摘要： Conduction block across a lesion in tissue can be assessed by applying a pacing signal to tissue on one side of the lesion and sensing electrophysiological activity in the tissue on the opposite side of the lesion. A signal processor, such as may be incorporated into an electroanatomical mapping system, analyzes the sensed electrophysiological activity for a response evoked by the pacing signal and outputs an indicator of conduction block status. More particularly, when a preset number of consecutive pacing pulses do not yield an evoked response, an indicator of block can be output; conversely, when a preset number of consecutive pacing pulses do yield an evoked response, an indicator of no block can be output
