Abstract[English]
The present application relates to the technical field of medical signal processing. Disclosed are a heart-sound segmentation method and apparatus, and an electronic device and a readable storage medium. The heart-sound segmentation method comprises: synchronously collecting physiological signals, wherein the physiological signals comprise a heart sound signal; acquiring a segmentation threshold value corresponding to the heart sound signal, and segmenting the heart sound signal on the basis of the segmentation threshold value, so as to obtain a first heart sound and a second heart sound; and on the basis of the first heart sound and the second heart sound, determining the systole duration of the heart sound signal and the diastole duration of the heart sound signal. The present application reduces the consumption of resources for heart sound segmentation of heart sound signals.[French]
La présente demande se rapporte au domaine technique du traitement de signal médical. Sont divulgués un procédé et un appareil de segmentation de son cardiaque, un dispositif électronique et un support de stockage lisible. Le procédé de segmentation de son cardiaque consiste en : la collecte synchrone de signaux physiologiques, les signaux physiologiques comprenant un signal sonore cardiaque ; l'acquisition d'une valeur seuil de segmentation correspondant au signal sonore cardiaque, et la segmentation du signal sonore cardiaque sur la base de la valeur seuil de segmentation, de façon à obtenir un premier son cardiaque et un second son cardiaque ; et sur la base du premier son cardiaque et du second son cardiaque, la détermination de la durée de systole du signal sonore cardiaque et de la durée de diastole du signal sonore cardiaque. La présente demande réduit la consommation de ressources pour la segmentation de son cardiaque de signaux sonores cardiaques.[Chinese]
本申请公开了一种心音分割方法、装置、电子设备及可读存储介质，本申请涉及医学信号处理技术领域，所述心音分割方法包括：同步采集生理信号，其中，所述生理信号包括心音信号；获取所述心音信号对应的分割阈值，基于所述分割阈值分割所述心音信号，得到第一心音与第二心音；根据所述第一心音、第二心音确定心音信号的收缩期持续时长与心音信号的舒张期持续时长。本申请降低了心音信号的心音分割资源耗费。
