    摘要: An implantable cardiac device is disclosed having a converter that provides a digital electrocardiogram signal to a controller which is stored in memory or transmitted via the telemetry circuit in an improved compressed fashion. The improved compression scheme comprises sampling the electrogram signal, transmitting the starting value in an uncompressed format followed by a plurality of delta signals in a compressed format. The delta signals may be determined by subtracting successive signals or by subtracting a predicted value from the current value. In either case, the delta signal is then transmitted in a truncated number of bits, e.g., 2 or 4 bits. When the delta signal is too large to be represented in the compressed number of bits, the controller then provides an indicator signal followed by the delta signal in the uncompressed format. In addition, whenever successive delta signals are below a minimum threshold (e.g., zero), they may be compressed into a count.

    摘要: A cardiac event and arrhythmia detection system and method detects arrhythmic cardiac activity or other information from an electrogram signal of a heart. The system senses the electrogram signal through an electrogram lead, preliminarily processes the signal, and converts it to a plurality of discrete digital signals, each of which represents the magnitude of the electrogram signal at a prescribed sample time. The discrete digital signals are applied to both a cardiac event detector and a morphology detector. The morphology detector detects selected changes in the morphology (shape) of the electrogram signal, wherein such changes automatically control the sensitivity (gain and/or threshold) used to detect cardiac events. The occurrence of a prescribed amount of change in the detected morphology over time indicates the occurrence of a prescribed arrhythmic cardiac condition.

    摘要: Systems for treating a movement disorder include a system control unit configured to be implanted at least partially within a patient and to generate at least one stimulus in accordance with one or more stimulation parameters adjusted to treat the movement disorder. The systems further include a programmable memory unit in communication with the system control unit and programmed to store the one or more stimulation parameters to at least partially define the stimulus such that the stimulus is configured to treat the movement disorder. A means for applying the stimulus to one or more stimulation sites within the patient is operably connected to the system control unit.
