چکیده

conclusions switching ams off may increase biventricular pacing in some patients. case presentation in this case series, we present a combination of far field sensing and automatic mode switching (ams) in six patients. it is found that this combination causes ventricular sensing (vs) episodes with wide qrs and no synchronization. we turn off the ams and alleviate the problem. introduction cardiac resynchronization devices are part of modern heart failure management. after implantation, we analyze and program devices in an attempt to ensure their success. biventricular pacing should be 98% or more for the lowest mortality and best symptom improvement.

Automatic Mode Switch (AMS) Causes Less Synchronization

INTRODUCTION Cardiac resynchronization devices are part of modern heart failure management. After implantation, we analyze and program devices in an attempt to ensure their success. Biventricular pacing should be 98% or more for the lowest mortality and best symptom improvement. CASE PRESENTATION In this case series, we present a combination of far field sensing and automatic mode switching (...

Synchronization of Switch Dynamical Systems

The well known synchronization method of Fujisaka and Yamada is adapted to a particular class of piece wise continuous dynamical systems. We give su¢ cient conditions for the underlying initial value problems, in order to de…ne dynamical systems. For this purpose the Filippov regularization is used, the discontinuous initial value problem being switched into a di¤erential inclusion. A generaliz...

Antibody-membrane switch (AMS) technology for facile cell line development.

Generation of high-productivity cell lines remains a major bottleneck in therapeutic antibody development. Conventional cell line development often depends on gene amplification methodologies using dihydrofolate reductase or glutamine synthetase. Higher productivity is associated with an increased gene copy number. However, lack of selection pressure under the conditions of large-scale manufact...

VHDL-AMS Modeling and Compilation for Parallel Mixed-Mode Simulation

In this paper a survey of recommended VHDLAMS modeling practices for effective parallel simulation is given. Also, a need for extension of VHDL-AMS standard is considered in order to enable the designer to influence parallel simulation performance during the model development. Mixed-mode circuit partitioning algorithms that should be applied during the model compilation are presented.

Control for a synchronization-desynchronization switch.

How to freely enhance or suppress synchronization of networked dynamical systems is of great importance in many disciplines. A unified precise control method for a synchronization-desynchronization switch, called the pull-push control method, is suggested. Namely, synchronization can be achieved when the original systems are desynchronous by pulling (or protecting) one node or a certain subset ...
