Abstract:
Objective To evaluate a noninvasive method which has been applied on human subjects to observe beat to beat activity of the His bundle potential. Methods Recording was performed with very low noise, high gain amplifiers and by analog filtering. 3-brigade amplifiers and 16-bite A/D were connected to a microcomputer by USB. The signal was processed by a combined pattern recognition and digital filtering software. Results The results of surface monitoring were compared with intracardiac method in 30 patients. The results of non-invasive method were consistent with that interventional method. A prominent waveform was observed between the atrial and ventricular complexes (A, H, V waves), and corresponded to His bundle activity in all patients. Conclusion The noninvasive method of beat to beat surface recording of His bundle activity has broad clinical applicability and high utility for the patients with latent A-V block and eletrophysiologic study.
