    Abstract: In one example, an apparatus of a wearable cardioverter defibrillator (WCD) system comprises a support structure wearable by a patient, a plurality of electrocardiogram (ECG) electrodes to obtain an ECG signal, a processor to receive and analyze the ECG signal of the patient, wherein the processor is configured to monitor four or more channels of the ECG signal, a high voltage subsystem coupled with defibrillation electrodes configured to be coupled with patient, wherein processor is configured to cause the high voltage subsystem to apply a therapeutic shock to the patient through the defibrillation electrodes in response to a shockable event detected by the processor from the ECG signal. The processor measures a peak-to-peak amplitude of QRS complexes of the ECG signal, and detects asystole in the patient when the peak-to-peak amplitude of one or more QRS complexes is less than an asystole threshold. Other examples and related methods are disclosed herein.

    Abstract: Systems and methods are described for subject rehospitalization management. In an example, multiple physiologic signals can be obtained from a subject using multiple sensors. In response to a hospitalization event, pre-hospitalization characteristics of the multiple physiologic signals can be identified. Post-hospitalization characteristics of the multiple physiologic signals can be identified, including characteristics that differ from their corresponding pre-hospitalization characteristics. Later subsequent physiologic signals can be further monitored after the hospitalization event, such as using the same multiple sensors, and subsequent physiologic signal characteristics can be identified. In an example, a heart failure diagnostic indication can be determined using information about the pre-hospitalization characteristics, the post-hospitalization characteristics, and the subsequent characteristics. Information about relative changes in signal characteristics from multiple sensors can be used to identify particular subject physiologic signals to monitor during subsequent periods.

    Abstract: Implantable medical device for stimulating a human or animal heart. The implantable medical device performs the following steps: a) detecting, with the first detection unit, an electric signal of a heart to be stimulated, the electric signal comprising at least two consecutive amplitudes correlating with a contraction of the heart to be stimulated; b) determining i) whether a first amplitude of the two consecutive amplitudes and a second amplitude of the two consecutive amplitudes have a maximum lying within a predeterminable intensity range, and/or ii) whether a maximum of the first amplitude and a maximum of the second amplitude deviate from each other in terms of intensity by not more than 20%; and c) preventing an atrial stimulation with the first stimulation unit if at least one of conditions i) and ii) of step b), if tested, is not fulfilled, otherwise allowing an atrial stimulation with the first stimulation unit.

    Abstract: A surgical or laparoscopic method of creating and maintaining an opening in the thoracic diaphragm of a patient. The method comprising the steps of creating an incision in the thoracic diaphragm and thereby creating an opening in the thoracic diaphragm, placing a diaphragm passing part in said opening created in the thoracic diaphragm, passing from the abdomen through the thoracic diaphragm and into the thorax; wherein the step of placing said diaphragm passing part comprises placing a force transferring part of the diaphragm passing part in contact with the thoracic diaphragm, the force transferring part being adapted to transfer force between the abdominal side of the thoracic diaphragm and the thoracic side of the thoracic diaphragm while sliding against the thoracic diaphragm.
