Abstract: Long-term electrocardiographic and physiological monitoring over a period lasting up to several years in duration can be provided through a continuously-recording subcutaneous insertable cardiac monitor (ICM). The sensing circuitry and the physical layout of the electrodes are specifically optimized to capture electrical signals from the propagation of low amplitude, relatively low frequency content cardiac action potentials, particularly the P-waves that are generated during atrial activation. In general, the ICM is intended to be implanted centrally and positioned axially and slightly to either the left or right of the sternal midline in the parasternal region of the chest. Additionally, the ICM includes an ECG sensing circuit that measures raw cutaneous electrical signals and performs signal processing prior to outputting the processed signals for sampling and storage.

Abstract: A self-authenticating electrocardiography and physiological sensor monitor is provided. A strip includes two rounded ends with a mid-section between the rounded ends. An electrocardiographic electrode is provided on each of the rounded ends. A flexible circuit is mounted to a surface of the strip and includes a circuit trace electrically coupled to each of the electrocardiographic electrodes. A flash memory is positioned on one of the rounded ends to store ECG data collected via the electrocardiographic electrodes and a battery is positioned on one of the rounded ends. A processor is positioned on one of the rounded ends and configured to execute an authentication protocol that checks voltage of the battery and a state of the flash memory, and determines an expiration of the strip.

Abstract: Circuitless heart cycle determination includes capturing a video clip of one or more image frames of a target heart muscle through an ultrasound imaging device and submitting the frames to a classifier that has been trained with an annotated set of images, each of a corresponding heart muscle captured at a specified phase of a heart cycle with a ground truth indication of the specified phase of the heart cycle drawn from a separately recorded cycle graph of an electrical signal measured over time for the corresponding heart muscle. In response to the submission, a classification is received of different portions of the submitted frames according to corresponding phases of the heart cycle. Finally, a contemporaneous phase of the heart cycle is determined in the device for the target heart muscle without sensing electrical signals by way of a closed-loop sensor circuit affixed proximately to the target heart muscle.

Abstract: A self-authenticating electrocardiography and physiological sensor monitor is provided. An electrode patch includes an elongated strip and electrodes exposed on each end. A receptacle is adhered to the elongated strip and includes electrical pads. Circuit traces are electrically coupled to the electrocardiographic electrodes and the electrical pads. A monitor recorder having a sealed housing is adapted to be secured into the receptacle. Circuitry within the housing includes a microcontroller with a private key. A copy of the private key is stored on the patch. Self-authentication is performed each time the monitor recorder is inserted into a new patch by challenging the patch using a code hashed with the private key and by receiving a response from the patch in reply to the challenge. A front end circuit senses electrocardiographic signals via electrodes on the patch when the response received by the microcontroller is positive, until the electrode patch expires.

Abstract: A noise-separating cardiac monitor is provided. An implantable housing includes an external surface. A wireless antenna is shaped to wrap around an interior periphery of the implantable housing. Electrodes are provided on a ventral surface of the implantable housing to capture P-wave signals and R-wave signals. Electronic circuitry is provided within the wearable housing and includes a low power microcontroller. A front end circuit includes a signal lead operable to sense cardiac electrical potentials through one of the electrodes, a reference lead operable to sense the cardiac electrical potentials through another electrode, and a reference generator configured to inject a driven reference to the reference lead. The signal lead includes a coupling capacitor and a protection resistor associated with thermal noise. The thermal noise is not contained in the driven reference and not introduced to the reference lead. A non-volatile memory is electrically interfaced with the microcontroller.
