    • A method of data management for optimizing the patient outcome from the provision of cardiac resynchronization therapy (CRT) is described. A regression equation is constructed using 3 data points on a plot of AV delay vs. HR. The x-axis consist of the three points consist of resting HR, HR at the optimal AV delay value during light exercise, and the upper tracking or paced HR. The y-values associated with the three points consist of the AV delay values computed using an equation for ventricular filling time and the optimally determined AV delay value. Also described is a process for determining the sensed to paced AV delay offset. The combined processes yield 4 (the three constant values in the polynomial regression equation Y=b2X2+b1X+a and the sensed to paced AV delay offset) which can be stored on the patient's pacemaker for determining dynamically the AV delay value which is physiologically fine-tuned for each patient from resting HR to the upper tracking or paced HR. In combination with visual observation and computer-assisted ranking of the dependent variables, a physician can utilize the resulting information to render decisions on the optimal choice of the programming biventricular pacemakers/ICDs and DDDR pacemakers for individual patients.
    • 描述了一种用于从提供心脏再同步治疗(CRT)中优化患者结果的数据管理方法。 在AV延迟与HR的图上使用3个数据点构建回归方程。 x轴由休息HR,轻度运动期间最佳AV延迟值处的HR以及上跟踪或起搏HR组成的三个点组成。 与三点相关联的y值包括使用用于心室充盈时间的方程和最佳确定的AV延迟值计算的AV延迟值。 还描述了一种用于确定感测到的起搏AV延迟偏移的过程。 组合过程产生4(多项式回归方程中的三个常数值Y = b2X2 + b1X + a和感测到的AV延迟偏移),其可以存储在患者起搏器上以动态地确定生理学上良好的AV延迟值 将每个患者的休息时间从静息HR调整到上部跟踪或节奏的HR。 结合视觉观察和计算机辅助排列的因变量,医师可以利用所得到的信息来对个体患者的双心室起搏器/ ICD和DDDR起搏器编程的最佳选择作出决定。

    • A cardiopulmonary exercise system for real-time, breath-by-breath acquisition, analysis, display and printing of an individual's physiologic parameters. A microprocessor based waveform analyzer receives inputs from a CO.sub.2 analyzer, an ECG monitor, an O.sub.2 analyzer, and a pneumotachograph, and, optionally, can also connect a cycle ergometer, a treadmill, a cardiac stress system, and an ear oximeter. The waveform analyzer provides output data to a host central processor unit to which a CRT display, a graphics copier or hard-copy printer may be connected for providing medical data for assessment of an individual's heart and lungs, on a real-time basis whereby the level of fitness or underlying organic defects which may effect the cardiopulmonary system can be determined. The pneumotachograph, CO.sub.2 analyzer and O.sub.2 analyzer and ECG monitor provide analog signals representing flow, CO.sub.2 and O.sub.2 levels in expired air as well as heart rate. The waveform analyzer, under control of its dedicated microprocessor, performs an A/D conversion with the microprocessor also being used to calculate the tidal volume (V.sub.T), minute ventilation (V.sub.E), breathing frequency (f.sub.B), cardiac frequency (f.sub.C), inspiratory time (T.sub.I) and total time (T.sub.TOT) of last breath, fraction of CO.sub.2 in inspired gas (F.sub.ICO.sbsb.2) and fraction of O.sub.2 in inspired gas (F.sub.IO.sbsb.2), peak CO.sub.2 and O.sub.2 (F.sub.ETCO.sbsb.2 and F.sub.ETO.sbsb.2), and expired volumes of CO.sub.2 and O.sub.2 (VCO.sub.2 and VO.sub.2) breath-by-breath. The system of the preferred embodiment analyzes the individual's expirate at a sample rate of one hundred samples per second per channel with twelve bit resolution.
