106 Possible Causes for Inferior Q Wave

  • Posterior Myocardial Infarction

    […] fibrosis) Inferior MI Family (includes inferior, true posterior, and right ventricular MI's) Inferior MI Pathologic Q waves and evolving ST-T changes in leads II, III, aVF[ecg.utah.edu] Note that there is also some inferior STE in leads III and aVF (but no Q wave formation) suggesting early inferior involvement.[litfl.com] […] or poor R wave progression in leads V1-3) Pneumothorax (loss of right precordial R waves) Pulmonary emphysema and cor pulmonale (loss of R waves V1-3 and/or inferior Q waves[ecg.utah.edu]

  • Cardiomyopathy

    waves , particularly in the inferior (II, III, and aVF) and lateral ( I , aVL, V4-6) leads as signs of a hypertrophic septum Signs of left ventricular hypertrophy (see Sokolow-Lyon[amboss.com] Q waves in the septal leads may be present and arrhythmias, supraventricular and ventricular, occur in up to half of the patients.[revportcardiol.org] […] gallop due to thickened, non-compliant ventricle Possible murmur from mitral regurgitation Rapidly rising double arterial pulse in the carotid arteries ECG Abnormally deep Q[amboss.com]

  • Myocardial Infarction

  • Acute Myocardial Infarction

    ., Atrial fibrillation in inferior wall Q-wave acute myocardial infarction, Am J Cardiol., 1991,67 (13), 1135-1136 PubMed Crossref Google Scholar [26] Sinno H., Derakhchan[degruyter.com] Example 7 Anterior-inferior STEMI ST elevation is present throughout the precordial and inferior leads. There are hyperacute T waves, most prominent in V1-3.[lifeinthefastlane.com] In addition to anterior STEMI, other high-risk presentations of anterior ischaemia include left main coronary artery (LMCA) occlusion, Wellens syndrome and De Winter T waves[lifeinthefastlane.com]

  • Hypertrophic Cardiomyopathy

    Lateral Q waves are more common than inferior Q waves in HCM.[lifeinthefastlane.com] The classic finding is large, dagger-like “septal Q waves” in the inferior and lateral leads due to the abnormally hypertrophied interventricular septum.[healio.com] ) Q waves in the lateral inferior leads Giant precordial T-wave inversions in apical HCM Signs of WPW (short PR, delta wave).[lifeinthefastlane.com]

  • Cor Pulmonale

    The ECG often mimics myocardial infarction ; Q waves may be present in leads II, III, and aVF because of the vertically placed heart, but they are rarely deep or wide, as[health.am] […] in inferior myocardial infarction .[health.am]

  • Viral Myocarditis

    An isolated flipped T wave or an isolated Q wave in III or aVF is ok, but you can’t have the flipped T wave or Q wave in both those leads. “A flipped T is free in III.”[hippoed.com] […] a person is having an inferior wall STEMI.[hippoed.com] You will most commonly will see ST depression or downsloping of the initial part of the T wave in aVL. aVL is the most common lead in which you see reciprocal changes when[hippoed.com]
