Cardiac arrhythmias are an important aspect of fetal and neonatal medicine. Premature complexes of atrial or ventricular origin are the main cause of an irregular heart rhythm. The finding is typically unrelated to an identifiable cause and no treatment is required. Tachyarrhythmia most commonly relates to supraventricular reentrant tachycardia, atrial flutter, and sinus tachycardia. Several antiarrhythmic agents are available for the perinatal treatment of tachyarrhythmias. Enduring bradycardia may result from sinus node dysfunction, complete heart block and nonconducted atrial bigeminy as the main arrhythmia mechanisms. The management and outcome of bradycardia depend on the underlying mechanism.
心律失常是胎儿和新生儿医学的一个重要方面。房性或室性起源的早搏复合体是心律不齐的主要原因。这一发现通常与可识别的病因无关，无需治疗。快速心律失常最常见的是室上性折返性心动过速、心房扑动和窦性心动过速。有几种抗心律失常药物可用于围产期快速心律失常的治疗。持续性心动过缓可能由窦房结功能障碍、完全性心脏传导阻滞和未下传的房性二联律作为主要心律失常机制引起。心动过缓的处理和预后取决于潜在机制。
