I have data from 12 leads of ECG. The data is from ECG signals which is taken under MRI enviorment. That means it has MHD effect, and MHD signals do have features of ICG signals . so I have plotted all the data and I am looking for B point (opning of the aortic valve, which occus in ICG signals). So the question is , normally, what is the time interval between R peak of ECG and C point (Peak point) of ICG siganls? so that i can filter out only specific leads.

Please check the attachment.

Please check the image 12Leads.png, in which the dotteted plot is reference plot of ICG, and other twelve plots are MHD plots (ECGin-ECGout), and all twelve plots are not representing the nice curve for Bpoint..

Please share your comments , if anyone working on same topic ..

Thanks and regrds..
