  • Patent number: 11654287
    Abstract: The present technology is generally directed to implantable medical device systems configured to provide cardiac resynchronization therapy. In some embodiments, the implantable medical device system comprises a housing, electrodes carried by the housing, a transducer configured to produce input voltage signals in response to ultrasound energy, and a circuit configured to provide, via an electrical pathway, output voltage signals based on the input voltage signals. The circuit comprises a movable switch, and a slew rate detector configured to detect whether a voltage rate of an individual pulse of the input voltage signals exceeds a predetermined threshold voltage rate. The circuit is configured to move the switch to an open position in response to the detected voltage rate exceeding the predetermined threshold voltage rate.
