    摘要: An implantable heart analyzing device has a housing and a control circuit located within said housing. The control circuit generates an output signal adapted to actuate an activator, which is able to make a wall of the heart deflect or vibrate. The control circuit also communicates with a sensor, which can be identical with the activator, with which the movement of the heart wall can be sensed. The control circuit executes a procedure that involves the generation of an output signal and sensing a corresponding sensor signal, and to be able to derive information concerning the tension of the heart wall. An implantable heart analyzing includes the aforementioned heart analyzing device, as well as the activator and the sensor. The heart analyzing device and the system implement a method that results in generation of the aforementioned information concerning the tension of the heart wall.

    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 late potential detecting system has an implantable medical device connected to at least one cardiac lead having implantable electrodes positioned at different sites of a ventricle myocardium. A sampling unit of the implantable medical device records electrogram samples for the different implantable electrodes to get different sample sets. The electrogram samples of the sample sets are time synchronized and magnitude potential representations of the potential data of the electrogram samples are determined. The magnitude potential representations of the time synchronized electrogram samples are then co-processed and used for determining a parameter that is indicative of any late potentials of the monitored ventricle.
