Cardiac memory is a process where the ECG does not immediately change to back to baseline after a period of arrhythmia or pacing. Mostly altered T waves are seen on the ECG. Cardiac memory is frequently induced by ventricular pacing or arrhythmias and historically has been considered of minor relevance to medical practice, although it is debated whether this is justified. The T-wave changes that occur during cardiac memory can resemble the inversions that occur after myocardial infarction.
