摘要

一位没有任何合并症的老年妇女，表现为阵发性心悸，并被证明有腺苷反应性狭窄复杂心动过速（NCT）。基线心电图显示窦性心律正常，无预兴奋。心动过速心电图显示有规律的不规则短RP - NCT，频率约为150/min，交替周期长度为320 ms和360 ms，可能的诊断是什么？

Narrow complex tachycardia with cycle length alternans

An elderly lady without any comorbidities, presented with paroxysmal palpitations and was documented to have an adenosine-responsive narrow complex tachycardia (NCT). Baseline electrocardiogram (ECG) showed normal sinus rhythm with no preexcitation. Tachycardia ECG showed a regularly irregular short RP NCT at the rate of around 150/min with alternating cycle lengths of 320 ms and 360 ms.

期刊介绍： The Journal of Electrocardiology is devoted exclusively to clinical and experimental studies of the electrical activities of the heart. It seeks to contribute significantly to the accuracy of diagnosis and prognosis and the effective treatment, prevention, or delay of heart disease. Editorial contents include electrocardiography, vectorcardiography, arrhythmias, membrane action potential, cardiac pacing, monitoring defibrillation, instrumentation, drug effects, and computer applications.
