患者女,40岁,农民。因心前区剧烈疼痛伴出冷汗24小时,急诊入院。临床诊断:急性前间壁心肌梗塞,心律失常。在V_2、V_1、V_4导联可见S-T段抬高弓背向上的单项曲线,T波倒置。V_2、V_3可见病理性Q波。入院第3天,出现心律失常。心电图分析:连续描记Ⅱ导联,P波顺序发生,P-P间期不等,形态不一。P-P间期0.66秒～0.68秒,房率71～90次/分。在P_1,P_2、P_3、P_4、P_5、P_8、P_(17)、P_(21)、P_(22)、P_(23)、P_(21)、P_(25)均为正波。P′_(10)、P′_(11)、P′_(12)、
Female patient, 40 years old, farmer. Due to precordial pain accompanied by cold sweat 24 hours, emergency admission. Clinical diagnosis: acute anterior myocardial infarction, arrhythmia. In the V_2, V_1, V_4 leads visible S-T segment elevation bow single curve, T wave inversion. V_2, V_3 visible pathological Q waves. On the third day of admission, arrhythmia occurred. ECG analysis: continuous tracing II lead, P wave sequence occurred, P-P interval ranging from different shapes. P-P interval of 0.66 seconds to 0.68 seconds, the room rate of 71 to 90 beats / min. The P_1, P_2, P_3, P_4, P_5, P_8, P_17, P_21, P_22, P_23, P_21, P_25 are all positive waves. P ’_ (10), P’ _ (11), P ’_ (12),
