Disclosed herein are a variety of implantable medical leads for coupling to an implantable pulse generator and targeted stimulation of the lateral and posterior basal left ventricular region of a patient heart. As one example, the lead may include a tubular body including proximal section, an intermediate section and a distal section. The intermediate section biases into a generally S-shaped or sinusoidal-shaped configuration when the intermediate section is in a free or non-restricted state. The proximal section proximally extends from the intermediate section to a proximal end configured to electrically couple to the implantable pulse generator. The distal section biases into a generally straight linear shaped configuration when the distal section is in a free or non-restricted state.
