    摘要: Heart stimulator that stimulates at least a heart's right atrium and ventricle in an atrium asynchronous stimulation mode with an overdrive stimulation rate. Interposes one resynchronization cycle after a sensed atrial event to regain AV synchrony during otherwise asynchronous stimulation mode. Allows for pacing mode that can pace the atrium with an overdrive stimulation rate in dual-chamber asynchronous mode while maintaining the AV synchrony and is called DDI(R)+. In DDI(R)+, pacemaker performs an atrial asynchronous (V synchronous) pacing mode such as DDI or DDI(R). The overdrive stimulation rate (OSR) is either a fixed rate (programmed by the external device) that is thought to be above the underlying intrinsic atrial rate, or is dynamically adjusted according to the measured atrial cycle length to be slightly above intrinsic atrial rate. The overdrive stimulation rate may be based on an intrinsic atrial rate or on hemodynamic need. DDI(R)+ timing may be ventricle-based.

    摘要: 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.
