摘要： A method and medical device for detecting a cardiac event that includes sensing a cardiac signal, identifying R-waves in the cardiac signal attendant ventricular depolarizations, determining RR-intervals between successive R-waves in response to the sensed cardiac signal, detecting an atrial tachyarrhythmia based on an analysis of the RR- intervals, iteratively sensing groups of a predetermined number of P- waves attendant atrial depolarizations in response to detecting the atrial tachyarrhythmia, and confirming the atrial tachyarrhythmia based on a P-wave template matching analysis of the iteratively sensed groups of P-waves.

摘要： The invention provides systems to prevent the delivery of anti-tachycardia pacing (ATP) following a defibrillation threshold (DFT) induction at implant. An algorithm that classifies episodes as induced or spontaneous is implemented, thereby enabling the ATP during charging feature to be operable only when spontaneous episodes are detected while temporarily suspending the ATP feature during the delivery of defibrillation shock after induction has been confirmed. Further, a user interface enables users to interact with an implantable medical device (IMD), particularly for setting a defibrillation threshold (DFT) or a 50 Hz burst from a single programmer screen. The user interface includes various functionalities to promote quick user access to parameters that govern diagnosis, therapy and other features of the IMD. A single screen enables the user to complete automatic and/or manual DFT inductions or a 50 Hz burst from a programmer interface while acquiring associated documentation from the same interface.

摘要： The present invention outlines structures and methods for delivering a controllable amount of energy to a patient by automatically compensating for the load impedance detected by an implantable-cardioverter defibrillator (ICD). The invention employs high speed, switching power converter technology for the efficient generation of high energy, arbitrary waveforms. Unlike a linear amplifier, switching power converters deliver high-energy waveforms with an efficiency that is independent of the size and amplitude of the desired waveform. An ICD that uses a switching power converter to deliver the desired energy to the patient stores the energy to be delivered in a storage capacitor. The converter then transforms this energy into an arbitrarily shaped output voltage-controlled or current-controlled waveform by switching the storage capacitor in and out of the output circuit at a high rate of speed. Preferably, the waveform comprises a ramp-type waveform.

摘要： A medical device includes an alert to signal that the amount of stored data is approaching the capacity of the memory in the medical device, and the data must be uploaded to avoid losing the data. A patient perceptible alert may trigger the patient to influence immediate/timely action for data transmission. A silent alert may trigger automatic data transmission, or trigger a medical support network to autonomously conduct transmission of the data.

摘要： In general, the invention provides for adaptive timing of the delivery of cardioversion shocks. In particular, the invention provides for an adaptive cardioversion synchronization delay with respect to a cardiac event, such as a sensed P-wave or R-wave. When cardioversion with a first synchronization delay fails to terminate a tachycardia, for example, cardioversion may be attempted again with a second synchronization delay. A medical device may keep track of whether each synchronization delay is effective in terminating the tachycardia, and may employ a historically effective synchronization delay when applying cardioversion therapy to treat a subsequent tachycardia episode.

摘要： The present invention provides structures and methods for delivering a complex slow-rise defibrillation waveform wherein in lieu of the simple truncation of prior art defibrillation waveforms, when a predetermined amplitude is reached for an ascending waveform (e.g., a ramp waveform), the waveform transitions to an exponential decay portion for a period of time and at the expiration of the period of time, a truncation occurs. In the event that a first complex bi-phasic ramp wave form is implemented, a second opposite polarity waveform may be delivered. Said second waveform is preferably of similar shape to the first waveform, but of a less magnitude amplitude, although the second waveform may comprise a traditional waveform. The implementation and feasibility of the waveforms according to the present invention in an ICD or an AED is relatively simple while providing significant advantages not previously known or used in the prior art.
