Abstract

The incidence and mortality rates of acute pulmonary embolism (APE) are high in clinical emergencies, making early diagnosis and risk stratification crucial. Electrocardiogram (ECG) plays a significant role in guiding the diagnosis and differential diagnosis of pulmonary embolism. Acute pulmonary embolism can present with various ECG manifestations. The presence of pulmonary hypertension and increased right ventricular load in pulmonary embolism can lead to T wave inversion in the right cardiac lead. Additionally, some patients may exhibit a prolonged QT interval, which is associated with the pathophysiological processes resulting from both pulmonary hypertension and myocardial ischemia.

摘要

急性肺栓塞（APE）在临床急症中的发病率和死亡率较高，因此早期诊断和风险分层至关重要。心电图（ECG）在指导肺栓塞的诊断和鉴别诊断中发挥着重要作用。急性肺栓塞可表现出多种心电图表现。肺栓塞中肺动脉高压和右心室负荷增加可导致右心导联T波倒置。此外，一些患者可能表现出QT间期延长，这与肺动脉高压和心肌缺血所导致的病理生理过程有关。
