Implantable medical device for cardiac therapy

An implantable medical device for delivering cardiac therapy to a heart of a subject comprising:

• a lead connector having a first terminal electrically connectable to a first electrode terminal of at least one cardiac lead and a second terminal electrically connectable to a second electrode terminal of said at least one cardiac lead, said at least one cardiac lead having a ventricular basal electrode electrically connected to said first electrode terminal and being adapted for implantation in connection with a basal portion of a ventricle of said heart and a ventricular apical electrode electrically connected to said second electrode terminal and being adapted for implantation in connection with an apical portion of said ventricle;
• a pulse generator connected to said lead connector and configured to generate pacing pulses;
• and
• a controller connected to said pulse generator and configured to control said pulse generator to deliver a pacing pulse to said first terminal followed by a pacing pulse to said second electrode terminal during a cardiac cycle.
