    摘要： Methods and systems for performing capture threshold tests are described. During an initialization procedure a capture detection interval and capture detection threshold are determined based on peak values of cardiac signals sensed following the supracapture threshold initialization pulses. Following initialization, a plurality of pacing pulses to the atrium are delivered and the peak values of the cardiac signals sensed following each of the plurality of pacing pulses are determined. The peak values are compared to the pacing artifact threshold and the capture detection threshold. A timing of each of the peak values is compared to the capture detection interval. For each pacing pulse, discrimination between a captured response, a noncaptured response, and a fusion response is based on the peak value and timing comparisons.

    摘要： Methods and systems for classifying cardiac responses to pacing stimulation and/or preventing retrograde cardiac conduction are described. Following delivery of a pacing pulse to an atrium of the patient's heart during a cardiac cycle, the system senses in the atrium for a retrograde P-wave. The system classifies the atrial response to the pacing pulse based on detection of the retrograde P-wave. The system may also sense for an atrial evoked response and utilize the atrial evoked response in classifying the cardiac pacing response.

    摘要： The present invention provides a process for production of an anticancer taxoid brevifoliol of the formula I from plants belonging to the genus Taxus by first extracting the dried and pulverized leaves of the plant with an alcohol preferably at a temperature in the range of 20-40° C. and then. concentrating the solvent to obtain an alcoholic extract. The alcoholic extract obtained is then adsorbed with an adsorbent and the resulting adsorbed material is then dried at a temperature ranging from 20-50° C. for 4-48 hours. The dried adsorbed material is then extracted with a combination of an aliphatic solvent and a chlorinated solvent successively and concentrated to obtain a residue. The residue is subjected to gross fractionation using column chromatography such as silica gel, florosil and silicic acid followed by chromatography with a suitable adsorbent to get brevifoliol.
