Abstract:
1. A heart stimulator for biventricular pacing of a heart, comprising: at least one stimulation pulse generator being connected to or being connectable to a right ventricular or atrial stimulation electrode lead and a left ventricular or atrial electrode lead, respectively, and being configured to generate right chamber stimulation pulses for a right atrium or a right ventricle and left chamber stimulation pulses for a left ventricle or left atrium, respectively, to pace at least a right and a left ventricle or atrium of a heart; a high rate protection unit, being at least indirectly connected to said stimulation pulse generator; said high rate protection unit being configured to trigger a protection time window upon any right or left chamber stimulation pulse, wherein said protection time window has a predetermined duration in time and comprises an early part and a late part immediately following said early part and wherein a total duration of the protection time window corresponds to a time duration between initiating excitation of myocardium and returning of the myocardium to its resting state; wherein said high rate protection unit is further configured to
