WebFeb 4, 2024 · QRS Width. Normal QRS width is 70-100 ms (a duration of 110 ms is sometimes observed in healthy subjects). The QRS width is useful in determining the origin of each QRS complex (e.g. sinus, atrial, junctional or ventricular). Narrow complexes (QRS < 100 ms) are supraventricular in origin. Broad complexes (QRS > 100 ms) may be … WebDec 7, 2024 · The right and left atria or upper chambers make the first wave called a “P wave" — following a flat line when the electrical impulse goes to the bottom chambers or ventricles. The right and left bottom chambers make the next wave called a “QRS complex."

I would suggest a 0.20 Hz low-frequency passband limit but your sampling frequency will only allow you at most 250 Hz at the high end. You need to do FFTs of at least Lead II of each EKG record to see what the spectra have in common.

WebThe P-wave, PR interval and PR segment. ECG interpretation traditionally starts with an assessment of the P-wave. The P-wave reflects atrial depolarization (activation). The PR interval is the distance between the onset of the P-wave to the onset of the QRS complex.
