摘要： Techniques are described for detecting ischemia, hypoglycemia or hyperglycemia based on intracardiac electrogram (IEGM) signals. Ischemia is detected based on a shortening of the interval between the QRS complex and the end of a T-wave (QTmax), alone or in combination with a change in ST segment elevation. Alternatively, ischemia is detected based on a change in ST segment elevation combined with minimal change in the interval between the QRS complex and the end of the T-wave (QTend). Hypoglycemia is detected based on a change in ST segment elevation along with a lengthening of either QTmax or QTend. Hyperglycemia is detected based on a change in ST segment elevation along with minimal change in QTmax and in QTend. By exploiting QTmax and QTend in combination with ST segment elevation, changes in ST segment elevation caused by hypo/hyperglycemia can be properly distinguished from changes caused by ischemia.

摘要： Techniques are provided for treating periodic breathing, such as Cheyne-Stokes Respiration, using an implantable medical system. In one technique, diaphragmatic stimulation is delivered during a hyperpnea phase of periodic breathing via electrical stimulation of the phrenic nerves. Diaphragmatic stimulation is synchronized with intrinsic inspiration so as to increase the amplitude of diaphragmatic contraction during inspiration. This tends to decrease intrathoracic pressure leading to occlusion of the respiratory airway. Occlusion reduces actual ventilation during hyperpnea, thus reducing the cyclic blood chemistry imbalance that sustains periodic breathing so as to either mitigate periodic breathing or eliminate it completely. In another technique, respiration is instead inhibited during the hyperpnea phase of periodic breathing by blocking phrenic nerve signals to the extent necessary to reduce ventilation to terminate periodic breathing or at least mitigate its severity. Techniques are also described for controlling the type of therapy applied in response to periodic breathing.
摘要翻译：提供了使用植入式医疗系统治疗周期性呼吸的技术，例如Cheyne-Stokes呼吸。在一种技术中，通过膈神经的电刺激，在定期呼吸的呼吸过度期间传送膈肌刺激。膈肌刺激与固有吸气同步，以增加吸气期间膈肌收缩的幅度。这往往会降低导致呼吸道气道闭塞的胸腔内压力。闭塞减少呼吸过程中的实际通气，从而减少持续周期性呼吸的循环血液化学不平衡，以减轻周期性呼吸或完全消除呼吸。在另一种技术中，通过阻止膈神经信号到减少通气以终止周期性呼吸或至少减轻其严重程度所必需的程度，在呼吸的呼吸过度期间，呼吸反而被抑制。还描述了用于控制响应于周期性呼吸所应用的治疗类型的技术。

摘要： An implantable system applies tiered antitachycardia pacing (ATP) that may be combined with pre-pulsing therapy in order to reduce pain. In one implementation, an exemplary system applies a progression of increasingly potent pacing vectors, progressing in an initial tier from small electrodes inside the heart to later tiers that increasingly use a large electrode surface outside the heart. In the latter tiers, a pre-pulse may be added prior to each ATP pulse to reduce the sensation of pain.

摘要： Techniques are provided for detecting the onset of an episode of apnea/hypopnea substantially in real-time. A moving threshold is generated based on recent respiration cycles and differences are accumulated between amplitudes of new respiration cycles and the moving threshold. Apnea/hypopnea is then detected based upon a comparison of the accumulated differences against a fixed threshold. The technique exploits the fact that many episodes of hypopnea begin with a sharp drop in respiration and many episodes of apnea are preceded by a sharp drop in respiration. By accumulating differences between new respiration amplitudes and a short term moving average, any sharp drop in respiration is thereby promptly detected. In many cases, by the time the amplitudes of individual respiration cycles drop to levels directly indicative of apnea/hypopnea, the episode of apnea/hypopnea will have already been detected based upon the sudden sharp drop in respiration amplitude and therapy will have already been initiated.
