Abstract
An implantable medical device, IMD, () is connectable to at least one ventricular lead () having a ventricular basal electrode () and a ventricular apical electrode (). The IMD () comprises a pulse generator () for generating pacing pulses applied to a heart () through the ventricular lead (). The operation of this pulse generator () is controlled by a controller () that is configured to control the pulse generator to first deliver a pacing pulse to the ventricular basal electrode () to stimulate the basal portion of the ventricle () before a pacing pulse is delivered to the apical portion of the ventricle () by the ventricular apical electrode (). This pulse sequence achieves a biologically more correct cardiac stimulation and a contraction pattern that reduces the risk for valvular regurgitation.
