Relay circuit for cardiac pacemaker implant

摘要

A relay circuit for a cardiac pacemaker having a stimulator implanted in a user. A first detector and a relay is involved for detecting and amplifying a cardiac wave, the first detector being capable of relaying the cardiac wave as a signal; a second detector and a relay is provided for detecting a stimulus signal of the stimulator of the pacemaker, the second detector being capable of relaying the stimulus signal; a cycle-to-cycle control receives signals from the first and second detectors for constructing a cycle-to-cycle wave signal of the cardiac and stimulus signals in accordance with a cardiac or physiological T wave and a stimulus R wave representation respectively of an electrocardiogram; a wave absence detector for detecting the absence of the cardiac wave or the stimulus wave in the cycle-to-cycle control, the wave absence detector being capable of relaying a wave absence signal; a receiver for receiving the wave absence signal and including a converter for translating the wave absence signal into a counteraction signal; and a counteractor for receiving the counteraction signal, including the provision of a signal for signaling a counteraction.
