    摘要： An improved endocardial lead for electrocardial stimulation includes a sleeve that has a face surface. A conductor fitted into the sleeve, such that a distal end of the conductor passes completely through the sleeve, past the face surface, is electrically and mechanically connected to the face surface of the sleeve by mechanical means, e.g. crimping, and/or through the application of heat, e.g. welding or brazing. An electrode is integrated with the sleeve along an outer sleeve surface. A highly reliable, redundant joint is thereby provided between the sleeve and the conductor that secures the conductor against movement and therefore minimizes stress placed on the conductor, preventing fatigue to the conductor at the joint. A sleeve made in accordance with the present invention provides the narrowest and shortest possible conductor/electrode joint to minimize impact on the patient, while at the same time providing an endocardial lead that has excellent electrical properties, mechanical stability, and ease of manufacture, and that may be made from any desired material to thereby take advantage of new and/or improved materials.

    摘要： An implantable cardiac device and method provides for monitoring a progression or regression in heart disease during an extended time period. A sensor generates an electrogram signal representing electrical activity of a patient's heart. From the generated electrogram signal, a processor determines morphology measurements wherein the morphology measurements indicate a progression or regression in the heart disease. The morphology measurements are stored in a memory during the extended period of time. A telemetry circuit transmits the stored morphology measurements to an external receiver for retrieval or display. The morphology measurements may be of electrogram intrinsic activity or evoked response activity characteristics.
