人类房颤的非侵入性标测简介：心房颤动（AF）的侵入性高密度标测揭示了不同的心房激活模式，从单波前到多个同时波前的无序激活。是否类似的激活模式，也可以观察到使用体表记录是目前未知的，因此在本study.Methods和结果进行评估：表面心电图映射进行了14例（年龄68 +/- 14岁）与持续性房颤（房颤持续时间12 +/- 18个月）。共56个心电图导联被放置在胸前心房上方的前面（n = 40）和后面（n = 16）。使用240秒的记录，波前传播图被自动计算，并视觉上分为I型（单波前），II型（单波前与波断裂和分裂），或III型（多个同时波前）。几乎一半的患者（n = 6）主要表现为III型心房激动，而6例患者主要表现为I型激动。其余患者（n = 2）表现为I型和III型混合激活。这种分类显示出高度可重复性超过4 minutes.Conclusions：使用心电图体表标测AF期间，心房激动的个体差异可以观察到。AF期间的表面活化图案显示出优异的短期再现性。（J.E.

Noninvasive Mapping of Human AF.Introduction: Invasive high-density mapping of atrial fibrillation (AF) has revealed different patterns of atrial activation ranging from single wavefronts to disorganized activation with multiple simultaneous wavefronts. Whether or not similar activation patterns can also be observed using body surface recordings is currently unknown, and was consequently evaluated in this study.Methods and Results: Surface electrocardiographic mapping was performed in 14 patients (age 68 +/- 14 years) with persistent AF (AF duration 12 +/- 18 months). A total of 56 electrocardiographic leads were placed on the chest over the atria on the front (n = 40) and on the back (n = 16). Using 240-second recordings, wavefront propagation maps were automatically computed and visually classified as either type I (single wavefront), II (single wavefront with wave breakages and splitting), or III (multiple simultaneous wavefronts). Almost half of the patients (n = 6) presented most predominantly type III atrial activation, while six patients mostly presented type I activation. The rest of the patients (n = 2) presented mixed type I and type III activations. This classification showed to be highly reproducible over 4 minutes.Conclusions: Using electrocardiographic body surface mapping during AF, interindividual differences of atrial fibrillatory activation can be observed. The surface activation pattern during AF shows an excellent short-term reproducibility.(J Cardiovasc Electrophysiol, Vol. 20, pp. 507-513, May 2009).
