 * A rapid arrhythmia, causing a disbalance in supply and demand of energy.
-A short period of ischemia causes ''reversibele'' effects: The heartcells will be able to recover. When the ep[isode of ischemia lasts for a longer period of time, heartmuscle cells will die. This is called a '''heart attack''' or '''myocardial infarction'''. That is why it is critical to recognize ischemia on the ECG in an early stage.

-Severe ischemia will reuslts in ECG changes within minutes. While the ischemia lasts, several ECG changes will occur and disappear again. Therefore, it may be difficult to estimate the duration of the ischemia on the ECG, which is crucial for adequate treatment.
