摘要： Techniques for estimating a cardiac chamber or vascular pressure based upon impedance are described. A device or system may measure an impedance between at least two electrodes implanted within or proximate to a cardiovascular system. The device or system may estimate a pressure of an element of the cardiovascular system based on a relationship between impedance and volume of the element, and based on a empirical relationship between the volume and the pressure. The device or system may also estimate the dimension of the element based on the impedance-volume relationship, or other characteristics based on the impedance. Because the impedance measurements may be obtained, in some examples, by using electrodes and leads implanted within the cardiovascular system and coupled to an implantable medical device, a practical estimation of a cardiovascular pressure can be obtained on a chronic basis without requiring the use other invasive sensors, such as micronanometer transducers.

摘要： An apparatus for determining a respiration parameter in a medical device in which a pressure sensor senses pressure signals, and a signal processor, coupled to the pressure sensor, receives the sensed pressure signals and generates corresponding sample points. A microprocessor continuously adjusts a breath detection threshold in response to the generated sample points to generate a current adjusted breath detection threshold, compares a current generated sample point to the current adjusted breath detection threshold, suspends the continuous adjusting of the breath detection threshold and sets the breath detection threshold equal to the most current adjusted breath detection threshold generated prior to the suspending, and determines the respiration parameter in response to a comparing of a next generated sample point to the set breath detection threshold.

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.

摘要： An apparatus and method for treating sleep apnea includes control unit in electrical communication with a lead. The control unit is capable of outputting a sleep apnea interruptionpulse to stimulate at least one of a phrenic nerve and a diaphragm. Specifically, an implanted medical device (IMD) such as an implantable cardioverter-defibrillator (ICD) or a pacemaker paces the heart and a mode switch algorithm changes the pacing output to stimulate at least one of a phrenic nerve and diaphragm when sleep apnea is detected by the control unit. The method includes determining if the patient is experiencing sleep apnea and outputting a sleep apnea interruption pulse to the at least one of a phrenic nerve and a diaphragm. The control unit may be incorporated with the IMD. In another embodiment, the control unit may be in wireless communication with the IMD and positioned outside a patient's body.
