Summary:Techniques for estimating the remaining life of a power supply of an implantable medical device (IMD) using a wireless telemetry rate of the IMD are disclosed. For example, the IMD sets a timer indicating a remaining power capacity of the power supply up to a recommended replacement time (RRT) threshold. The IMD determines power consumption of the IMD due to telemetry, and updates the timer indicating the remaining power capacity of the power source based on the power consumption of the IMD due to telemetry. The IMD determines that the power supply has reached the RRT threshold based on expiration of the timer indicating the remaining power capacity of the power supply. In some examples, the IMD may output an indication to an external device that the power supply has reached the RRT threshold and for display to a user. 本发明公开了使用植入式医疗装置(IMD)的无线遥测速率来估计所述IMD的电源的剩余寿命的技术。例如，所述IMD设置指示所述电源的直到推荐更换时间(RRT)阈值的剩余功率容量的定时器。所述IMD确定所述IMD的由于遥测而导致的功率消耗，并且基于所述IMD的由于遥测而导致的所述功率消耗来更新指示所述电源的所述剩余功率容量的所述定时器。所述IMD基于指示所述电源的所述剩余功率容量的所述定时
