Atrial fibrillatory rate (AFR) can predict outcome of interventions for atrial fibrillation (AF); however, AFR behavior at AF onset in humans is poorly described. We studied AFR during spontaneous AF episodes in patients with lone paroxysmal AF who received implantable loop recorders and had AF episodes of 1 hour or more recorded (n = 4). Mean AFR per minute was assessed from continuous implantable loop recorder electrocardiogram using spatiotemporal QRST cancellation and time-frequency analysis. Atrial fibrillatory rate increased from 290 ± 20 to 326 ± 39 fibrillations per minute during the first 3 hours (P<.05) and reached plateau then. Atrial fibrillatory rate beyond the initial 3 hours can, therefore, be considered stable and may be evaluated for prediction of intervention effect.
心房颤动率（AFR）可预测心房颤动（AF）干预的结果；然而，人类房颤发作时AFR的行为描述甚少。我们对接受植入式环路记录仪且记录到1小时或更长时间房颤发作的孤立性阵发性房颤患者的自发性房颤发作期间的AFR进行了研究（n = 4）。使用时空QRST消除和时频分析，从连续植入式环路记录仪心电图评估每分钟的平均AFR。在前3小时内，心房颤动率从每分钟290±20次增加到326±39次（P<0.05），然后达到平台期。因此，最初3小时后的心房颤动率可被视为稳定，可用于评估干预效果的预测。
