Acute R Heart Strain-R heart/ inf. The ECG has been derided as being non-specific, missing many cases of PE, or only showing sinus tach. Become a Resus Member for FREE!

We identified 189 consecutive patients with suspected PE whose CT pulmonary angiogram (CTPA) was positive for a first PE and for whom an ECG taken at the time of presentation was available. Methods: A 21-point ECG scoring system was derived (relative weights in parentheses): sinus tachycardia (2), incomplete right bundle branch block (2), complete right bundle branch block (3), T-wave inversion in leads V(1) through V(4) (0 to 12), S wave in lead I (0), Q wave in lead III (1), inverted T in lead III (1), and entire S(1)Q(3)T(3) complex (2).

A case of head injury that raised a few questions, Head injury and blood thinners-When to Scan, Using Adrenaline the right way in Cardiac Resuscitation, Supraventricular tachycardias such as SVT or PE. Simultaneous T-wave inversions in the anterior (V1-4) and inferior leads (II, III, aVF). I recently was shown an ECG and asked what the patient’s diagnosis was. Analytical cookies are used to understand how visitors interact with the website. ECG changes in RBBB Diagnostic Criteria. S Wave in Lead I; Q Wave in Lead III; T Wave Inversion in Lead III; Findings with increased probablity of Pulmonary Embolism (especially moderate to severe PE) T Wave Inversion especially in anteroseptal (v1-v4) and possibly inferior (II, III, aVF) leads; Common Findings. The sensitivity, specificity, positive predictive value, and negative predictive value of this finding for the diagnosis of PE were 88%, 99%, 97%, and 95%, respectively. Most of us are walking around with PE’s and don’t know it. In those, you don’t need pulmonary embolism ECG findings to make the diagnosis. Inverted T waves in V1-V4; ST elevation in aVR; Atrial Fibrillation ; A constellation of these ECG findings or a Daniel score >5 can be used to risk stratify patients with RV failure secondary to PE who are at a higher risk for hemodynamic collapse. 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.

SIQIIITIII = deep S wave in lead I, pathological Q wave in lead III, and inverted T wave in lead III. S: mild concave and inferior STE, terminal QRS distortion in V2 (no S or J wave), hyperacute T wave V1-3 (as large as the QRS in V2 and larger than the QRS in V3) Impression: does not meet STEMI criteria but has multiple signs of OMI, and the Smith formula gives a value of 20.4 which is likely LAD occlusion.
