Most of the energy of the QRS complex lies between 3 Hz
and 40 Hz [25]. The 3-dB frequencies of the Fourier Transform
of the wavelets indicate that most of the energy of the QRS
complex lies between scales of 23 and 24, with the largest at 24.
The energy decreases if the scale is larger then 24. The energy
of motion artifacts and baseline wander (i.e., noise) increases
for scales greater then 25. Therefore, we choose to use
characteristic scales of 21 to 24 for the wavelet.
The detection of the QRS complex is based on modulus
maxima of the Wavelet Transform. This is because modulus
maxima and zero crossings of the Wavelet Transform
correspond to the sharp edges in the signal. The QRS complex
produces two modulus maxima with opposite signs, with a zero
crossing between them shown in Fig. 7. Therefore, detection
rules (thresholds) are applied to the Wavelet Transform of the
ECG signal. The Q and S point occurs about the R Peak with in
0.1second. The left point denoted the Q point and the right
one denotes the S point. Calculating the distance from zero
point or close to zero of left side of R Peak within the threshold
limit denotes Q point. Similarly the right side denotes the S
point.
