Analysis of phonocardiogram and electrocardiogram data from portable sensor devices

摘要

It is presented a method for analysing heart data of a user. The method comprises the steps of: receiving phonocardiogram data from a portable sensor device; receiving electrocardiogram data from the portable sensor device, wherein the electrocardiogram data corresponds to the phonocardiogram data in time; dividing the phonocardiogram data in time segments based on cardiac cycles identified using at least one of the phonocardiogram data and the electrocardiogram data; dividing the electrocardiogram data in time segments corresponding to the time segments of the phonocardiogram data; and determining whether the heart is considered to need further examination or not based on only time segments of the phonocardiogram data and the electrocardiogram data where the quality of the phonocardiogram data is greater than a threshold level and the quality of the electrocardiogram data is greater than a threshold level.
