specifies the chamber that is sensed.
