摘要： A leadless pacemaker device (1) configured to provide for an intra-cardiac pacing comprises a processing circuitry (15) configured to generate ventricular pacing signals for stimulating ventricular activity at a ventricular pacing rate, a first sensor arrangement configured to receive a first sense signal, and a second sensor arrangement configured to receive a second sense signal. The processing circuitry (15) is configured to derive, in a first sensing state, atrial events (As) from the first sense signal for controlling the ventricular pacing rate based on said atrial events (As). The processing circuitry (15) is further configured to switch, based on at least one switching criterion, from the first sensing state to a second sensing state in which the processing circuitry (15) is configured to derive atrial events (As) from the second sense signal.

摘要： In general all embodiments relate to implantable medical devices 16 including at least one injectable device and at least one anchor 12 for fixation of the injectable device to body tissue. The anchor 12 of the implantable medical device 16 fulfills the requirement for secure anchoring of the injectable device to body tissue. The medical device includes at least one contrast agent reservoir 20 with an outlet 36, wherein the reservoir 20 is filled with a contrast agent 14, which may be released through the outlet 36 into body tissue or cavities. The contrast agent 14 is able to be visible with known imaging methods comprising X-ray or MRI imaging or other well-known techniques to determine if a secure anchoring of the medical device 16 has been achieved.

摘要： A leadless pacemaker device (1) configured to provide for an intra-cardiac pacing comprises a processing circuitry (15) configured to generate ventricular pacing signals for stimulating ventricular activity at a ventricular pacing rates and a sensor arrangement configured to receive a sense signal over a multiplicity of heart cycles. The processing circuitry (15) is configured to derive, from signal portions (S) of the sense signal relating to the multiplicity of heart cycles, a combined signal portion ( S comb ) and to analyze said combined signal portion ( S comb ) for obtaining information relating to an atrial event (As). In this way a leadless pacemaker device is provided allowing, in particular, for a reliable detection of signals relating to an atrial activity and to use such signals for controlling a ventricular pacing rate for a ventricular pacing.
