The relative merits of unipolar and bipolar systems are reviewed in the context of DDD pacing. In order to allow reliable atrial sensing in the presence of myopotentials and exogenous noise, bipolar atrial sensing is desirable. Bipolar ventricular sensing will reduce the incidence of myopotential sensing and may reduce susceptibility to cross-talk. Unipolar systems, however, generally offer better stimulation characteristics. Considerations have led to the development of a new DDD pacemaker with bipolar sensing and unipolar pacing characteristics. The bipolar-sense/unipolar-pace pulse generator is simple to implement based upon a unipolar design and retains the simplicity, convenience, and reliability inherent in that mode.
在DDD起搏的背景下，对单极和双极系统的相对优点进行了综述。为了在存在肌电位和外源性噪声的情况下实现可靠的心房感知，双极心房感知是可取的。双极心室感知将降低肌电位感知的发生率，并可能降低串扰的易感性。然而，单极系统通常具有更好的刺激特性。基于这些考虑，开发了一种具有双极感知和单极起搏特性的新型DDD起搏器。双极感知/单极起搏脉冲发生器基于单极设计易于实现，并保留了该模式固有的简单性、便利性和可靠性。
