Abstract: 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.

Abstract: Processes and systems are provided for monitoring and blending a first stream and a second stream to produce a third stream of desired compositional characteristics. The processes and systems are found to be particularly useful for the blending of two or more hydrocarbon streams to economically produce a targeted hydrocarbon product stream meeting prescribed compositional specifications. Specifically, the processes and systems are found to be especially useful to blend a propane containing stream, having a vapor pressure lower than the vapor pressure of a targeted vapor pressure for a propane product, with an ethane containing stream. The blending processes and systems allow for production of an “on-spec” propane product stream while at the same time maximizing the value of the ethane stream. The processes and systems may incorporate continuous real-time analysis and flow control of the various streams to effectuate precise control the blending processes.

Abstract: The implantable cardiac treatment system of the present invention is capable of choosing the most appropriate electrode vector to sense within a particular patient. In certain embodiments, the implantable cardiac treatment system determines the most appropriate electrode vector for continuous sensing based on which electrode vector results in the greatest signal amplitude, or some other useful metric such as signal-to-noise ratio (SNR). The electrode vector possessing the highest quality as measured using the metric is then set as the default electrode vector for sensing. Additionally, in certain embodiments of the present invention, a next alternative electrode vector is selected based on being generally orthogonal to the default electrode vector. In yet other embodiments of the present invention, the next alternative electrode vector is selected based on possessing the next highest quality metric after the default electrode vector.

Abstract: In a subcutaneous implantable cardioverter/defibrillator, cardiac arrhythmias are detected to determine necessary therapeutic action. Cardiac signal information is sensed from far field electrodes implanted in a patient. The sensed cardiac signal information is then amplified and filtered. Parameters such as rate, QRS pulse width, cardiac QRS slew rate, amplitude and stability measures of these parameters from the filtered cardiac signal information are measured, processed and integrated to determine if the cardioverter/defibrillator needs to initiate therapeutic action.
