Abstract: The present disclosure provides systems and methods for automatically determining pace and sense configurations for an implantable cardiac device. A method of operating an implantable cardiac device includes automatically determining, during a detection phase, a pace and sense configuration for the implantable cardiac device based on a plurality of first impedance measurements. The method further includes confirming, during a confirmation phase, the pace and sense configuration based on a plurality of second impedance measurements, and operating the implantable cardiac device in accordance with the pace and sense configuration.

Abstract: An electric water pump includes a housing, a propelling mechanism disposed in the housing, and a driving mechanism for driving a driving shaft of the propelling mechanism. The driving shaft has a fluid passage in fluid communication with an impeller chamber and a cooling chamber in the housing. The propelling mechanism further includes a spiral rod disposed in the fluid passage and co-rotatable with the driving shaft, and an impeller disposed in the impeller chamber. During operation of the propelling mechanism, the impeller drives flow of a fluid, and the spiral rod co-rotates with the driving shaft to change the rate of the fluid flowing through the driving shaft.
