Following atrial fibrillation (AF) ablation procedures, patients may present with atrial tachycardias (ATs) that show remarkable stability for short periods of time but degenerate in unstable forms right afterwards. In order to map these types of ATs, we applied the sequential mapping capabilities only for time segments where ATs exhibited constant cycle length (CL) and activation sequence, excluding the segments with unstable recordings. We herein describe two cases of ATs after AF ablation which were mapped with this technique that allowed for the successful identification and subsequent ablation of the tachycardia circuit.
在心房颤动（AF）消融术后，患者可能会出现房性心动过速（ATs），这些房性心动过速在短时间内表现出显著的稳定性，但随后会退化为不稳定形式。为了标测这些类型的房性心动过速，我们仅对房性心动过速表现出恒定周期长度（CL）和激动顺序的时间段应用顺序标测功能，排除记录不稳定的时间段。我们在此描述两例AF消融术后房性心动过速的病例，这些病例通过该技术进行标测，从而成功识别并随后消融了心动过速环路。
