摘要： An implantable medical device performs impedance measurement and demodulation, such as for obtaining lead impedance measurements, or thoracic impedance measurements, such as for extracting respiration, cardiac stroke, or fluid status information. A 4-point FIR filter demodulator can be used to demodulate a two-phase current excitation waveform. The demodulator can also be used to measure noise for triggering a noise response. Among other things, an increased excitation current level can be used when noise is deemed to be present.

摘要： A filtered feedthrough assembly for an implantable medical device comprises a ferrule, an electrical insulator coupled to the ferrule by a connection element, a plurality of feedthrough conductors extending through the electrical insulator, a printed circuit board (PCB), and plurality of capacitors. The PCB is coupled to the ferrule or the electrical insulator, and includes one or more ground layers and a plurality of vias. The connection element is electrically coupled to the ground layer through the vias. The capacitor has a ground terminal electrically coupled to the ground layer through at least one of the vias, and a conductor terminal electrically coupled to the feedthrough conductor.

摘要： During auto-threshold, autocapture, or other evoked response sensing, post-pace artifact is reduced by using a smaller coupling capacitor value than what is used when not in such an evoked response sensing configuration. This can be accomplished by borrowing another capacitor for use as the coupling capacitor. The borrowed capacitor can be a backup pacing capacitor from the same or a different pacing channel. The borrowed capacitor can also be a coupling capacitor from a different pacing channel.
