摘要： An implantable cardiac stimulation device has an atrial detector that detects atrial events of a patient's heart, and a memory in which sequences of IEGM signals are stored, having a predetermined length, and an analyzing unit that analyzes the sequences to determine if the stored sequences contain atrial events having a lower amplitude than the current sensitivity setting of the atrial detector. A control unit is connected to the atrial detector to adjust the sensitivity setting thereof to a threshold that is determined based on the aforementioned analysis of the IEGM signals.

摘要： An implantable bi-ventricular heart stimulating device (10) has a control circuit with first and second sensing circuits for respectively sensing in the two ventricles and first and second stimulation circuits for respectively stimulating the two ventricles. The control circuit determines whether a signal, sensed by said second sensing circuit, occurs essentially simultaneously with a signal sensed by the first sensing circuit. Furthermore, the control circuit determines whether a further signal is sensed by said second sensing circuit within a predetermined time interval which follows after the signal sensed by the second sensing circuit but within the same time cycle as that signal. If this occurs, the control circuit determines whether the sensed signals represent actual cardiac events, or are likely the result of far field detection.

摘要： In a method and an implantable medical device for assessing a degree of pulmonary edema of a patient, at least two specific body patients of the patent are detected and at least one impedance sensing session is initiated to sense trans-thoracic impedance signals from the patient when the patient is in one of the at least two specific positions. Impedance values are obtained from the impedance signals, and a relation between respective impedance values at the at least two positions is determined. This relation is then used as a metric of pulmonary edema to assess the degree of pulmonary edema, and is provided as an output.

摘要： In a biventricular heart stimulator and a method for controlling such a biventricular heart stimulator, successive stimulation pulses are delivered to the ventricles of a heart such that stimulation pulses in a single heartbeat cycle are respectively first delivered to the first ventricle and then to the second ventricle. Capture or loss of capture in response to stimulation pulses delivered to one ventricle is detected. As a result of a detected loss of capture, preventative measures are taken for preventing loss of capture in the other ventricle.

摘要： In a device and method in a dual chamber pacing system operating in an atrial synchronized mode, the cardiac stimulator is connectable to a lead arrangement arranged for sensing atrial electrical and mechanical activity. Upon detection of an atrial arrhythmia based on either of sensed atrial mechanical activity, atrial electrical activity, or a combination thereof, a mode switch from an atrial synchronized ventricle stimulating mode to a non-atrial synchronized mode is triggered.

摘要： An implantable heart stimulating device for indicating congestive heart failure (CHF) has a processor, an activity sensor that generates an activity signal indicative of a patient's activity, and a blood temperature sensor that measures blood temperature inside the heart of the patient and generates a temperature signal indicative of the measured temperature. From the activity signal and the temperature signal, the processor identifies a characteristic dip in the temperature signal related to a predetermined increase in the activity signal. The processor determines a CHF indicator value indicating the degree of CHF based on the magnitude of the temperature sensor dip for at least two increased activity levels.

摘要： In an implantable heart stimulating device, system and method, electrical stimulation pulses are delivered to first and second ventricles of a heart with a variable time interval therebetween, and signals are sensed at two different positions in the heart, from which an impedance value is derived. A minimum value and a maximum value of the impedance value are determined during a heart cycle, and a relationship between the minimum and maximum values also is determined. The time interval is varied and the relationship is monitored over a number of heart cycles. The time interval is set so that the relationship satisfies a predetermined requirement.

摘要： In an implantable medical device, such as a pacemaker or a cardioverter/defibrillator, and a method for operating such an implantable medical device, heart conditions, such as heart failure, are detected and predicted at an early stage within a patient in whom the medical device is implanted, by monitoring a patient status, for example, HF status, and predicting a worsening of the HF status of the patient and determining a patient status index, wherein a first average and a second average is compared at predetermined sample points of time. A patient status is determined based on this patient status index, wherein a patient status index that has increased substantially monotonously during a first monitoring period is determined to be an indication of an exacerbation of patient status, and in particular, a worsening of heart failure.
