A 62-year-old male patient was admitted with regular wide QRS complex tachycardia. After ajmaline administration, the heart rate slowed down disclosing atrial flutter with variable QRS morphologies. Electrocardiography after conversion to sinus rhythm showed narrow QRS complexes. Decremental atrial stimulation during electrophysiological study caused progressive pre-excitation. Spontaneously, typical atrial flutter occurred with pre-excited QRS complexes. Both accessory pathway and atrial flutter were ablated in the same session.
一位 62 岁男性患者因规则宽 QRS 复合性心动过速入院。给予阿马林后，心率减慢，揭示出具有不同 QRS 形态的心房扑动。窦性心律转复后的心电图显示为窄 QRS 复合波。电生理研究中的递减性心房刺激引起进行性预激。心动过速时，出现典型的预激性 QRS 复合波，提示预激旁路及心房扑动同时存在。在同一次手术中对旁路和心房扑动进行了消融。
