Abstract:
A method of automatically adjusting a pre-ventricular atrial blanking period for use with a cardiac stimulation device, the method comprising:measuring an atrial-ventricular interval as a time interval between an atrial event and an intrinsic ventricular event; measuring a minimum atrial refractory value; determining a maximum pre-ventricular atrial blanking period based on the measured atrial-ventricular interval and atrial refractory value; and decrementing the pre-ventricular atrial blanking period from the maximum pre-ventricular atrial blanking period to a particular value that results in a second of two consecutive atrial events occurring during the pre-ventricular atrial blanking period; and setting the pre-ventricular atrial blanking period to a value based on the particular value.
