ECG delineation state machine. State Machine flow chart for online ECG delineation. The zero-corssing n _Z with the largest modulus-maxima pair amplitude A _MMp (n _Z ) is detected within ΔW_QRS (250 ms) at scale 2². Detail coefficients d^k _n at scales 2² and 2³ are parsed for the verification of QRS candidates according to the QRS-detection decision rule. After QRS-complex detection, the delineation process delineates in the order: the QRS-complex, the P wave, and the T wave.
