S1Q3T3 pattern on ECG in pulmonary embolism
2012年6月30日 · S1Q3T3 pattern in ECG is seen in acute pulmonary embolism [1]. 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 changes in pulmonary embolism - Johnson's Techworld
2013年12月3日 · Watch on. ECG changes in pulmonary embolism: The commonest finding on electrocardiogram in pulmonary embolism is sinus tachycardia. Pulmonary embolism can occur without significant electrocardiographic abnormalities. ECG may show right ventricular ischemia, incomplete right bundle branch block pattern or S1Q3T3 pattern (S waves in lead I, Q ...
McConnell sign in Pulmonary Embolism: Mechanism
2014年9月14日 · Though McConnell sign is useful in the bedside diagnosis of pulmonary embolism, it is not pathognomonic. It can occur in right ventricular infarction as well. A study compared 107 cases with pulmonary embolism (group 1) and 54 cases with right ventricular infarction (group 2). McConnell sign was noted in 70% group 1 and 67% in group 2 [3].

2009年10月25日 · ECG changes of myocardial ischemia. ECG changes of myocardial ischemia: Subendocardial ischemia produces ST segment depression while transmural or subepicardial ischemia produces ST segment elevation. It may be noted that subendocardium is more vulnerable to ischemia as collateral flow is more to the subepicardial region and extravascular ...

2008年12月16日 · This ECG also shows deep S waves in V2 and V3 which might indicate left ventricular hypertrophy. The tall T waves in V3 and V4 is more of a normal variant than that which could occur in hyperkalemia and hyperacute phase of myocardial infarction. The latter condition is often missed and mandates a repeat ECG if the clinical condition is suggestive.
