Relationship between demand pacemaker sensitivity and cardiac diastolic cycle

Abstract

Jpn. J. Artif. Organs 11 (3), 804-806 (1982) From the electromechanical standpoint, sensitivity of demand pacemaker is essentially equal during its nonrefractory period. Authors observed, however, QRS waves in the early diastolic phase is easily sensed by the demand pacemaker, though QRS in the late diastolic phase is poorly sensed. The sensitivity of demand pacemaker resulted in showing the highest in its earliest phase and the lowest in its latest period.
