A method of operating a cardiac pacing device that optimizes the mechanical heart rate using coordinated potentiation therapy while maximizing the opportunity for intrinsic AV conduction to occur. an aerodynamic structure of chord-telescopic smooth-united multisegment lifting wings; andorb. The communication includes one or more communication items which may be voice data, text data, or some other form of information. Because this temperature or heat calculation is correlated with the temperature or heat of the primary conductor, a trip routine can be added based on the measured voltage for thermal protection of the primary conductors.
