    • Methods and apparatuses are provided for assisting with the diagnosis, monitoring, and/or treatment of patients that are suffering from asymptomatic heart failure or may be susceptible to asymptomatic heart failure. The methods and apparatuses can be implemented with implantable devices. In certain implementations, a method is provided which includes sensing muscle sympathetic nerve activity using at least one nerve sensing electrode that is in electrical contact with a patient's efferent muscle-nerve structure, acquiring a muscle sympathetic nerve activity signal from the sensed nerve activity using a nerve activity sensing circuit operatively coupled to the nerve sensing electrode, and analyzing the nerve activity signal for changes in nerve burst activity indicative of the presence and/or severity of asymptomatic heart failure.

    • An implantable cardiac stimulating device employs an automatic defibrillation threshold tracking process that uses a measured pacing stimulation threshold to estimate the patient's defibrillation threshold on a dynamic, ongoing basis, using changes in the defibrillation threshold to re-calculate new defibrillation parameters (e.g., energy settings) on a periodic basis as a patient's heart changes over time. The defibrillation threshold estimation formula may involve a variety of variables, such as, for example, the patient's age and/or gender, and may include a selected safety margin. New defibrillation parameters are loaded into the appropriate locations of the device's memory, replacing the prior parameters, and are thereafter available for use by the device for defibrillation therapy. The defibrillation threshold tracking technique may be used in an external device, such as a programmer or external cardiac stimulation device.
    • 可植入心脏刺激装置采用自动除颤阈值跟踪过程,该过程使用测量的起搏刺激阈值在动态持续的基础上使用除颤阈值的变化来估计患者的除颤阈值,以重新计算新的除颤参数(例如能量设定 )作为患者的心脏随着时间的推移而定期进行。 除颤阈值估计公式可以涉及各种变量,例如患者的年龄和/或性别,并且可以包括所选择的安全裕度。 新的除颤参数被加载到设备的存储器的适当位置,替换了先前的参数,然后可用于设备用于除颤疗法。 除颤阈值跟踪技术可以用在诸如编程器或外部心脏刺激装置的外部装置中。

    • A method and apparatus for generating biphasic waveforms uses an implantable cardioverter defibrillator (ICD) system having a phase transition enhancing capacitor system in addition to the capacitor system(s) which deliver the first and second phase of the biphasic countershock. Preferably, the ICD system has at least three capacitor systems and a capacitor switching network. The three capacitor systems include two primary capacitor systems and a third high voltage phase transition enhancing capacitor system having a time constant shorter than the time constant of the two primary capacitor systems. A first phase of the biphasic waveform preferably is produced by configuring the two primary capacitor systems to selectively discharge first in a parallel combination, and then in a series combination. The second phase of the biphasic waveform preferably is produced by reconfiguring the two primary capacitor systems to discharge in a parallel combination with reversed polarity. The phase transition enhancing capacitor system is selectively switched into the discharge of the biphasic waveform so as to effectively increase the voltage differential seen by the heart during the transition between the first and second phases of the biphasic waveform.

    • Aspects of the invention are directed to advanced monitoring and control of medium voltage therapy (MVT) in implantable and external devices. Apparatus and methods are disclosed that facilitate dynamic adjustment of MVT parameter values in response to new and changing circumstances such as the patient's condition before, during, and after administration of MVT. Administration of MVT is automatically and dynamically adjusted to achieve specific treatment or life-support objectives, such as prolongation of the body's ability to endure and respond to MVT, specifically addressing the type of arrhythmia or other pathologic state of the patient with targeted treatment, a tiered-intensity MVT treatment strategy, and supporting patients in non life-critical conditions where the heart may nevertheless benefit from a certain level of assistance.
