摘要： An implantable medical device applies an electric signal to at least a portion of a heart in a subject. A resulting electric signal is collected from the heart and is used together with the applied signal for determining a cardiogenic impedance signal. The impedance signal is processed in order to estimate an isovolumetric contraction time, an isovolumetric relaxation time and an ejection time for a heart cycle. These three time parameters are employed for calculating a Tei-index of the heart. The Tei-index can be used as myocardial performance parameter in heart diagnosis and/or cardiac therapy adjustment.

摘要： An implantable medical device has an impedance processor that determines impedance data reflective of the transvalvular impedance of a heart valve of a heart during a heart cycle. The determined impedance data are processed by a representation processor that estimates diastolic and systolic transvalvular impedance representations. A condition processor determines the presence of any heart valve malfunction, such as valve regurgitation and/or stenosis, of the heart valve based on the estimated diastolic and systolic transvalvular impedance representations.

摘要： A medical implantable lead of the type being adapted to be implanted into a human or animal body and attached with a distal end to an organ inside the body, has a helix of a helical wire in the distal end which is adapted to be screwed into the organ. In addition to the first helix, the lead also has a second helix of a helical wire, the second helix having the same diameter, the same pitch and being intertwined with the helical wire of the first helix and which, upon rotation of the first helix, will be rotated and screwed into the tissue. The first helix is electrically non-conductive whereas the second helix is electrically conductive.

摘要： A lead comprises a mechanical switch at a proximal end of a rotatable shaft. The mechanical switch has a first position to electrically connect a first electric conductor to a second electric conductor for electrically activating a pin and has a second position to electrically connect the first electric conductor to the rotatable shaft for electrically activating a helix. Proper fixation of the helix to an organ is determined by inserting a stylet into the mechanical switch to render the pin electrically active and the helix electrically inactive. Upon determination of proper fixation of the helix to the organ, the stylet is removed from the mechanical switch to render the helix electrically active and the pin electrically inactive.

In another aspect of the invention, at least two different electrode configurations with different noise pick-up areas are used in the measurement. Relations between the noise parameters of the at least two vectors are calculated and compared with reference relations to detect the presence of noise.

摘要： In a system and method for controlling an implantable stimulator capable of producing pacing pulses to be delivered to cardiac tissue, as well as vagal stimulation pulses to be delivered to vagus nerve sites, upon detection of a premature cardiac event, such as a premature ventricular or atrial contraction, a simulated heart rate turbulence (HRT) procedure is applied if the intrinsic heart rate turbulence is weakened or absent. The simulated HRT includes a first phase in which the heart rate is increased, from the existing level, for a number of heart beats, a second phase in which the heart rate is decreased for a number of heart beats, and an optional third phase in which the heart rate is returned to said existing level.

摘要： In an implantable medical device and a method for stimulating a heart of a patient, at least one left atrial pressure (LAP) signal over a cardiac cycle is obtained. The A-wave is identified using the LAP signal and a maximum positive rate of change of the A-wave of the LAP signal is determined. The maximum positive rate of change of the A-wave corresponds to the rate which the pressure in the atrium raises as the atria contraction forces more blood into the ventricle during the very last stage of diastole. Further, AV and/or VV delay is adjusted in response to the maximum positive rate of change of the A-wave, wherein a reduction of the maximum positive rate of change of the A-wave indicates an AV and/or VV delay providing an enhanced hemodynamic performance.

摘要： CRT settings for an implantable medical device are determined by applying pacing pulses to heart chambers of a scheme of different combinations of interchamber delays. A respective width parameter value representing an R or P wave width is determined for each such delay combination based on an ECG representing signal and the width parameter values are employed to estimate a parametric model defining the width parameter as a function of interchamber delays. Candidate interchamber delays that minimize the width parameter are determined from the parametric model and employed to determine optimal CRT settings. The technique provides an efficient way of finding optimal CRT settings when multiple pacing sites are available in a heart chamber.
