His purkinje system
WebThe use of atrial pacing to stress the His-Purkinje system provides further information beyond that of the baseline HV interval. Most normal patients will not exhibit second- or third-degree infranodal block at any time during incremental pacing, particularly at rates less than 150 bpm. Functional infranodal block because of a long-short ...
