USE OF A PROGRESSIVE COMPRESSION ENCODING OF PHYSIOLOGIC WAVEFORM DATA IN AN IMPLANTABLE DEVICE TO SUPPORT DISCONTINUING TRANSMISSION OF LOW-VALUE DATA

摘要

An external data retrieval apparatus receives a low resolution version of a physiological signal from an active implantable medical device and determines if the physiological signal represents a clinically significant event. The apparatus provides an indication of such determination to the implantable medical device. If the physiological signal does represent a clinically significant event, the apparatus receives a full download of the physiological signal from the implantable device.
