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).

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.

ECG abnormalities in such as PR displacement; late R in avR, slurred S in V1 or V2, the S1Q3T3 pattern and T wave inversion in V1 or V2 are significantly more common in patients with confirmed PE. Recognising the ECG findings could prompt clinicians to consider PE and lead to earlier diagnosis of the same. Patient consent: Obtained. 1.

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.

ECG showed sinus bradycardia, S wave in lead I, Q wave in lead III with T-wave inversion (S1Q3T3) (figure 1 A). Troponin T was negative and NT proBNP was elevated at 937 pg/ml. CT pulmonary angiography showed bilateral pulmonary embolism (figure 1 B).

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).

2020年4月17日 · 最近JACC上发表的一项回顾性研究（图2），明确指出，S1Q3T3在肺栓塞患者中出现率仅有10%左右（图3），这远远达不到我们期待的高敏感率、高特异性的标准，更不要提把S1Q3T3=肺栓塞了。 图2：JACC发表研究探讨S1Q3T3在肺栓塞诊断中的价值。 图3：影像学证实的肺栓塞患者中，S1Q3T3阳性率只在10%左右。 可怕的不是失败，而是信仰崩塌，信任多年的S1Q3T3不行了，是说心电图在肺栓塞的诊断中没有价值了吗？ 当然不是！ 这就需要我们从 …

The S 1 Q 3 T 3 sign (prominent S wave in lead I, Q wave and inverted T wave in lead III) is a sign of acute cor pulmonale (acute pressure and volume overload of the right ventricle because of pulmonary hypertension) and reflects right ventricular strain. 1 This electrocardiogram (ECG) finding is present in 15% to 25% of patients ultimately diag...

2016年6月12日 · Classic Triad of ECG findings – S1Q3T3. Reliability: ECG is neither specific nor sensitive for Pulmonary Embolism (PE) but it may one of the first indications of right ventricular overload. Summary: 1.

2018年1月1日 · classical changes are S1, Q3, T3; The detailed changes are as follows: tall R waves in V1; P pulmonale (peaked P waves) best seen in the inferior leads; there may be right axis deviation and clockwise rotation; atrial arrhythmias may occur; there may be T wave inversion in the leads V1, V2, V3; possible right bundle branch block
