1. A method of implanting pacing lead in a patient's heart, the method comprising:
inserting a catheter through coronary sinus ostium of the patient's heart;
moving the catheter to position a distal end region of the catheter into the great cardiac vein past the anterolateral vein of the patient to one or more positions proximate at least one septal perforating vein of the patient;
injecting contrast out of the distal end region of the catheter into an injection area of each of the one or more positions proximate the at least one septal perforating vein;
identifying an implant region proximate the at least one septal perforating vein;
removing the catheter; and
moving a pacing lead to the implant region to deliver pacing therapy thereto.
