Abstract
For the cardiovascular desease early diagnosis by the remote monitoring systems the fonokardiosyhnal (as periodically correlated random process) simultaneously registered with electrocardiosignal usage is proposed. An registered signal preproccesing procedure, groundet in this article, is carried out by the following algorithm: detrending procedure (the constant component of the signal (trend) reducing), smoothing (high noise suppression with minimal spectrum distortion and P-peacs offset locations), the P-peacs repeating intervals determination.
