The diagnosis of right ventricular perforation by an endocardial pacemaker electrode should be suspected when failure of pacing occurs without electrode displacement. Although a number of changes occur on the standard electrocardiogram (ECG), none of these are diagnostic. The intracardiac electrogram performed during electrode withdrawal is not only diagnostic of perforation but can also aid in electrode positioning. Two case reports highlight these changes in the intracardiac electrogram. The first case also illustrates that, with electrode perforation, the ability to sense the intrinsic intracardiac electrical activity may be retained.
当起搏失败且电极无移位时，应怀疑心内膜起搏器电极导致右心室穿孔。尽管标准心电图（ECG）会出现一些变化，但这些变化均无诊断意义。电极回撤过程中进行的心内心电图不仅可诊断穿孔，还能辅助电极定位。两篇病例报告突出了心内心电图的这些变化。首例病例还表明，电极穿孔时，感知心内固有电活动的能力可能得以保留。
