Hello Viewers, in this video, a scheme is presented to detect QRS complex (R-Peaks) of an ECG signal using undecimated Discrete Wavelet Transform (DWT). It is shown that how band pass filtering of ECG signal is achieved to preserve R-peaks using DWT which is superior than frequency selective BPF. Also by counting total number of R-peaks are counted Heart Rate (in beats per minute) is also calculated. Also robustness of the proposed scheme is shown on different types of ECG signals taken from MIT-BIH arrhythmias and ECG-ID databases from PhysioNet.

Thank You Sir

[@jarjarwong7554]

How can i load my own ECG data into it?

[@nganhalamnguyen]

Thank you for your video. I find it very interesting. I am curious in case I want to find T-peak, what should I do? And I haven't been clear about the bandpass filter you mentioned but I don't see it in the code.

[@exploringtechnologies9]

Removing low frequency coeffs. and high freq. coeffs. at certain levels create bandpass effect. For T-peaks, we have to find another approach.

Fantastic video! Great efforts Dr AK 🎉.
Does Sym4 work with most arrhythmias?

[@exploringtechnologies9]

I think yes

[@bhargavmistry1274]

​@exploringtechnologies8626 great! Would that be any delay between Leading edge/peak of R wave of original signal and the detected one highlighted with red circle? If yes how to rectify it, plz?

[@user-ox3jd6hx7f]

Respected sir, I have copied and run your codes but I'm facing an issue that is "Error using modwt (line 138)
Invalid transform level." I didn't get the result. What should I do?

[@exploringtechnologies9]

Check matlab version. I have used 2018a

[@EEk--HammadAhmed]

What are other parameters that we can compute for ecg signal analysis. My fyp is related to ecg signal parameters computing and its analysis. Will you guide me further in this regard. Thanks

[@exploringtechnologies9]

Study more research papers in this area.

sir
how to get qrs interval using the same code

[@exploringtechnologies9]

QRS interval is just gap between two R peaks. Find it by simply difference.

[@dhimanbiswas4643]

@@exploringtechnologies9 SIR THE GAP BETWEEN TWO R PEAKS IS CALLED RR INTERVAL. I AM ASKING ABOUT THE FINDING OF QRS COMPLEX INTERVAL USING THE SAME MATLAB CODE.
