<p>Implantable heart stimulator comprising an AV-interval generator adapted to generate a variable AV-interval and provided with a predetermined basic AV-interval. The heart stimulator further comprises a counter that counts the number of times the AV-interval is changed in response of a fusion avoidance algorithm or a stimulation threshold search algorithm during a predetermined time period, e.g. 1-3 minutes, wherein the basic AV-interval is changed if said number of times is greater than a predetermined value, e.g. 4-10.</p> |
