"This work introduces a new algorithm for the detection of P waves for this type of pathology using noninvasive electro-cardiographic surface leads. The proposed algorithm is divided into three stages. In the first stage, the R waves located by a QRS detector are used to generate the RR series and time references for the other stages of the algorithm. In the second stage, the ventricular activity (QT segment)...
