摘要： Medical devices and methods are used to treat cardiac dysfunction conditions which involve delivery of stimulation pulses in cardiac refractory periods in order to modulate an effective refractory period (ERP). Such devices and methods may be used in conjunction with or in place of other therapies, including increased cardiac contractility (ICC) therapy, post extrasystolic potentiation (PESP) therapy, and other therapies to achieve increased heart contractility, provide a safer and more effective regimen for the corresponding stimulation therapies, and reduce the risk of inducing an arrhythmia.

摘要： The present invention relates to the secure delivery of an extra-systolic stimulation (ESS) therapy to treat cardiac dysfunction that employs atrial and/or ventricular extra-systoles via pacing-like stimulation of the heart. These extra-systoles must be timed correctly to achieve beneficial effects on myocardial mechanics (benefit) while maintaining an extremely low level of risk of arrhythmia induction and excellent ICD-like arrhythmia sensing and detection (security). Further experience with ESS has led to improved implementation methods that depend on better blanking, ESS stimulation timing (of an “extra-systolic interval” or ESI), and ESS therapy delivery options and guidance. These methods may be employed individually or in combinations in an external or implantable ESS therapy delivery device.

摘要： Techniques for delivering ESS to a heart of a patient are disclosed. An implantable medical device delivers ESS stimulation, and in some embodiments pacing stimulation, to a chamber of the heart via a first electrode set. The implantable medical device senses electrical activity within the chamber via a second set of electrodes. In some embodiments, the implantable medical device is able to apply a shorter blanking interval than is typical in the pacing art to a sense amplifier coupled to the second set of electrodes, allowing the implantable medical device to better detect arrhythmias and evoked responses. A variety of electrodes may be used in conjunction with the present invention; including without limitation, tip, ring, coil, can-based, endocardial, epicardial, pericardial, cardiac vein-based, subcutaneous, and/or surface electrodes.

摘要： A method of operating a cardiac pacing device that optimizes the mechanical heart rate using coordinated potentiation therapy while maximizing the opportunity for intrinsic AV conduction to occur. The method may include adjusting the timing of extra stimulus intervals during coupled or paired pacing to promote AV conduction and to effect changes in rate according to certain embodiments of the invention. Other embodiments may include adjusting the atrial pacing rate to achieve a desired target rate consistent with AV conduction. A mode switch to a dual-chamber pacing mode may be provided according to certain embodiments of the invention to ensure a ventricular rate that meets or exceeds a minimum mechanical rate.

摘要： An implantable medical device evaluates ventricular synchrony by determining a phase angle between at least two sensor signals that reflect mechanical contraction of the ventricles. In exemplary embodiments, two intracardiac impedance signals associated with the right and left ventricles, respectively, with two points within either of the left and right ventricles, or with both the left and right ventricles relative to a reference point, are processed. In such embodiments, fundamental frequency phases of each of the impedance signals may be compared to determine the phase angle between the signals. In some embodiments, the signals are used to dynamically adjust one or more timing intervals, such as a V-V timing interval, for delivery of cardiac resynchronization therapy (CRT) pacing. In such embodiments, the one or more timing intervals are periodically adjusted to reduce or possibly eliminate ventricular dysynchrony as indicated by the phase angle between the sensor signals.
