At the time of<unk>  implantation, AV synchrony should be optimized to prevent the occurrence of<unk><unk> .
Make sure that appropriate<unk>  is implanted in the patient to avoid loss of AV synchrony. For example:
AAI or a DDD<unk>  maintains AV synchrony. Result of AV synchrony is increase in cardiac output. So AAI or DDD<unk>  should be given to patients who has sinus rhythm.
AAI or a DDD<unk>  maintains AV synchrony. Result of AV synchrony is increase in cardiac output. So AAI or DDD<unk>  should be given to patients who has sinus rhythm.
Patients with optimized AV synchrony have shown great results of implantation and very low incidence of<unk><unk>  than those with suboptimal AV synchronization.
