    摘要： A system and method for detecting and treating symptoms of early decompensation utilizing a cardiac rhythm management. The system applies an electrical stimulus to the patient's heart at a first set of pacing parameters including a lower rate limit (LRL) setting, and acquires a coronary venous pressure (CVP) signal from a pressure sensor implanted in a coronary vein of the patient. An average coronary venous end diastolic pressure (CV-EDP) value is calculated from the CVP signal. The system monitors the average CV-EDP value over a predetermined interval, and dynamically adjusts the LRL setting responsive to the detection of a first or a second predetermined event based on the average CV-EDP value.

    摘要： A cardiac rhythm management system comprises a medical electrical lead, a pressure sensing element, and an implantable pulse generator. The lead is sized to be advanced through the right atrium and coronary sinus into a coronary vein adjacent to the left ventricle. The lead includes an opening intermediate its proximal and distal ends, and a lumen extending longitudinally within the body in communication with the opening. The pressure sensing element is movably disposed in lead lumen and is dimensioned to extend through the opening in the lead, and includes a flexible, elongated conductive member having a distal end, and a pressure transducer coupled to the distal end of the conductive member. The pulse generator is configured to receive cardiac rhythm signals from the electrode and fluid pressure signals from the pressure transducer.

    摘要： An apparatus and method for reversing ventricular remodeling with electro-stimulatory therapy. A ventricle is paced by delivering one or more stimulatory pulses in a manner such that a stressed region of the myocardium is pre-excited relative to other regions in order to subject the stressed region to a lessened preload and afterload during systole. The unloading of the stressed myocardium over time effects reversal of undesirable ventricular remodeling.

    摘要： An apparatus includes a lead body extending from a proximal end to a distal end and having an intermediate portion therebetween. The lead body includes two or more individually insulated conductors, where a first conductor traverses along less than an entire length of the lead body and a second conductor traverses from the proximal end to the distal end of the lead body. Optionally, the first conductor has a different material than the second conductor, for instance having differing electrical properties and/or differing stiffnesses. A method includes varying the stiffness of a coiled conductor assembly including winding a plurality of conductors to form the coiled conductor assembly, and pulling at least one loop of a first conductor away from the coiled conductor assembly.
