SYNCHRONIZING CONTINUOUS SIGNALS AND DISCRETE EVENTS USING IMPLANTABLE DEVICE

摘要

A system comprises an implantable medical device (300) (IMD). The IMD includes at least one electrical input to receive sensed electrical activity of a heart and a sampler circuit coupled to the at least one electrical input. The sampler circuit (340) generates sampled values of the sensed electrical activity. The IMD includes a clock circuit (360) that generates readable values representative of absolute time. The IMD also includes a controller circuit (350) coupled to the sampler (340) circuit and the clock circuit (360). The controller circuit (350) processes the sampled values and generate at least one marker to indicate a detected event related to the electrical activity. The controller circuit (350) also stores a timestamp of absolute time of the detected event with the at least one marker in memory.
