ST segment and T wave changes are the most common ECG abnormalities. Interpretation must be correlated with other clinical and laboratory information to avoid overestimating or underestimating their significance. Classic causes include left ventricular hypertrophy, digitalis glycosides, and ischemic heart disease. Notched or bifid T waves have been reported in a variety of syndromes. In the geriatric population, they are most commonly associated with psychoactive drugs or CNS disorders.
ST段和T波改变是最常见的心电图异常。解读必须与其他临床和实验室信息相关联，以避免高估或低估其意义。典型病因包括左心室肥厚、洋地黄苷和缺血性心脏病。在多种综合征中均有报道出现切迹或双峰T波。在老年人群体中，它们最常与精神活性药物或中枢神经系统疾病相关。
