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. | ||||
