1. A heart stimulator for left-ventricular pacing comprising:

  • a left ventricular stimulation pulse generator connected or connectable to a single left ventricular electrode lead adapted to be placed for left ventricular stimulation and having one or more electrodes for delivery of stimulation pulses to left ventricular myocardial heart tissue, said left ventricular stimulation pulse generator adapted to generate and deliver stimulation pulses of switchable polarity; and

    ,a control unit connected to said left ventricular stimulation pulse generator and adapted to control said left ventricular stimulation pulse generator totrigger generation and delivery of stimulation pulses having a polarity controlled by said control unit, and todeliver at least a pair of supra-threshold stimulation pulses of opposite polarity.
