Abstract:
Objective To investigate the application of open beat to beat techniques recording His bundle activity without digital averaging. 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 pattern recognition plus digital filtering software. The subjects were in a supine position during the recording. Results A prominent waveform was observed between the atrial and ventricular complexes and corresponded to His bundle activity in 46 volunteers. Recordings in 8 patients were compared with records obtained by intracardiac electrode, and a good conformation was seen. 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.
