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 · SI QIII TIII pattern – deep S wave in lead I, Q wave in III, inverted T wave in III (20%). This “classic” finding is neither sensitive nor specific for PE.

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.

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.

2023年5月31日 · S1Q3T3是肺栓塞特征性心电图的表现，S1Q3T3即在12导联心电图1导S波变深>1.5mm，3导出现深的q波和T波倒置，T波在V1-V4导联倒置，大约只有30%的肺栓塞患者会出现S1Q3T3的心电图表现。 肺栓塞是血栓进入肺动脉及其分支，引起肺动脉堵塞导致的临床疾病，常见是血栓引起肺动脉栓塞，肺动脉栓塞患者表现为胸闷、胸痛、呼吸困难、晕厥，有的表现为休克，其症状多样，容易发生漏诊。 子宫肌瘤的变性可分为多种，主要是波量变、狼性变、红色 …

The most common ECG finding in the setting of a pulmonary embolism is sinus tachycardia. However, the “S1Q3T3” pattern of acute cor pulmonale is classic; this is termed the McGinn-White Sign. A...

其发生率约15％～25％，在著名的尿激酶肺栓塞试验（upet）中仅发现12％～50％，我院为61.5％。该图型的特征是第1导联出现s波或s波变深，第iii导联出现q波和t波倒置（图6）。q3t3图型也可扩展到avf导联，也可合并下壁st段轻度抬高。

S1Q3T3 Pulmonary Embolism ECG/EKG Classic Pattern is the finding that indicates right sided heart strain (acute cor pulmonale). S1Q3T3 Pattern is called classic EKG pattern. It is also the ECG pattern known to residents and hospitalists all across this country as the boards type question for evidence of a pulmonary embolism. What does S1Q3T3 mean?

2021年7月14日 · S1-Q3-T3 refers to an EKG pattern first described in the 1930s suggestive of cor pulmonale in a case series of patients with pulmonary embolism (PE). This pattern has the following findings: Large Q wave in lead III. ST depression with an ascent to the T-wave in lead II (red arrows). T wave inversion in lead III (blue arrows).

as associated with a presentation of acute dyspnea and hypotension. It reveals sinus tachycardia, with a new appearance of a prominent S wave in lead I, a Q wave in lead III and T wave inversion in le. d III (and diffusely) suggestive of acute right ventricular strain. The CT angiogram revealed a massive saddle pulmonary embolus which req.
