Abstract: The present application relates to a field of image processing and discloses an ECG image processing method, device, medium, and an electrocardiograph. The ECG image processing method of the present application includes: receiving the ECG image; extracting a feature map of the ECG image, and reducing the feature map to obtain an attention map; extracting a feature matrix from the feature map and the attention map using a bilinear attention pooling; obtaining an expression matrix using an adaptive weight learning and a weighted fusion of the feature matrix by a multi-headed self-attention processing; and classifying the ECG image with a plurality of labels. This application allows direct interpretation of ECG images without limiting to a use of conventional digital signals, while capturing subtle discrepancies in the ECG image for classifying ECG abnormalities with high noise immunity.

Abstract: A method for determining cardiology disease risk from electrocardiogram trace data and clinical data includes receiving electrocardiogram trace data associated with a patient, receiving the patient's clinical data, providing both sets of data to a trained machine learning composite model that is trained to evaluate the data with respect to each disease of a set of cardiology diseases including three or more of cardiac amyloidosis, aortic stenosis, aortic regurgitation, mitral stenosis, mitral regurgitation, tricuspid regurgitation, abnormal reduced ejection fraction, or abnormal interventricular septal thickness, generating, by the model and based on the evaluation, a composite risk score reflecting a likelihood of the patient being diagnosed with one or more of the cardiology diseases within a predetermined period of time from when the electrocardiogram trace data was generated, and outputting the composite risk score to at least one of a memory or a display.

Abstract: A non-invasive and convenient method and apparatus for approximation of left ventricular end diastolic pressure (LVEDP) can be used in both hospital/clinic environments and nursing home or home environments. The method and apparatus use non-invasive sensors and a new “cardiac triangle” computational method to obtain an approximation of LVEDP. The computational method uses hemodynamic and electrocardiogram (ECG) waveforms as input, which can be collected by a portable device or devices.

Abstract: An ultrasonic wave diagnostic apparatus according to an embodiment includes processing circuitry. The processing circuitry acquires a plurality of pieces of volume data obtained through image capturing of a region including the cardiac ventricle of a subject for a predetermined duration. The processing circuitry estimates motion of tissue of the cardiac ventricle by using the pieces of volume data. The processing circuitry calculates, based on a result of the estimation, cardiac ventricle information indicating at least one of wall motion information and volume information related to the cardiac ventricle. The processing circuitry calculates, based on a result of the estimation, annulus information related to the size or shape of an annulus position of a valve related to inflow or outflow of blood current at the cardiac ventricle. The processing circuitry outputs the cardiac ventricle information and the annulus information.

Abstract: Devices and methods for monitoring physiologic parameters are described where an airway device, in one embodiment, may comprise a mouthpiece section and an opening section defining one or more airway lumens therethrough with a first sensor in fluid communication with the one or more airway lumens and a second sensor positioned upon a hand-piece for contact against a portion of the user. The first sensor may be configured to detect an airway pressure when a user inhales or exhales through the one or more airway lumens, and the second sensor may be configured to detect a physiological signal from the user. Additionally, a controller may be in communication with the first and second sensors where the controller is programmed to correlate pressure oscillations in the airway pressure with heartbeats.
