Abstract:

BACKGROUND: The evenness and directivity of electric field are two important indexes in endocardial three-dimensional mapping technology. The factors that impact the indexes are electric poles and mediator. Therefore, analyzing the influence of the factors on the electricity field is significant.
OBJECTIVE: To analyze the effects of poles size and distance on the performance of conduction field.
METHODS: The influences of pole parameters were analyzed through simulation and experiment. In a singleness mediator, through alternating the pole parameters step by step, the field voltage was measured and then the evenness index and directivity index were calculated.
RESULTS AND CONCLUSION: The results indicated that the evenness index and directivity index got perfect when the size and distance of poles become large. When the poles are as large as the size of measure area, the evenness index is 0.017, which can satisfy the accuracy.
