A 36-year-old pregnant woman (20 weeks) was admitted to the coronary care unit because of ventricular tachycardia (VT). 12-Lead electrocardiogram showed a monomorphic regular wide QRS tachycardia with a ventricular rate of 220 beats/min and left bundle branch block morphology. Her electrocardiogram after the termination of the tachycardia returned to baseline with the Twave inversions in V1-V6 and DII, DII, aVF. The marked T-wave inversions demonstrate cardiac memory due to the preceding abnormal ventricular activation caused by VT. Because the T-wave inversion happened after the conversion from VT to sinus rhythm, it may be explained by the cardiac memory phenomenon.
一名36岁孕妇（孕20周）因室性心动过速（VT）入住冠心病监护病房。12导联心电图显示为单形性规则宽QRS心动过速，心室率为220次/分钟，呈左束支传导阻滞形态。心动过速终止后的心电图恢复至基线，但V1-V6、DII、DIII、aVF导联出现T波倒置。显著的T波倒置表明存在心脏记忆，这是由之前VT导致的异常心室激动引起的。由于T波倒置发生在从VT转为窦性心律之后，可能是由心脏记忆现象所解释。
