ST and T changes occur when a problem in ventricular depolarization causes a problem with repolarization.
•ECG findings:
•Diffuse process.
•Generally involves both the ST and T waves.
•T wave axis is opposite from the QRS axis.
•Typical examples:
•Left ventricular hypertrophy, left bundle branch block, others.
•Primary ST and T changes can occur on top of secondary changes.
