Abstract :
A new QRS detection algorithm using resonance theory is presented. After showing that the gradient of amplitude of ECG is proportional to frequency, we proposed an index function P which uses it as input. When it is equivalent to the value of the QRS characteristic frequency, the index function P returns to the very low value. Setting the detection threshold, we can finally detect QRS complexes. The new algorithm showed comparable or higher performance than other algorithms
