Pacemakers can be categorized according to the NASPE coding system, that usually consists of 3-5 letters.  
Pacemakers can be categorized according to the NASPE coding system, that usually consists of 3-5 letters.  
* The first letter represents the chamber where the signal is paced: A=atria, V=ventricle, D=dual (atria and / or ventricle)
* The second letter represents the chamber that is "sensed": O=none, A=atria, V=ventricle, D=dual (atrial and / or ventricle)
* The third letter represents the action that follows the sensed signal: O = none, T = triggered, I = inhibited (i.e. if the heart beats by itself, the pacemaker is silent) and D = dual (T + I).
* The fourth letter denotes whether the pacemaker has a fixed rate (0 = none) or has rate modulation (R).
* The fifth letter indicates whether the pacemaker can pace both the atria and right chamber. This letter is seldomly used.
