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.

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.

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 …

2017年2月10日 · The S1Q3T3 pattern describes the presence of an S wave in lead I, a Q wave in lead III, and an inverted T wave in lead III. This pattern was first described by McGinn and White in 1935, and is fairly well known as an indication of acute pulmonary embolism. Unfortunately it is not seen in all patients affected by PE.

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).

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).

Sinus tachycardia was defined as an increase in sinus rhythm to >100 beats/min. The S1 Q3 T3 pattern was defined according to the criteria of McGinn and White 15 (S wave in lead I and Q wave in lead III, with an amplitude of more than 0.15 mV (1.5 mm) associated with inversion of the T wave in lead III).

The S1 Q3 T3 pattern was defined according to the criteria of McGinn and White"5 (S wave in lead I Q lead III, with an amplitude of more than 0.15 mV (1.5 mm) associated with inversion of the T wave in lead III). Anterior subepicardial ischemic aspect (negative T waves) was defined by e presenc of pointed and symmetrical inverted T

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

2016年6月12日 · Synonym: Si/Qiii/Tiii; Interpretation: Deep S wave in Lead I: ≥1.5 mm; Q wave in Lead III: ≥1.5 mm; T wave inversion in Lead III; Neither sensitive nor specific; 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.
