The clinical course of a newborn can be rendered more complex by the sudden development of a disturbance in heart rhythm and conduction. The caregiver's ability to recognize a particular dysrhythmia and its most probable mechanism is crucial for optimal management. During the past 15 years, there has been significant progress in the understanding of the electrophysiologic basis of rhythm disturbances in the newborn period. This understanding has led to more precise diagnosis and effective treatment regimens for infants with dysrhythmias. Using recent case studies from one intensive care nursery as illustrations, this article discusses the clinical presentation and electrophysiologic mechanisms of three common forms of rhythm and conduction disturbance. The discussion pertains to disturbances of rhythm in association with tachycardia only. Emphasis is placed on the electrocardiographic diagnosis and clinical management of these infants.
新生儿期心律失常和传导障碍的突然出现会使新生儿的临床病程变得更为复杂。护理人员识别特定心律失常及其最可能机制的能力对于优化治疗至关重要。在过去15年里，对新生儿期心律失常的电生理基础的认识有了显著进展。这一认识为心律失常患儿带来了更精确的诊断和有效的治疗方案。本文以一家重症监护病房近期的病例研究为例，讨论了三种常见的节律和传导障碍的临床表现及电生理机制。讨论仅涉及与心动过速相关的节律紊乱。重点是这些婴儿的心电图诊断和临床管理。
