Combination of sensors to provide optimal pacing rate response.
Previously, single-chambered rate-adaptive and dual-chamber pacemakers have been considered as alternative methods of providing rate response. Neither can adapt to changing circumstances and each has its own benefits and limitations. The development of units combining both facilities expands the range of conditions for which atrioventricular sequential pacing is possible and will ensure appropriate and adequate rate response at all times. At present, change in pacing mode is dependent on physician programming, but future generations will have the ability to diagnose the intrinsic rhythm and then prescribe automatically the pacing modality of choice.
