| Prolonged QT interval | Hypocalcemia, some drugs, certain genetic abnormalities |
| Flattened or inverted T waves | Coronary ischemia, hypokalemia, left ventricular hypertrophy, digoxin effect, some drugs |
| Hyperacute T waves | Possibly the first manifestation of acute myocardial infarction, where T waves become more prominent, symmetrical, and pointed |
