摘要

我们描述了一个病人谁接受房室结修改，以创造完整的心脏传导阻滞设置不间断，消融和药物难治性，症状不典型心房扑动。他的双室除颤器（之前植入用于复苏心脏骤停）被编程为VVIR模式，起搏速度更快，为每分钟85次。偶然的是，这个频率几乎是他每分钟250-260次的颤振率的精确阶乘。这导致每6次颤振波在非正常时期下降，导致完全心脏传导阻滞时固定耦合的室上双叉和三叉。将起搏速率重新编程为75bpm，可以消除双音和三叉音。

Serendipitous Supernormality

We describe a patient who underwent AV node modification to create complete heart block in the setting of incessant, ablation-and-drug-refractory, symptomatic atypical atrial flutter. His dual chamber defibrillator (previously implanted for resuscitated cardiac arrest) was programmed to the VVIR mode at a faster pacing rate of 85 bpm. Serendipitously, this rate was an almost exact factorial of his flutter rate of 250–260 bpm. This resulted in every 6th flutter wave falling in the supernormal period, resulting in fixed-coupled supraventricular bigeminy and trigeminy in the setting of complete heart block. Reprogramming the pacing rate to 75 bpm abolished bigeminy and trigeminy.

期刊介绍： The ANNALS OF NONINVASIVE ELECTROCARDIOLOGY (A.N.E) is an online only journal that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients. ANE is the first journal in an evolving subspecialty that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients. The publication includes topics related to 12-lead, exercise and high-resolution electrocardiography, arrhythmias, ischemia, repolarization phenomena, heart rate variability, circadian rhythms, bioengineering technology, signal-averaged ECGs, T-wave alternans and automatic external defibrillation. ANE publishes peer-reviewed articles of interest to clinicians and researchers in the field of noninvasive electrocardiology. Original research, clinical studies, state-of-the-art reviews, case reports, technical notes, and letters to the editors will be published to meet future demands in this field.
