SUMMARY
The discussion focuses on the frequency content of the QRS complex in electrocardiogram (ECG) signals. The QRS complex, which represents the depolarization of the ventricles, lasts approximately 70–110 milliseconds and exhibits the highest amplitude among ECG waveforms. Its steep slopes result in a frequency concentration predominantly within the 10–40 Hz range, indicating that high-frequency signals change rapidly, which is crucial for accurate ECG interpretation.
