From: Permanent left bundle branch area pacing utilizing intracardiac echocardiogram
Intracardial echocardiography views obtained with the catheter in the RV. a: Short axis view of the septum around the mitral valve plane. The distance between the implantation site and the front junction point and the distance between the implantation site and the back junction point should be measured. b: Longitudinal view of the septum. The distance from the implantation site to the apex and the distance from the implantation site to the tricuspid annulus should be measured. RV, right ventricle; LV, left ventricle; V, transducer location; IVS, interventricular septum; 5, distance to the transducer; PPL, permanent pacing lead; TPL, temporary pacing lead; short arrow, lead tip; long arrow, implantation site
