This case demonstrates that an immediate superior vena cava (SVC) conduction block may occur during pulsed field ablation (PFA) due to anatomical proximity, a positive tissue proximity index, and a narrow SVC diameter. However, lesions not directly influenced by PFA tend to regress and may be reversible, leading to SVC potential reconduction.

该病例表明，由于解剖位置接近、组织接近指数为正以及上腔静脉（SVC）直径狭窄，在脉冲场消融（PFA）期间可能会立即发生上腔静脉传导阻滞。然而，未受PFA直接影响的病变往往会消退且可能是可逆的，从而导致SVC电位再次传导。CS，冠状窦；d，远端；LAO，左前斜位；LL，左侧位；p，近端；PA，正位；RA，右心房；RAO，右前斜位；RSPV，右上肺静脉；RV，右心室；SUP，上视图。
