Towards a QT driven AV delay?

During the last few years, cardiac stimulation has evolved in parallel with ablative techniques towards a sophistication allowing its application to various new pathologies. The programming of these new stimulators is becoming more and more complex. Nevertheless, the programming of the AV delay (AVD) remains one of the fundamental points in the adjustment of dual chamber pacemakers and there is a certain revival in the optimization of the AVD by new methods.
