Abstract: A method includes retrieving a plurality of indications of cardiac events in a patient, heart rates of the patient during the cardiac events, and durations of the cardiac events. The method also includes selecting a subset of indications from the plurality of indications based on the heart rates of the patient during the cardiac events and the durations of the cardiac events and sorting the subset of indications based on heart rates of the patient during the cardiac event indicated by the subset of indications and based on durations of the cardiac events indicated by the subset of indications to produce a sorted list of indications. The method further includes communicating, from the sorted list, an indication that is first in the sorted list for clinical review.

Abstract: 本申请涉及信息技术处理领域，公开了一种早搏检测方法及其电子设备和介质。本申请的早搏检测方法包括：采用早搏检测功能对用户进行早搏检测，在采用早搏检测功能检测出用户出现早搏的情况下，采用早搏类型判断功能判断用户出现的早搏类型，并基于早搏检测功能得到的检测数据计算用户的早搏负荷，在计算出的早搏负荷大于早搏类型判断功能判断出的早搏类型所对应的早搏负荷阈值的情况下，对用户进行早搏风险提醒。本申请的早搏检测技术避免了电子设备的单一检测功能能够持续进行早搏检测但无法识别早搏类型的缺点，综合利用两个检测功能实现早搏的持续检测和早搏类型的判定，进而实现两种不同类型早搏的差异化风险提醒，避免大量错误提醒或对风险认识不足。

Abstract: A method for detecting an ectopic signal in an electrocardiogram is disclosed. This method comprises the following steps: detecting consecutive R-R intervals in an electrocardiogram; calculating an average R-R interval for a determinable number of latest R-R intervals; recognizing a signal as ectopic signal if the signal belongs to at least one of two consecutive R-R intervals, wherein i) a first of the two consecutive R-R intervals is significantly shorter than the average R-R interval; and ii) a second of the two consecutive R-R intervals is significantly longer than the average R-R interval, wherein the second R-R interval occurs later than the first R-R interval; wherein the first and the second of the two consecutive R-R intervals are discarded from calculating the average R-R interval, if the signal is recognized as ectopic signal.

Abstract: The invention relates to an implantable medical device, comprising a processor, a memory unit, a first detection unit configured to detect an atrial electric signal of a human or animal heart, and a second detection unit configured to detect a ventricular electric signal of the same heart. During operation of the device, atrial events are evaluated in the atrial electric signal detected by the first detection unit and/or ventricular events are evaluated in the ventricular electric signal detected by the second detection unit for recognizing a condition of the implantable medical device in which atrial electric signals are detected only insufficiently. This evaluation is done by applying at least one of the following criteria: - morphology of the detected atrial electric signals; - lacking stability of atrial events; - absence of atrial events over a first period of time; - detection of an amplitude of the detected atrial electric signal being lower than a predefined threshold value; - absence of atrial events during detection of ventricular electric signals at the same time; comparison of atrial events sensed with a first sensing profile of the first detection unit and atrial events sensed with a second sensing profile of the first detection unit, the second sensing profile being more sensitive than the first sensing profile.

Abstract: A method for health monitoring is provided including at least one non-invasive wearable device capable of collecting and storing data, and external monitoring devices that displays and analyses the data for accurate monitoring and anomaly detection. The wearable devices are configured to collect low-latency PPG-derived bio signals and can utilize multiple devices for accuracy and continuity. The system may further include a dashboard that analyzes the information as well as displaying basic information such as number of beds (in-use, available), staff-to-patient ratio, etc. The data can be collected and accessed remotely and may be utilized before, during, and/or after a patient is dispatched from a clinical setting.

Abstract: Methods, apparatus and systems for robust and accurate detection of anomalies in medical images and electrocardiograms are disclosed. One example system for training a neural network engine includes a processor that is configured to receive a set of training electrocardiogram signals. At least one electrocardiogram signal in the set of training electrocardiogram signals is associated with metadata identifying a region of interest that includes a heart anomaly. The processor is configured to input the set of training electrocardiogram signals into the neural network engine. The neural network engine is trained using an objective function having a first regularization parameter and a second regularization parameter. The processor is also configured to operate the neural network engine to identify the heart anomaly by classifying the set of training electrocardiogram signals and adjust the neural network engine based on the identified heart anomaly and the metadata.

Abstract: A method for automatically and independently associating a cardiovascular disease with an electrocardiogram, ECG, signal includes receiving (1800) the ECG signal; denoising (1802) the ECG signal using a wavelet transform; determining (1804) peaks of the denoised ECG signal by applying a combination of (1) two event-related moving averages and (2) fractional-Fourier-transform (FrFT) to the denoised ECG signal; and passing (1806) the peaks through a classifier for identifying the cardiovascular disease that corresponds to the ECG signal.

Abstract: The present disclosure relates to a method for monitoring an implantable device (200, 500, 601, 602). The method comprises: receiving at least one cardiac vector signal (230-1, 230-2), wherein the at least one cardiac vector signal is acquired by the implantable device between at least one pair of electrodes (213, 212); extracting two or more separate features (A, B, C, J) from the at least one cardiac vector signal by signal processing; deriving a hardware status (pnoise) of the implantable device based at least in part on a classification of the extracted two or more separate features.
