Abstract
A technology for determining an indication of heart failure of a subject (18) is proposed. It comprises: obtaining (100a) a first signal interval (36) from a source signal recorded with an accelerometer (14) placed on the chest of a subject (18), wherein the first signal interval (36) corresponds to a first subinterval of a heart cycle; inputting (200a) the first signal interval (36) into a first autoencoder, wherein the first autoencoder is trained on the corresponding first signal intervals obtained from healthy subjects and outputs a reconstructed first signal interval (44), determining (300a) a first correlation between the first signal interval (36) and the reconstructed first signal interval (44), and determining (400) the indication of heart failure based on the first correlation.
