A 23‐year‐old athlete with symptomatic low burden premature ventricular contraction ( PVC ) with left bundle branch block morphology and inferior axis morphology was sent to our department for RV mapping and PVC ablation. Exit zone of the PVC was easily and clearly defined by the bipoles A3‐A4 achieving optimal and detailed pacemapping (Panels A‐C) near the His bundle (yellow dots). The spatial conformation and the smooth shape of the catheter would definitely help everyday procedures in the setting of low burden PVC /noninducible focal ventricular arrhythmia, especially when the focus is located very close to the conductive tissue.
