  • Publication number: 20230372702
    Abstract: In embodiments, a wearable cardiac defibrillation (WCD) system includes one or more flexible ECG electrodes. The WCD system may have a support structure that is dimensioned to be worn so as to press the electrodes towards the body of the patient. The electrodes may be made from appropriate material so as to flex in order to match a contour of the body of the patient. An advantage over the prior art is that the flexible electrode may make better electrical contact with the patient's skin, and therefore provide a better ECG signal for the WCD system to perform its diagnosis.

  • Patent number: 11278730
    Abstract: In embodiments, a wearable cardioverter defibrillator (WCD) system includes a support structure configured to be worn by an ambulatory patient, an energy storage module configured to store an electrical charge, at least one defibrillation electrode held on the patient while the patient is wearing the support structure, and sensors. The sensors may include a rotational measurement module, a magnetic field sensing module, a pulse detector and an ambient air pressure sensor. The sensors may gather multiple data about the patient, which can be used for better understanding of the patient's activities and ultimately a better-informed defibrillation decision.

  • Patent number: 11000692
    Abstract: Embodiments are directed to wearable cardioverter defibrillator (WCD) systems that include patient parameter electrodes, such as ECG electrodes, that are at least substantially electrically isolated from other circuits of the WCD system. In embodiments, the WCD system includes a power source, an energy storage module, and a processor each connected to a first circuit ground. A patient parameter sense port, such as an ECG port, is coupled to the patient. A measurement circuit may render a physiological input from the sensed patient parameter received at the patient parameter sense port, and the measurement circuit includes an isolating circuit that electrically isolates the patient parameter sense port from the first circuit ground. The sensing of physiological inputs of the patient can be improved, resulting in fewer erroneous readings and false alarms.
