Myocardial infarction affects ventricular repolarization and/or depolarization, often producing ST elevation. Similarly, any condition that affects ventricular repolarization and/or depolarization may also produce ST elevation. Some of these conditions include:

• Left Ventricular Hypertrophy
• Left Bundle Branch Block
• Ventricular Rhythms
• Benign Early Repolarization
• Pericarditis
• Hemmorhagic Stroke
• Pulmonary Embolism
• Aortic Dissection
• Brugada Syndrome
• Hypothermia
• Hyperkalemia
• Coronary Vasospasm
• Ventricular Aneurysm
• Paced rhythm
