WebMay 11, 2024 · There is obvious 60 Hz line noise. Use a bandstop filter with a very narrow stopband to eliminate it. Beyond that, it appears to represent normal sinus rhythm with left ventricular hypertophy with non-specific ST-T changes and one notable PVC. If this is a Lead II EKG, the origin of the PVC appears to be near the apex. WebMay 10, 2024 · May 10, 2024 at 13:55 The most simple way is to make the filter by constructing an array which is full of zeros and only contains 1s for the frequencies we want to keep. Pre-defined functions like fir2 are beyond the scope of my DSP course, so I am trying to do it using this simple approach. – Merin May 10, 2024 at 14:27 grandmothers against poverty and aids
