2012年6月30日 · S1Q3T3 pattern means the presence of an S wave in lead I (indicating a rightward shift of QRS axis) with Q wave and T inversion in lead III. S1Q3T3 pattern is the classical ECG pattern of acute pulmonary embolism which is often taught in ECG classes, though it is not the commonest ECG finding in pulmonary embolism.

2024年10月8日 · Simultaneous T wave inversions in the inferior (II, III, aVF) and right precordial leads (V1-4) is the most specific finding in favour of PE, with reported specificities of up to 99% in one study. T-wave inversion is commonly associated with acute coronary syndrome (ACS).

2020年4月17日 · 肺型p波：右房压力增高和右房扩大。 s1q3t3（图4、5）：反应的依然是右室劳损和压力增高，但敏感性和特异性均比较低。 房性心律失常：房扑和房颤，和右房右室扩大、低氧等均有关系。 非特异性st-t改变：敏感性高，特异性差。

This case report highlights a patient with an acute “saddle” PE exhibiting a distinct pattern on electrocardiogram (ECG) associated with submassive PEs known as S1Q3T3. Although these and other electrocardiographic changes associated with PE have been well documented, corroboration in the clinical setting remains elusive.

2020年7月24日 · S1Q3T3 pattern is classically described in a case of massive PTE that seems to occur in 54% of cases and has high specificity. 1,2 A combination of S1Q3T3 and Palla’s sign is rare, but the early interpretation by the emergency physician can raise suspicion for PTE.

2024年5月29日 · 肺栓塞心电图s1q3t3是一种特定的心电图图形，反映了急性右心室扩张，qrs初始向量向右上偏移的现象。 S1Q3T3图形的出现可能与左后分支缺血、一过性左后分支传导阻滞有关。

2021年7月28日 · S1Q3T3 on electrocardiogram, a diagnostic clue for pulmonary thromboembolism QJM. 2021 Jul 28;114(4):278-279. doi: 10.1093/qjmed/hcaa231. Authors N Arora 1 , D P Dhibar 1 Affiliation 1 Department of Internal medicine, Post Graduate ...

Chest computed tomography showed bilateral PEs with right heart strain (RHS), resulting in initiation of a heparin infusion. Computed tomography angiogram showed bilateral exten-sive PEs with opacities in the main pulmonary artery and bilateral lobar arteries (saddle PE) with RHS.

2016年9月1日 · ECG findings in patients with PE have been described since 1935. It has been extrapolated that “S1Q3T3” is a sign of right ventricular change secondary to occlusion of the pulmonary vascular system. Spontaneous resolution of changes demonstrates one example of an ECG’s potential variation.
