摘要： A medical imaging system adaptively acquires anatomical images. The system includes a synchronization processor for providing a heart rate related synchronization signal derived from a patient cardiac function blood flow related parameter. The synchronization signal enables adaptive variation in timing of acquisition within successive heart cycles of each individual image frame of multiple sequential image frames. An image acquisition device initiates acquisition of anatomical images of a portion of patient anatomy in response to the synchronization signal. A display processor presents images, acquired by the acquisition device and synchronized with the synchronization signal, to a user on a reproduction device. The image acquisition device adaptively selects image pixel resolution of individual image frames of the multiple sequential image frames in response to data identifying a heart cycle segment so that successively acquired image frames have different image pixel resolution within a single heart cycle.

摘要： A system determines measured patient values for use in clinical calculations using an electronic form including, a first area including data fields for presenting values of the parameters associated with a first part of a cardiac catheterization study of a patient and a second area including data fields for presenting values of the parameters associated with a different second part of a cardiac catheterization study of the patient. A user interface enables a user to copy at least one of the parameters comprising a measured value from the first area to the second area as a substitute value eliminating a need for a re-measurement of the value. A calculation processor automatically calculates a cardiac flow value for incorporation in the second area in response to the measured value being copied into the second area.

摘要： A system provides early prediction of heart tissue malfunction and electrophysiological pathology by determining anatomical tissue impedance characteristics for use in medical patient monitoring and treatment decision making. At least one repository of data indicates multiple predetermined expected impedance value ranges for corresponding multiple impedance measurements taken at multiple particular different sites of at least one anatomical organ. An impedance measurement processor automatically determines whether multiple measured impedance values taken at multiple particular different sites of an anatomical organ using an invasive catheter are within corresponding multiple predetermined expected impedance value ranges derived from the at least one repository. An output processor automatically communicates data comprising at least one message to a destination. The at least one message includes data indicating whether the multiple measured impedance values taken at the multiple particular different sites of the anatomical organ are within the corresponding multiple predetermined expected impedance value ranges.

摘要： A system for respiration or cardiac condition characterization and abnormality detection includes an interface that receives data representing a signal indicating concentration of carbon dioxide in patient gases over multiple signal cycles. A signal processor uses the received data in determining multiple amplitude related characteristic values. A comparator compares at least one of the amplitude related characteristic values or a value derived from the amplitude related characteristic values, with a threshold value to provide a comparison indicator. A patient monitor in response to the comparison indicator indicating an amplitude related characteristic value or a value derived from the amplitude related characteristic values, exceeds the threshold value, generates an alert message associated with the threshold.

摘要： A system and method are disclosed for utilizing a single integrated EP/ablation catheter to treat cardiac arrhythmias. The disclosed catheter combines the EP signal monitoring of a traditional EP diagnostic catheter, and optical energy for the ablation therapy, which is expected to provide a more efficient, accurate and reliable method of cardiac ablation than current RF techniques since it is based on real-time EP signal mapping, with precise pathological tissue localization, cardiac arrhythmia severity characterization and delivers predictable energy doses with continuous safety monitoring of the intracardiac signals.
