晚近,细胞电生理学的进展提出了冲动的相加及其在各种心律失常中的作用;因此,有必要澄清“相加”与“融合”的概念以免混淆。本文将首先讨论融合波的定义和冲动相加现象,然而再列举在各种情况下出现的融合波。融合波的定义和冲动相加现象 More recently, advances in cellular electrophysiology have proposed the addition of impulsivity and its role in various arrhythmias; therefore, it is necessary to clarify the concept of “addition” and “fusion” to avoid confusion. This article will first discuss the definition of fused waves and the imposition of impulsivity, however, again to enumerate the fusion waves that emerge under various circumstances. The definition of the fusion wave and the impulse addition phenomenon
