Abstract

Twenty patients with DDD pacemakers had their intracranial cerebral circulation assessed in different pacing modes, using transcranial Doppler. The studies were performed at the vertebral artery in a sitting position. Although DDD pacing was pre/ered to VVI pacing in 18 of the 20 patients, the figures did not reach statistical significance. There was no stotistical difference in maximal blood flow velocity between DDD pacing at 60 and 80 beats/min. Varying the AV interval from 150–250 msec also demonstrated no clear difference in maximal peak Doppler velocity, in the group as a whole, though there was a greater individual preference for 150 msec. Transcranial Doppler assessment of the hemodynamics of the cerebral circulation is of limited value as an indicator of mode or rate preference in the pacemaker population.
