Abstract:
The spectrums of intracardiac electrograms, QRS complex wave and T wave which were picked up at the position where pacing electrode is to be located in the endocardia were investigated. Simultaneously, a variety of pacemaker sensitivity testing waves and the load capacities of two kinds of pacing electrode were analysised by a spectral analysis method. The results show that the sp(?)ctral distributions of intracardiac electrograms are below 70Hz, the T waves have lower spectral distributions and the QRS complexs have higher ones, indicating that the frequency band of the QRS wave detection circuit should be 8-45 Hz. The advantages and shortcomings of conventional pacemaker sensitivity testing waves and the load capacities of the pacing electrodes are discussed.
