Overview
Electrocardiogram
The ECG findings are often confused with those of an acute anterior wall myocardial infarction.[1][2] Findings on ECG include:[2][3]
- ST elevation in the precordial leads
- T wave inversion
- Q wave formation
- QT prolongation
- Rarely, malignant ventricular arrhythmias may be seen
