Abstract
The invention relates to heart stimulators and implantable atrial pacemakers which utilize a rhythm based atrial capture threshold test wherein in a ventricle based DDI mode a predetermined number of ventricle started atrial and ventricular escape intervals are triggered with an overdrive rate about 20% higher than an intrinsic heart rate. The number of atrial sense events during atrial capture threshold test is counted. Too high of a number of atrial sense events indicates loss of capture due to too small of a pulse strength of the atrial stimulation pulses.
