Heart rhythm status information can be provided to a user, including providing a normal heart rhythm indication if detected electrocardiogram data is indicative of a normal heart rhythm, providing an abnormal heart rhythm indication if detected electrocardiogram data is indicative of an abnormal heart rhythm. Further, a current heart rhythm can be recorded, including recording the current heart rhythm in response to the provided abnormal heart rhythm indication if an abnormal heart rhythm indication is provided in response to the first query command, and recording the current heart rhythm in response to a second patient-initiated query command from the user-interface device following a normal heart rhythm indication in response to the first query command.

Method of patient initiated electro-cardiogram storage, status query and therapy activation

The present invention relates to a wireless handheld device that is configured to communicate with an implanted device using inductive telemetry. The handheld device is preferably battery operated and includes a battery powered controller and a battery powered inductive coil. The inductive coil is configured to communicate with an inductive coil of the implanted device using inductive telemetry. The handheld device may include one battery voltage source that powers both the controller and the inductive coil, or multiple battery voltage sources to power the controller and inductive coil separately. In a single battery voltage source embodiment, the voltage may be amplified or reduced to meet the power needs of the controller and inductive coil. In a multiple battery voltage source embodiment, the voltage sources may be combined to increase the power output requirements of the inductive coil.

Telemetry for a battery operated device

A system including a communication circuit and a microprocessor operable to execute instruction code associated with at least a first operating system and a second operating system. The system also includes a volatile system memory to store executable code, a nonvolatile memory to store executable startup code, and nonvolatile image storage to store at least one captured state image. The captured state image includes an image of system memory in a captured state associated with a non-executing operating system. The system further includes a system transition routine to transition between the executing operating system and the non-executing operating system when an application to be run on the microprocessor requires the non-executing operating system. The system transition routine converts content of volatile memory and microprocessor registers to a captured state in accordance with the non-executing operating system captured state image stored in the nonvolatile image storage.

Fast initialization of medical device system having multiple operating systems

A handheld cardiac rhythm management device for use by a patient to request status information from an implantable pulse generating device and to request that the pulse generating device provide a rhythm altering shock to the patient's heart. The device includes a plurality of deadfront status indicator lamps on a front of a case that are visible to the patient when the controller is held in the patient's hand. The device also includes buttons on the front of the case and a telemetry circuit for bi-directional communication with the implantable pulse generating device.

A system and method for restoring a microprocessor-based system to a previously booted target state in which an image of memory and the processor registers in the previously booted state is saved and stored in a storage device. A restore routine executing in ROM retrieves the image from the storage device and restores the system memory and processor registers to the target state. An operating system return routine then returns control of the system to the operating system software. In an exemplary implementation, a system in accordance with the invention is incorporated into a microprocessor-based external programmer for a cardiac rhythm management device in order to allow quick starting of the programmer from a powered down condition without going through a time consuming boot process.

A system and method for restoring a microprocessor-based system to a previously booted target state in which an image of memory and the processor registers in the previously booted state is saved and stored in a storage device. A restore routine executing in ROM retreives the image from the storage device and restores the system memory and processor registers to the target state. A operating system return routine then returns control of the system to the operating system software. In an exemplary implementation, a system in accordance with the invention is incorporated into a microprocessor-based external programmer for a cardiac rhythm management device in order to allow quick starting of the programmer from a powered down condition without going through a time consuming boot process.
