An electronic pacemaker for implantation in a body of a living being including an electrode portion that is configured to be attached to a body portion； an electronics assembly connected with the electrode portion, configured to generate a voltage impulse emitted via the electrode portion to the body portion； a rechargeable accumulator to supply the electronics assembly with electrical energy； and a charging impulse generation portion electrically connected to the accumulator, configured to emit a charging impulse to the accumulator for the recharging of the accumulator. The charging impulse generation portion includes a magnetization portion with oriented magnetic domains which can be contactlessly influenced by an changing magnetic field so that, when a certain field strength is reached, a remagnetization wave, caused by the continuously reversing magnetic domains, occurs in the magnetization portion which runs across the magnetization portion and leads to the generation of the charging impulse.
