Buy This Project Hello friends, I hope you are doing great. Today, I am going to share an expert level project which is ECG Averaging in MATLAB. If you are new to ECG then you should have a look at Introduction to ECG. I have already shared ECG Simulation using MATLAB in which we have seen how to simulate an ECG signal and then diagnose heart disease. We have also extracted ECG features in that project. So, if you guys haven't read that tutorial then I would suggest you to not read this one. First read ECG Simulation using MATLAB and then you should read this tutorial. Today's project is quite an extension of our previous project ECG Simulation using MATLAB. Our team has designed this project after quite a lot of effort that's why its not free to use but you can easily buy it from our shop using PayPal, by clicking the above button. In today's tutorial, we are gonna have a look at How to do ECG Averaging in MATLAB. ECG Signals normally have a lot of noise in them that's why its quite necessary sometimes to average the ECG signal so that we get better results. That's where ECG averaging is required. So, lets get started with ECG Averaging in MATLAB.

ECG Averaging in MATLAB

Let me first explain in detail why we need to average an ECG signal and how we are gonna do that.
Check ECG signal shown in below figure:

In the above ECG signal, we can see there's a lot of noise in ECG waveform, which may affect our results so there's a need to apply some filters to smoothen out the ECG waveform.
Another way of removing noise is ECG averaging.

In ECG averaging technique, we cut signle ECG signal and then we extract all of our peaks.
Finally we add them up and create an average waveform.
I have shown this whole procedure in below figure:

In the above figure, you pretty much got the idea behind this project.
Now here's its MATLAB GUI, shown in below figure:

It has two Containers at top and a full length Graph at the bottom.
Now, when you Click the Button the it will ask for the ECG data file, as shown in below figure.
Currently this project has eight data files with it and I have tested all of them and they are working quite fine.
I have downloaded all the data files from Phsio Bank website. You can read its more details in ECG Simulation using MATLAB.
Now when you will upload the files then it will take all the peaks and then will add them up one by one and will give you final output in the right container.
The whole procedure for data1 is shown in below figure:

I hope now you got the complete idea of its working but still if you have any questions then you can ask in comments and I will help you out.
Here's the final look of this project:

I have also created this video in which I have explained it in more detail and shown how it works.
So, if you wanna buy this Project then I would suggest you to must watch this video before so that you got the complete idea of what you are buying.
Here's the video for ECG Averaging in MATLAB:

So, that's all for today. I hope you have enjoyed today's tutorial. Will see you guys in next tutorial. Till then take care and have fun !!! :)
