Abstract
Marked variability in the amplitude or polarity of pacemaker artifacts may be a clue to generator malfunction or partial electrode fracture. We report a case where "pacemaker spike alternans" occurred factitiously as a result of a digital "roll-over" effect. The widespread introduction of digital electrocardiographs into clinical practice makes recognition of such artifacts important.
摘要
起搏器伪差的幅度或极性存在明显变化可能提示发生器故障或电极部分断裂。我们报告一例因数字“翻转”效应人为造成“起搏器尖峰交替现象”的病例。数字心电图在临床实践中的广泛应用使得识别此类伪差变得很重要。
