description The invention discloses an atrial septal defect detection method based on a second heart sound splitting coefficient. The method comprises the following steps: S2, automatically segmenting and extracting a second heart sound; defining a second heart sound splitting coefficient # imgabs0 # and calculating a second heart sound splitting time interval # imgabs1 #; the invention discloses an atrial septal defect detection method and evaluation indexes. According to the atrial septal defect detection method based on the second heart sound splitting coefficient, performance evaluation and verification are carried out on a standard database and clinical data, and high-precision (gt; 95%) can be automatically detected. 本发明公开了一种基于第二心音分裂系数的房间隔缺损检测方法,包括第二心音S2自动分割提取;第二心音分裂系数#imgabs0#定义及第二心音分裂时间隔#imgabs1#计算;房间隔缺损检测方法及评价指标。本发明采用上述一种基于第二心音分裂系数的房间隔缺损检测方法,通过对标准数据库与临床数据进行性能评估及验证,可实现房间隔缺损型心音高精度(>95%)自动检测。
