In a 12-year-old girl with history of recurrent palpitation, an ambulatory 24 h Holter electrocardiogram showed a wide QRS complex rhythm with atrioventricular dissociation. During an electrophysiology study, an atriofascicular pathway was diagnosed with an inducible antidromic atrioventricular re-entrant tachycardia. At slower heart rates, the patient had a wide QRS complex escape rhythm similar to the tachycardia and the pre-excited QRS complex morphology. This indicates the presence of pacemaker-like cells in the atriofascicular accessory pathway giving rise to the wide QRS complex escape rhythm at a slower heart rate.
一名有反复心悸病史的12岁女孩，24小时动态心电图显示宽QRS波群心律伴房室分离。在电生理研究中，诊断为房室旁路并诱发了逆向型房室折返性心动过速。在心率较慢时，患者出现与心动过速及预激QRS波群形态相似的宽QRS波群逸搏心律。这表明房室旁路中存在类似起搏细胞，在心率较慢时引发宽QRS波群逸搏心律。
