Kindly check the vi with these recorded signals wheather the vi is working properly, these are the recorded signals from my DAQ device.

I looked at your files and I do not see much in the way of ECG. The signals are dominated by what I will assume to be a respiration signal. The ECG is there, but of such small amplitude that your filtering cannot be selective enough to separate it from the respiration signal.
If this is the best signal for ECG that you can acquire, then you will have to figure out a new approach.

thanks you for your reply, ya this is the best signal I could get from Daq acqusition, in fact I have sent you only the better ones, so what method can I use with such a signal, as I am dealing with these signals only and the other conventional ECG I sent before was just used to compare both the ECG's.
ya your right here respiration signals are overlapping with ECG, so is there any way to deal in such a situation.

I have a try of you signal of "R10-R10_closed cover_Bhavin1_1.lvm". ECG signal is very weak. However, choosing a suitable filter will help improve the SNR. Then using peak detection technique to find the heartbeats.
During the peak detection ,the threshold should be adaptive as the ECG signals are so weak and changing. Here I only set to a fixed threshold 0.02. For adaptive threshold in ECG QRS detection, you could refer to the paper (although it is very old )
