Examples of Pacemaker Codes*
I | II | III | IV | V |
|---|---|---|---|---|
Chamber Paced | Chamber Sensed | Response to Sensed Event | Rate Modulation | Multisite Pacing |
A = Atrium | A = Atrium | O = None | O = Not programmable | O = None |
V = Ventricle | V = Ventricle | I = Inhibits pacemaker | A = Atrium | |
D = Dual (both) | D = Dual (both) | T = Triggers pacemaker to stimulate ventricles | R =Rate-modulated | V = Ventricle |
D = Dual (both): For events sensed in ventricles, inhibits; for events sensed in atria, triggers | D = Dual (both) | |||
* The pacemaker code is defined by 3 to 5 letters (here defined by positions I to V). Any one of the letters may be used for each particular position. For example, in position I, the letter code may be A, V or D. In position III, the letter code may be O, I, T, or D and so on. | ||||
