摘要： A patient-specific hemodyanmic status model is determined from impedance data collected during periods of normal and abnormal hemodynamic status by deriving parameter values of a set of multiple impedance-derivable parameters from impedance signals collected during periods of normal hemodynamic status and in connection with periods of abnormal hemodynamic status. The parameter values are employed to estimate coefficients of a linear parametric status model. These coefficients can then be used together with parameter values determined from impedance signals determined during status assessment periods in order to determine a current hemdoynamic status of the patient.

摘要： An implantable medical device, is designed to collect a signal representative of the electric activity of the heart and determine a cardiogenic impedance signal for at least a portion of the heart. An R-wave detector of the IMD detects the timing of an R-wave during a cardiac cycle based on the signal representative of the electric activity. A minimum detector detects the timing of a cardiogenic impedance minimum in the cardiogenic impedance signal and within a systolic time window of the cardiac cycle.

摘要： An implantable medical device (100) is configured for generating a cardiogenic impedance signal representative of the cardiogenic impedance of at least a portion of a heart (10) of a subject (20) during multiple cardiac cycles. A transform processor (132) generates a spectrum signal by applying a time-to-frequency transform to the cardiogenic impedance signal. The spectrum signal is processed by a distribution processor (133) configured to calculate a distribution parameter indicative of a distribution in at least a portion of the spectrum signal. The calculated distribution parameter is of high diagnostic value and is employed by an arrhythmia classifier (134) in order to classify a detected arrhythmia of the heart (10), such as discriminate between hemodynamically stable or unstable arrhythmias and/or supraventricular or ventricular tachycardia.

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.

摘要： A pacemaker has control circuits contained in an enclosure and a lead containing an electrical conductor connected to an electrode for delivering electrical stimulation pulses to a heart. The stretching of a wall in the ventricle, corresponding to adequate filling of the ventricle in the heart, is determined in order to identify a time of emitting the stimulation pulses. This stretching is measured indirectly by measurement of pressure in the ventricle using a pressure sensor disposed near the lead in the ventricle. The signal from the sensor is supplied via the lead to circuitry in the enclosure, wherein the signal is amplified and is supplied to an edge detector, which detects an increasing or positive edge of the signal. The edge detector compares the incoming signal with a threshold value, and when the pressure indicated by the signal increases so as to exceed the threshold value, the edge detector supplies a signal to the control circuit which, in turn, triggers the emission of a stimulation pulse from a pulse generator, with or without a delay. The aforementioned stretching can also be measured using a strain gauge or a distance sensor attached to the ventricle wall.

摘要： A device for identifying abnormal conditions in a heart retrograde conduction and tachyarrhythmias in particular, includes a differentiating circuit electrically connected to a heart to be monitored in order to differentiate ECG signals from the heart. The differentiated signal is plotted against the ECG signal. The radius (distance from a point on the resulting curve from the origin of the plot axes) in the resulting curve is calculated in a calculator unit. The radius obtained is then compared with a threshold value in a comparator and a sequence for the progression of the radius in relation to the threshold value is obtained and compared with previously obtained sequences stored in a sequence analyzer.
