摘要： A method and system are presented for use in monitoring a subject's heart conditions such as ejection fraction and cardiac synchrony. For determination of the ejection fraction, ECG measured data is processed. This ECG measured data comprises a first measured data portion indicative of a first time profile of an electrical signal measured on a planar pair of electrodes applied on a patient during a measurement session and a second measured data portion indicative a second time profile of an electrical signal measured on a diagonal pair of electrodes applied to said patient during said measurement session. The processing comprises comparing the first and second data portions to identify a time shift between a predetermined event in the first and second time profiles. For the determination of heart synchrony, first and second measured data portions corresponding to respectively an ECG measurement and an acoustic measurement both obtained from a patient during the same measurement session of a duration including at least two cardiovascular cycles, are processed. Such processing comprises identifying predetermined first and second events in each of said at least two cycles in the first and second measured data portions, respectively, determining a relation between the first and second events for each of the at least two cycles, determining a degree of fluctuation of said relation in the at least two cycles.

摘要： The invention provides a method and system for analyzing body sounds from one or more body organs. An array of transducers is fixed to the body surface over the organs from which body sounds are to be recorded. Analysis of the recorded sound signals includes dividing each signal into one or more time intervals and calculating an average of the signal in each time interval. A difference signal is calculated for each interval, where the difference signal is the difference of the recorded signal in the interval and the interval average. An energy assessment signal is then calculated in each interval using the difference signal. In an embodiment, the energy assessment signal is a standard deviation signal. The subject matter may be used to record and analyze cardiovascular sounds for diagnosing abnormal cardiovascular function, or for calculating an ejection fraction.

摘要： A method and system for regional assessment in two or more regions of an individual's lungs. The system includes a plurality of transducers configured to be fixed over the thorax. Each transducer generates a signal P(xi,t) indicative of pressure waves at the location of the transducer. The transducers are divided into subsets, where each subset overlies a specific region of the two or more regions. An energy assessment signal is calculated from each of the signals P(xi,t). For each region, an assessment of the region is calculated from the energy assessment signals of the region.

摘要： An apparatus for measuring intracranial pressure constituted of a transmitter arranged to transmit a first acoustic signal through a first cranial point, a receiver arranged to receive a second acoustic signal from a second cranial point and a control circuitry. The control circuitry is arranged to extract from the detected second acoustic signal a first set of frequency components associated with the transmitted first acoustic signal and extract from the detected second acoustic signal a second set of frequency components associated with intracranial processes. The control circuitry is further arranged to determine intracranial pressure responsive to the extracted first set of frequency components and the extracted second set of frequency components.
