16 Possible Causes for Electrocardiogram Change, Inferior Q Wave, Pulsus Alternans

  • Myocardial Infarction

    A case was diagnosed as AMI if two out of the three criteria (clinical symptoms, electrocardiogram changes and raised enzyme levels) were positive.[dx.doi.org] (Example 2) Normal Inferior Q waves - not Old Inferior Wall Myocardial Infarction (MI) ECG Old Inferior Wall Myocardial Infarction (MI) ECG (Example 1) Old Inferior Wall Myocardial[healio.com] , electrocardiogram changes indicative of ischemia (ST segment elevation or depression), or coronary artery intervention (e.g., coronary angioplasty); or (2) pathologic findings[doi.org]

  • Cardiomyopathy

    The electrocardiogram pattern significantly changed with time, and the echocardiogram showed weakness of wall motion around the left ventricular apex.[ncbi.nlm.nih.gov] 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] Changes on your heart tracing (electrocardiogram, or ECG) - this is a tracing of the electrical activity of the heart. Changes on your chest X-ray.[patient.info]

  • Acute Myocardial Infarction

    But it was difficult to differentiate those two diseases because the TC-like findings; such as the electrocardiogram (ECG) changes and left ventricular wall motion abnormality[ncbi.nlm.nih.gov] ., 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] All patients had clinically significant electrocardiogram changes and significant myocardial injury, which can explain the increased AUC of hs-cTnT (0.97).[clinchem.aaccjnls.org]

  • Viral Myocarditis

    (RR 0.28, 95% CI 0.13 to 0.61), ST-T changes (RR 0.72, 95% CI 0.54 to 0.95), creatine phosphate kinase (CPK) levels (MD -21.54, 95% CI -33.80 to -9.28), and lactate dehydrogenase[ncbi.nlm.nih.gov] 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] […] of cardiac failure.A meta-analysis showed a significant effect ofAstragalus membranaceus injection plus supportive therapy on the number of participants with an abnormal electrocardiogram[ncbi.nlm.nih.gov]

  • Alcoholic Cardiomyopathy

    Leg elevation promptly reversed the pulsus alternans, and the echocardiographic abnormality.[ncbi.nlm.nih.gov] Subsequently they underwent intermittent nocturnal peritoneal dialysis with a changing cycle of 6-12 hours per session.[ncbi.nlm.nih.gov] Changes on your heart tracing (electrocardiogram, or ECG) - this is a tracing of the electrical activity of the heart. Changes on your chest X-ray.[patient.info]

  • Acute Myocarditis

    (ECG) [2] ECG changes are often nonspecific.[explainmedicine.com] Case Presentation: A 38-year-old female was presenting with chest pain and an increased level of troponins with the EKG (electrocardiogram) showing non-specific T-wave changes[jmmcr.microbiologyresearch.org] Abstract This case report describes changes in T wave compatible with an acute myocarditis found in a routine electrocardiogram taken on a young woman with generalized allergic[annals.org]

  • Heart Failure

    Acute cerebral injuries, such as cerebral ischemic or hemorrhagic events, have been repeatedly correlated with sudden electrocardiogram (ECG) changes, such as cardiac arrhythmias[ncbi.nlm.nih.gov] alternans (alternating large and small pulse pressures) and a raised JVP.[patient.info] Electrocardiography showed a sinus rhythm with Q-wave formation in the inferior wall leads (II, III, aVF), T-wave inversion in the same leads, and borderline QT prolongation[ncbi.nlm.nih.gov]

  • Dilated Cardiomyopathy

    Changes on your heart tracing (electrocardiogram, or ECG) - this is a tracing of the electrical activity of the heart. Changes on your chest X-ray .[patient.info] Pulsus alternans is an infrequent, complex pathophysiologic sign often associated with severe heart failure.[ncbi.nlm.nih.gov] Q waves in the septal leads may be present and arrhythmias, supraventricular and ventricular, occur in up to half of the patients.[revportcardiol.org]

  • Ischemic Cardiomyopathy

    Treatment might involve medicines, surgery, other medical procedures, and lifestyle changes.[icdlist.com] waves in leads I or AVL suggest a lateral epicardial exit, whereas Q waves in leads II, III or AVF suggest an inferior epicardial exit.[innovationsincrm.com] Electrocardiogram A normal ECG is not conclusive in the diagnosis of congestive heart failure. Changing ECG profiles are commonly observed in suspected HF cases.[symptoma.com]

  • Paroxysmal Ventricular Tachycardia

    The sequence can also be inverse, changing from atrial fibrillation to nodal reentrant tachycardia ( Figure 9 ).
