In cardiac pacemaker coding, what does the first letter represent?

Explanation:
The first letter in the pacemaker code indicates which chamber is paced. This code, often referred to as the NBG code, uses the first letter to specify the pacing site—A for atrial pacing, V for ventricular pacing, and D for dual-chamber pacing. It isn’t about sensing, the response to sensing, or the overall pacing mode; those aspects are described by the other letters. So, the correct interpretation is that the first letter represents the chamber being paced.
