A relationship is established between a voltage of a measurement electrode and a solid-liquid suspension state to avoid the problems of strong subjectivity and large deviation appearing in existing critical suspension speed determination based on empirical formulas and human eye observation. An electrode voltage ratio is taken as a determination criterion, which is only related to a spatial density of solid particles in a liquid phase.

Abstract: A cardiac pacing system and a pacemaker fixation device are disclosed. The pacemaker fixation device includes a ring-shaped stent and at least one contractible member. The ring-shaped stent is configured to load a leadless pacemaker and easily fix it at a target site in a patient's body reliably without dislodgement. A connecting element in the contractible member can be reliably connected to an external mechanism, thus facilitating retrieval and removal of the cardiac pacing system with an increased success rate. During implantation, the contractible member can be adapted by operating the external mechanism to adjust the pacing location for the leadless pacemaker, thus allowing the operator to easily determine the best pacing location that can result in enhanced pacing performance of the leadless pacemaker. Further, the leadless pacemaker may be fixed in the atrium in order to pace the atrium, thus reducing non-physiological pacing with atrioventricular desynchronization.
