Abstract: A data processing apparatus includes circuitry configured to: receive an image of a sports player during a sports event occurring in a sports environment; determine, using the image, a pose of a foot of the sports player in a spatial model representing the sports environment; fit a shoe model to the pose of the foot of the sports player in the spatial model; determine if the shoe model in the spatial model violates a rule of the sports event indicating a region of the sports environment within which a shoe worn by the foot of the sports player can be legally positioned; and generate an output indicating if the shoe model has violated the rule.

Abstract: 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.

Abstract: An implantable medical device comprises a connector connectable to an implantable oxygen sensor configured to generate a sensor signal representative of oxygen concentration in coronary sinus blood in a subject's heart. An ischemia detector is connected to the connector and configured to detect an ischemic event in the heart if the sensor signal indicates a temporary decrease in oxygen concentration in the coronary sinus blood below a normal level followed by a temporary increase in oxygen concentration in the coronary sinus blood above the normal level.

Abstract: An implantable medical device, IMD, (100) is connectable to at least one ventricular lead (210) having a ventricular basal electrode (214) and a ventricular apical electrode (212). The IMD (100) comprises a pulse generator (120) for generating pacing pulses applied to a heart (10) through the ventricular lead (210). The operation of this pulse generator (120) is controlled by a controller (130) that is configured to control the pulse generator to first deliver a pacing pulse to the ventricular basal electrode (214) to stimulate the basal portion of the ventricle (12, 14) before a pacing pulse is delivered to the apical portion of the ventricle (12, 14) by the ventricular apical electrode (212). This pulse sequence achieves a biologically more correct cardiac stimulation and a contraction pattern that reduces the risk for valvular regurgitation.

Abstract: An implantable medical device is connected to a multipolar LV lead and an implantable sensor. The sensor signal from the sensor is used to identify a time point of mitral valve closure for a cardiac cycle when a ventricular pulse generator generates pacing pulses that are applied to the electrodes of the multipolar LV lead according to a pacing sequence. A time interval processor determines the time interval from onset of LV activation to the time point of mitral valve closure. This procedure is repeated for multiple different pacing sequences of a sequence set. The pacing sequence that resulted in shortest time interval is then selected by a selector as the currently optimal pacing sequence for the patient.

Abstract: An implantable medical device is connectable to an epicardial left ventricular lead having at least one epicardial electrode and a myocardium penetrating catheter with at least one endocardial electrode and present in a lumen of the lead. The device comprises a pulse generator controller that controls a ventricular pulse generator to generate pulses to be applied to the epicardial and endocardial electrodes. The controller uses an endocardial-to-epicardial time interval or epicardial-to-endocardial time interval to coordinate endocardial and epicardial activation of the left ventricle to thereby achieve cardiac pacing that closely mimics the natural electrical activation pattern of a healthy heart.

Abstract: In an implantable heart monitoring device and method, particularly for monitoring diastolic dysfunction, a control circuit (a) detects the heart rate, (b) derives information correlated to the stroke volume of the heart at the detected heart rate, and (c) stores the detected heart rate and the derived information correlated to the stroke volume in a memory. The control circuit automatically implements (a), (b) and (c) at a number of different occasions for a number of different, naturally varying heart rates, so that the memory contains information indicating the stroke volume as a function of the heart rate.

Abstract: An ischemia detecting system has an implantable medical device connectable to an LV cardiac catheter with sensors for generating sensor signals representative of the concentration of a constituent in coronary venous blood at different sites in the coronary venous system. The sensor signals are co-processed by the system to detect an ischemic region of the subject's heart based on a relation between the sensor signals. The detection of the particular ischemic cardiac region is possible by conducting the concentration monitoring on either sides of a branching vein in the coronary venous system and co-processing the sensor signals.

Abstract: In an implantable medical device and a method for monitoring ventricular synchronicity of a heart, impedance signals are measured that reflect septal wall movements and impedance amplitude peaks in the impedance signal are detected. A synchronicity index indicating a degree of synchronicity is determined based on detected impedance peaks, with at least two impedance peaks detected within a predetermined time window including a cardiac cycle or a part of a cardiac cycle indicating an increased dyssynchronicity in the ventricular contractions.
