1. A cardiac pacing apparatus, for artificially stimulating contractions in a heart of an animal, comprising:

  • a power transmitter which periodically transmits a pulse of a radio frequency signal;

    a first electrode and a second electrode for implantation in the animal; and

    a vascular electrode-stent for implantation in a blood vessel of the animal and comprising a pickup device for receiving the radio frequency signal and a cardiac signal emitted from a sinus node of the heart, and a pacing signal circuit connected to the pickup device and having an electrical storage device, wherein the pacing signal circuit charges the electrical storage device with electrical energy from the radio frequency signal and in response to detecting the cardiac signal determines when stimulation is required and applies a stimulation voltage pulse across the first electrode and the second electrode to cause a contraction of the heart.
