Im student Electronics, so im sorry if i have some lack in biosignal analysis thats why i ask you guys this:
I've created my own ECG monitor with instrumentation amplifier, high pass filter(0.1Hz) and low pass filter(40Hz). The added picture shows my captured data with method: Einthovens Lead 1(measurement is from real person at chest), can someone explain me why the signal goes upwards / downwards after T wave? I've already aplied highpass(for removing drift) and lowpassfilter(for removing noise) in matlab program.
I would like to calculate the QRS time, but its not possible in this way as Q is not my minimum value.
