    摘要：心电散点图的迭代坐标中隐藏着RR间期的排列组合规律，RR间期的排列组合规律表明常用心电散点图的分层、分形规律符合乘法原理。排列组合规律不仅是散点图命名的依据，也是分析散点图原理的理性思维方式。本文利用排列组合法深度剖析了心房扑动、心房颤动合并起搏心律等特殊病例的散点图形态特征及其形成机制，分析过程不仅体现了时间散点图的一维线性特性、Lorenz散点图的二维平面特性、差值散点图的三维立体特性，而且展现了排列组合的理性思维方式超越“眼见为实”感性思维方式的事实，同时为向量平移法的解析策略做了注脚。

    摘要：病态窦房结综合征多是永久性人工心脏起搏器植入的指征，而动态心电图检查又是起搏器植入前的必检项目之一。心电散点图对RR间期的变化高度敏感，适合快速分析病态窦房结综合征相关的心电大数据。窦房阻滞、窦性暂停、持续性窦性心动过缓等，查看心电散点图便一目了然；相对复杂的慢快综合征、双结病变等，利用时间散点图选时分析也能快速识别与分析。本文精选了五个难易程度不等的病态窦房结综合征病例，对照数学模型剖析并总结了病态窦房结综合征相关的窦性暂停、窦房阻滞、逸搏夺获节律等散点图的特征及其分析技巧。

    摘要：Objective To explore the electrocardiogram (ECG) characteristics, diagnostic clues and occurrence, mechanism of retrograde conduction of the dual atrioventricular nodal pathways(DAVNP).MethodsECG data of 22 patients conforming to the basic characteristics of antidromic DAVNP were retrospectively analyzed. Results The basic rhythm of 22 patients was ectopic rhythm or beats of different nature and origins, among them , there were 10 cases of atrioventricular junctional and ventricular escape rhythm,3 cases premature ventricular contraction, 3 cases of ventricular tachycardia,6 cases of ventricular pacing, Ectopic beats can all form stable and regular Ventriculoatrial retrograde conduction of intermittent Ventriculoatrial retrograde conduction,which shows a certain degree of reproducibility. The ectopic QRS wave was followed by related retrograde P wave (P-), 10 patients showed two forms of P-, 9 patients showed a single form, and 3 patients could not be determined. There were two or more RP- interphase, with the difference greater than 0.06 s, and the maximum difference between the two RP- interphase was 0.11~0.44 (On average 0.24±0.09). There were 12 cases with ventricular echo beat (reciprocal beat), 3 cases showed wenckebach ventriculoatrial conduction, 2 cases formed 1∶2 ventriculoatrial antidromic conduction, and 1 case showed fast and slow AVNRT. Conclusions Retrograde Ventriculoatrial conduction via DAVNP is a relatively rare electrophysiological manifestation. Diagnostic analysis and preliminary diagnosis.can be made by observing ECG characteristics. To provide a strong theoretical basis for further cinical diagnosis and treatment.

    摘要：His-Purkinje system, damaged or in a pathological state, may exhibit a unique electrocardiographic phenomenon known as inverse decremental conduction (also referred to as Yan conduction): within a certain frequency range, the conduction velocity at the damaged site of His-Purkinje system shows a proportional correlation with the upstream stimulation frequency. To date, case reports of inverse decremental conduction have primarily been observed following transcatheter aortic valve replacement (TAVR) and transcatheter ventricular septal defect closure procedures. This association likely stems from surgical-induced factors such as direct mechanical stimulation, edema, inflammation, or localized hematoma damaging specific regions of His-Purkinje system. This paper systematically reviews the potential mechanisms, electrocardiographic manifestations, and clinical significance of inverse decremental conduction through three relevant cases (two secondary to TAVR and one potentially related to degenerative or ischemic changes in His-Purkinje system).
