摘要： Systems and methods for reducing power consumption in implantable medical devices (IMDs) in which an IMD implantable in an artery monitors blood pressure. A master device monitors a physiological signal, such as respiratory cycle, and instructs the IMD to take blood pressure measurements over a sampling interval, the duration of which is determined by the master device based on the monitored physiological signal. The master device may determine an end-expiration point of the respiratory cycle and send synchronization information to the IMD to further shorten the sampling interval by coinciding the sampling interval with the end expiration point of the respiratory cycle. The IMD may further conserve power by including processing abilities to collect and/or transmit only a subset of data representing the blood pressure signal, for example, systolic, diastolic, and/or mean blood pressure signal values. The blood pressure readings, once taken, may be transferred to the master device.
