Figure 1. – Left: a hand-shaped stylet guiding the positioning of the RV lead in the uupermost proximal third of the interventricular septum for para-Hisian pacing. Center: Operator (ADLF) showing a comparison of the shape obtained by molding the guide wire with the curvature of one of the pre-molded sheaths available in Brazil (C315His Medtronic™). Right: fluoroscopy (left oblique projection) showing the final position of the lead in the right ventricle. Note the angulation of the tip, which is perpendicular to the spine. Adapted from12,19.
