Abstract

A system for providing temporary therapy, such as cardiac resynchronization therapy, to a patient suffering a decompensation event. The system can include a device having an external module for generating electrical stimuli, a first lead coupled to the module and implanted into an atrial region of a patient'"'"'s heart, and a second lead coupled to the module and implanted into a ventricular region of the patient'"'"'s heart. The device can also include a storage module coupled to the external module to store data associated with physiological data measured by the device. The external module is configured to temporarily generate electrical stimuli that are delivered by at least one of the first and second leads to provide therapy cardiac resynchronization therapy to the heart. A network can be coupled to the device to allow data stored in the device to be downloaded through the network to a central repository.
