通常情况下只能听到第一心音(first heart sound,S1)、第二心音(second heart sound,S2)。第三心音(third heart sound,S3)可在部分青少年中闻及。第四心音(fourth heart sound,S4)属于病理性心音。 图1 第一心音和第二心音 图2 第一心音和第二心音 第一心音的产生机制...
S1 and S2 recognitionRecently, we have proposed a deep learning based heart sound recognition framework, which can provide high recognition performance under clean testing conditions. However, the recognition performance can notably degrade when noise is present in the recording environments. This study ...
Most work done in Heart Sound Segmentation approaches use a threshold-based approach to correctly identify S1 and S2 segments in a given signal. We propose... N Marques,R Almeida,AP Rocha,... - IEEE 被引量: 4发表: 2013年 Automatic Segmentation of Heart Sounds (S1 & S2) Using Wavelet ...
S1 and S2 heart signals, which are also called the cycle of “lub dub” are two major sounds of a normal heart sound. S1 is composed of components M1 (mitral) and T1 (tricuspid) which are valvular sounds, whereas S2 is composed of components A2 (aortic) and P2 (pulmonic) valve ...
