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.

2013年12月3日 · T inversion in inferior leads can also occur in pulmonary embolism. Right axis deviation is another important feature of pulmonary embolism, which is also indicated by the S waves in lead I in the S1Q3T3 pattern. A case of pulmonary embolism with ECG showing S1Q3T3 pattern has been reported by Elaine Boey, Swee-Guan Teo and Kian-Keong Poh [1].

2019年1月25日 · ECG Quiz 42. Discussion. QRS axis has shifted to the right indicating right posterior hemiblock. rS complexes are seen in I and aVL. Wide QRS with notched R in V1, V2 is suggestive of right bundle branch block. The slurred S waves in I and aVL are also due to RBBB. PR interval is 200 ms. RBBB + LPHB constitutes one form of bifascicular block.

2024年2月24日 · Arrhythmogenic Cardiomyopathy was better known as Arrhythmogenic Right Ventricular Dysplasia or ARVD and sometimes as Arrhythmogenic Right Ventricular Cardiomyopathy or ARVC earlier. When left ventricular [1] and biventricular involvement became increasingly recognized, the terminology has been revised to Arrhythmogenic Cardiomyopathy. A study published in JACC has compared the phenotypic ...

2020年9月27日 · Chamber enlargements on ECG Atrial enlargement The normal P wave has a maximum amplitude of 2.5 mm (0.25 mV) and a maximum width of 2.5 mm (100 ms). In right atrial enlargement, the amplitude increases while in left atrial enlargement, it is the width (duration) which increases. Both increases in biatrial enlargement. P wave abnormalities […]
