Abstract: Techniques for using multiple physiological parameters to provide an early warning for worsening heart failure are described. A medical device monitors a primary diagnostic parameter that is indicative of worsening heart failure, such as intrathoracic impedance or pressure, and one or more secondary diagnostic parameters. The medical device detects worsening heart failure in the patient based on the primary diagnostic parameter when an index that is changed over time based on the primary diagnostic parameter value is outside a range of values, termed the threshold zone. When the index is within the threshold zone, the medical device detects worsening heart failure in the patient based on the one or more secondary diagnostic parameters. Upon detecting worsening heart failure, the medical device may, for example, provide an alert that enables the patient to seek medical attention before experiencing a heart failure event.

Abstract translation: 描述了使用多种生理参数为恶化心力衰竭提供早期预警的技术。 医疗设备监测指示心脏衰竭恶化的主要诊断参数，例如胸内阻抗或压力，以及一个或多个次要诊断参数。 当基于主要诊断参数值随时间改变的索引在称为阈值区域的值的范围之外时，医疗装置基于主要诊断参数来检测患者的心脏衰竭的恶化。 当索引在阈值区域内时，医疗装置基于一个或多个次要诊断参数来检测患者心脏衰竭的恶化。 在检测到心脏衰竭恶化时，医疗装置可以例如提供使患者能够在经历心力衰竭事件之前寻求医疗护理的警报。

Abstract: A system and method is provided to measure intrathoracic complex impedance and to identify and indicate disease conditions based on the impedance measurements. Multiple impedance vectors may be taken into account, and an optimal vector may be selected to provide the most useful impedance measurement for the identification and indication of disease conditions.
