6.6.4 Analyzing High Frequency ECG
In a conventional electrocardiogram, only these ECG signals, of which the amplitude is in the
millivolt range and the frequency is less than 100 Hz, are visible. Those ECG signals, of which
the amplitude is in the microvolt range and the frequency is between 150Hz and 250Hz, are
invisible. If these invisible high frequency components are abnormal, it is the indication of
myocardial ischemia or myocardial infarction.
HF ECG is to detect high frequency components of QRS such as notches, slurs and beadings.
