Apparatus for treatment of prolonged inter-atrial delay

The method and system for identifying and evaluating the delayed conduction between atriums in a patient are indicated. As for the patient who is identified such and also needs ventricle resynchronization medical treatment, it is possible to rank second and for a measure to be taken by left-atrium pacing and ventricle resynchronization pacing. A measure may be taken by the ventricle resynchronization medical treatment brought about with some patients or the traditionally selected fringe room delay interval without being accompanied by left-atrium pacing again.
