METHOD AND APPARATUS FOR REMOVING BASELINE WANDER FROM AN ECG SIGNAL |
摘要 |
<p>According to one aspect of the invention, an improved ECG monitor includes a plurality of electrodes to be affixed to a patient's body to pick up ECG signals in an ECG signal band. The electrodes are electrically coupled to a plurality of input amplifiers. At least one analog to digital converter ("ADC") is electrically coupled to the input amplifiers to digitize the ECG signals. A digital baseline wander filter has an internal finite impulse response ("FIR") low pass filter characterized by a substantially trapezoidal impulse response. The baseline wander filter substantially removes a baseline wander signal component having a range of frequency components below the ECG signal band. The ECG waveform output signal is a baseline filtered ECG waveform representing the one or more of the ECG signals. The ECG waveform output signal from the improved ECG monitor is delayed less than 2 seconds from the ECG signals.</p> |
