摘要： A method and apparatus for measuring subthreshold defibrillation electrode resistance are disclosed. A known subthreshold current pulse is sourced across the electrodes, the resulting voltage is measured and the electrode resistance is calculated from these values. The calculated electrode resistance may be utilized to adjust the energy level of a defibrillation shock used to treat a detected tachyarrhythmia. In one embodiment the calculated resistance and a predetermined leading edge voltage are used to calculate and adjust the duration of the defibrillation shock. In another embodiment the calculated electrode resistance and a predetermined shock duration are used to adjust the leading edge voltage of the defibrillation shock.

摘要： The present invention, in illustrative embodiments, includes devices for analyzing cardiac signals in an implantable cardiac stimulus system. Within the analysis, a threshold may be defined related to a cardiac event rate. If the cardiac event rate does not exceed the threshold, filtering of captured cardiac signals occurs, including attenuating T-waves. If the cardiac event rate does exceed the threshold, circuitry for analog filtering or programming for digital filtering is bypassed to avoid attenuating low frequency components of the captured cardiac signals.

摘要： Methods of using a template having a template data set and template parameters to provide improved alignment of captured cardiac signal data to a stored template. More particularly, in an illustrative method, a captured cardiac signal is first configured using template parameters for a stored template. Then, once configured, the captured cardiac signal is then compared to the stored template. Other embodiments include implantable cardiac treatment devices including operational circuitry configured to perform the illustrative method. In a further embodiment, more than one stored templates may be used. Each template can have independently constructed parameters, such that a single captured cardiac signal may be configured using first parameters for comparison to a first template, and using second parameters for comparison to a second template.

摘要： High side driver circuitry for a defibrillator circuit employs respective capacitors connected to respective gates of silicon controlled rectifiers serving as high side switches. Applying a voltage pulse to a selected capacitor turns on the associated SCR. Positive turn-on of the high side SCRs is insured by inserting a constant current source into the low side activation current path at start-up.

摘要： A comparator is arranged to compare a series of analog voltage signal samples on a first capacitor with a voltage on a second capacitor which is linearly increased or decreased to equal the sample value. The comparator's single output freezes the count of the counter at counts which are proportional to the voltage of the respective samples. In this manner, analog to digital conversion can be accomplished using a single line between the analog and digital sides of a circuit, thereby reducing parasitic capacitance.
