INTRODUCTION
Cardiac memory refers to T-wave inversions that result when normal ventricular activation resumes following a period of abnormal ventricular activation.
CASE REPORT
We present a case of a 29-year-old man with a pacemaker who presented with new, deep symmetric T-wave inversions caused by cardiac memory.
DISCUSSION
Abnormal ventricular activation is most commonly induced by ventricular pacing but can also occur in the setting of transient left bundle branch blocks, ventricular tachycardia, and intermittent ventricular pre-excitation.
CONCLUSION
Recognition of this phenomenon may help to reduce unnecessary admissions, cardiac testing, and cardiac catheterizations.
引言
心脏记忆是指在一段异常心室激动后恢复正常心室激动时所导致的T波倒置。
病例报告
我们报告一例29岁植入起搏器的男性患者，其出现了由心脏记忆引起的新的、深的对称性T波倒置。
讨论
异常心室激动最常见由心室起搏诱发，但也可发生于短暂性左束支传导阻滞、室性心动过速和间歇性心室预激的情况下。
结论
认识这一现象可能有助于减少不必要的住院、心脏检查和心导管检查。
