Based upon experiences with 14 patients the clinical feasibility of transmediastinal retrocardial stimulation of the heart, of the left atrium as well as in one case of the left ventricle, is reported. Principally both can be stimulated by thus introduced pacemaker electodes. Thus on the one hand thresholds and consequently pulse effectivity appear to be a function of the electrode distance from the myocardium, whilst on the other hand the transmediastinal retrocardial thresholds are initially rather high in analogy to the majority taken from the atrial endocardial surface. Nevertheless, the transmediastinal retrocardial technique is possibly applicable for permanent cardiac pacing. However, additional tests about this are still necessary.
基于对14例患者的经验，报告了经纵隔心后区刺激心脏、左心房以及1例左心室的临床可行性。原则上，通过这样引入的起搏器电极两者均可被刺激。因此，一方面阈值以及由此产生的脉冲有效性似乎是电极与心肌距离的函数，而另一方面，与大多数取自心房心内膜表面的情况类似，经纵隔心后区阈值最初相当高。尽管如此，经纵隔心后区技术可能适用于永久性心脏起搏。然而，关于这一点仍需进行额外测试。
