| Abstract: | Objective] To explore the influence of catheter inter-electrode space on the in vivo His electrograph recordings in rabbits. [Methods] Thrity-three rabbits were instrumented by two type of catheter with different inter-electrode space, from the left common carotid artery into the hearts to record the in vivo His electrograph. The inter-electrode space in catheter A was 2 mm; catheter B 5 mm. [Results] The successful rate of recording by catheter A was 93.33%; catheter B 60.00%; P <0.005. [Conclusion] The successful rate of in vivo recording by catheter A is significantly higher than that by catheter B. |
