Measure PQ interval at A Sense
When the 150 msPQ interval is less than 150 ms, the PQ interval is -40 ms, the LV preceding 30 ms
When the PQ interval is 150 ms to 200 ms, the PQ interval is -50 ms, the LV preceding 30 ms
When the PQ interval is 200 ms or more, set PQ interval 120 ms, LV-RV simultaneous pacing.
This study is a crossover study for 3 months, after 3 months we change the setting from 1 group to 2 groups and finish in 6 months.
Set AV delay by cardiac ultrasound examination and set VV delay to 0 ms.
