56 Possible Causes for Pulsus Alternans, T Wave Inversion

  • Cardiomyopathy

    ECG T-wave inversion in right precordial leads (V 2 and V 3 ) 2. SAECG Late potentials seen on signal-averaged ECG 3.[ncbi.nlm.nih.gov] wave inversion, abnormal Q waves , nonspecific abnormalities Laboratory: troponin T ; , BNP Echocardiography : apical left ventricular ballooning , LVEF Coronary angiography[amboss.com] […] with no history of CAD, and frequent T-wave inversion.[aafp.org]

  • Myocardial Infarction

    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] ST segment depression and T wave inversion are associated with subendocardial infarction.[histopathology-india.net] Biphasic/inverted T waves in V1-5. Poor R wave progression (R wave height 3mm in V3). Abnormal Q waves and T-wave inversion in I and aVL.[lifeinthefastlane.com]

  • Acute Myocardial Infarction

    Features may initially be normal but abnormalities include new ST-segment elevation; initially peaked T waves and then T-wave inversion; new Q waves; new conduction defects[patient.info] This is because LBBB alone can produce signs that may be confused with those of infarction: deep QS waves in the right chest leads and ST depression and T wave inversion in[medicine-on-line.com]

  • Dilated Cardiomyopathy

    Pulsus alternans is an infrequent, complex pathophysiologic sign often associated with severe heart failure.[ncbi.nlm.nih.gov] Takotsubo cardiomyopathy is characterized by the basal hypercontractility and apical ballooning of the left ventriculum and T-wave inversion in the electrocardiogram.[ncbi.nlm.nih.gov] The main role of ECG is to detect evidence of myocardial ischemia (pathologic Q waves with ST elevation and T wave inversion in leads I, aVL, V 5, V 6 ) that might point to[transplantbuddies.org]

  • Fungal Myocarditis

    Once heart dysfunction sets in, signs of cardiac failure may manifest, such as pulmonary edema (fluid accumulation in the lungs), peripheral oedema, hypoxemia, pulsus alternans[medindia.net] Physical agents Electric shock Hyperpyrexia Radiation/radiotherapy Investigations ECG: changes may include ST-segment elevation/depression, T-wave inversion, atrial arrhythmias[patient.info] In one report, either ST-segment elevation or T-wave inversion was present as the most sensitive ECG criterion in 26 ].[intechopen.com]

  • Acute Myocarditis

    Abstract BACKGROUND: The pathophysiologic mechanisms and the prognostic meaning of electrocardiographic (ECG) T-wave inversion (TWI) occurring in a subgroup of patients with[ncbi.nlm.nih.gov] Thereafter, T-wave inversion typically ensues. The T-wave inversion may be discrete and lasts for one month.[ecgwaves.com] ST-abnormalities were defined as significant ST-segment elevation and/or significant ST-segment depression and/or T-wave inversion [ 7 ].[kjim.org]

  • Primary Cardiomyopathy

    […] with no history of CAD, and frequent T-wave inversion.[aafp.org] Patients present with an abrupt onset of angina-like chest pain, and have diffuse T-wave inversion, sometimes preceded by ST-segment elevation, and mild cardiac enzyme elevation[academic.oup.com] , and frequent T-wave inversion Echocardiography shows LVH of unknown etiology with reduction in ventricular chamber volume Pharmacologic therapy based on the 2005 ACC/AHA[aafp.org]

  • Hypersensitivity Myocarditis

    Physical agents Electric shock Hyperpyrexia Radiation/radiotherapy Investigations ECG: changes may include ST-segment elevation/depression, T-wave inversion, atrial arrhythmias[patient.info] Electrocardiography showed diffuse depression of the ST segment, inversion of the T wave, Q waves in leads V 1 and V 2 , and frequent premature ventricular contractions.[nejm.org]

  • Lymphocytic Myocarditis

    Markers of myocardial damage ( troponin or creatine kinase cardiac isoenzymes) are elevated. [10] The ECG findings most commonly seen in myocarditis are diffuse T wave inversions[en.wikipedia.org]

  • Ischemic Cardiomyopathy

    Because of the shortage of donor hearts, 16 (33%) of 48 patients with ischemic cardiomyopathy died awaiting transplantation. Determining factors that predict effective coronary revascularization and identifying patients who may benefit from revascularization is crucial. From 1984 to 1990, 207 ischemic cardiomyopathy[…][ncbi.nlm.nih.gov]
