WebD = Dual pacing (pacing in the atria and ventricles). D = Dual sensing (sensing in the atria and ventricles). D = Dual response (can be both inhibited and triggered). R = Rate responsive (the pacing rate can adapt to physical activity). In clinical practice, DDD, VVI, and AAI are most common, with or without rate responsiveness.
