2024年10月8日 · Around 18% of patients with PE will have a completely normal ECG. However, with a compatible clinical picture (sudden onset pleuritic chest pain, hypoxia), an ECG showing new RAD, RBBB or T-wave inversions may raise the suspicion of PE and prompt further diagnostic testing

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.

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.

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.

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.

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 ...

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).

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...

2021年5月1日 · Clinically, massive PE was suspected along with electrocardiographic S1Q3 and S1Q3T3 features accompanied by T negativity at the D3 derivation based on prevalent T negativity. There was also right bundle branch block (RBBB), sinus tachycardia and …

SI QIII TIII pattern/S1Q3T3 – 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. The classic S1Q3T3 pattern, was first described by McGinn and White in 1935 (McGinn S, White PD. Acute cor pulmonale resulting from pulmonary embolism.
