Abstract: This document discusses, among other things, a system including an implantable medical device. The implantable medical device includes a control circuit and a motion sensing device.

Abstract: A cardiac rhythm management system recognizes patterns of interval durations, distinguishing between events in different heart chambers even though signals associated with those different heart chambers are processed using a commonly shared sensing circuit. A therapy delivery algorithm ignores intervals between cardiac events occurring in different heart chambers when determining a cardiac rate upon which the delivery of therapy is based. This reduces the risk of inappropriate delivery of therapy to the patient. Delayed conduction left ventricular beats are not erroneously recognized as a subsequent right ventricular beat, preventing such short intervals from inappropriately triggering a defibrillation countershock.

Abstract: A device and method for implementing a bradycardia pacing mode are disclosed which is mostly hardware-based but still allows the flexibility for making major changes in brady behavior normally found only in firmware-based implementations. The brady behavior of the device is encapsulated by a table in an area of RAM referred to as brady RAM, and the brady behavior can be changed by re-loading the brady RAM with a different table.

In one exemplary embodiment, the present invention provides for centralized validation and maintenance of medical information derived from a patient visit. Thus, for example, a patient may visit his/her physician and during that visit the physician may read information from an implantable medical device associated with the patient, make other objective measurements of the patient, and record various subjective information about the patient. All of this information can be uploaded, validated and maintained on a variably accessible system. In some embodiments the validation process can occur in a single user communication session, or otherwise in a near real-time process.

Abstract: A cardiac rhythm management system having a plurality of timers and programming adapted to receive a status array. The status array is based on the status of each timer of the plurality of timers and includes intrinsic activity detection for each pace sense site. The plurality of timers are initiated concurrent with a detected event or condition. The status array is masked according to an enable array and an interrupt signal is generated based on selected bit transitions of the status array. The interrupt signal initiates a predetermined therapy or function based on the status array. A FIFO buffer preserves the order of senses and paces for further processing. The predetermined therapy or function includes determining a mode of operation of the system.

Abstract: An implantable medical tissue stimulating device is designed to capture fault history relating to error events in a manner that allows subsequent analysis of operational performance prior to, during and subsequent to the occurrence of a detected error. Physiologic and operational data are fed through a buffer capable of temporarily storing such data over a predetermined interval. When a fault condition is detected, a trigger signal is generated a predetermined time following the occurrence of the fault condition and, upon generation of the trigger signal, the contents of the buffer are stored away in a RAM memory for subsequent read-out.

Abstract: A cardiac rhythm management system recognizes patterns of interval durations, distinguishing between events in different heart chambers even though signals associated with those different heart chambers are processed using a commonly shared sensing circuit. A therapy delivery algorithm ignores intervals between cardiac events occurring in different heart chambers when determining a cardiac rate upon which the delivery of therapy is based. This reduces the risk of inappropriate delivery of therapy to the patient. Delayed conduction left ventricular beats are not erroneously recognized as a subsequent right ventricular beat, preventing such short intervals from inappropriately triggering a defibrillation countershock. The system detects cardiac events, obtains a current interval between a current cardiac event and a previous cardiac event, and classifies the current interval into at least first and second categories, based on a duration of the current interval.
