Cardiac-acoustic-map

The sampling rate of the data is 10 kHz. data_original.txt is the original data of the multichannle heart sound signals. data_preprossed.txt is the preprocessed data of the multichannle heart sound signals. The 73th channel is the ECG.And the 1-72th channels are the heart sound signal The cardiac acoustic map was drawn based on the data_preprossed.txt. HS_S1.avi is the cardiac acoustic map of S1 from 0.204s to 0.322s of the preprocessed data. HS_S2.avi is the cardiac acoustic map of S2 from 0.469s to 0.536s of the preprocessed data. The background_image is the hunman skeleton image, which is the background of the cardiac acoustic map. The sensor_coor is coordinates of the sensors in the background_image, which first column is the number of the sensor, the second column is the row coordinate of the sensor, and the third column is the column coordinate of the sensor. The image of the number of the sensors shows the sensors arrangement.
