35 Possible Causes for Dyspnea at Rest, Pulsus Alternans, T Wave Inversion

  • Acute Myocardial Infarction

    After 48h following the accident, the patient's condition rapidly deteriorated, with severe dyspnea at rest, tachycardia, and increasing chest pain.[ncbi.nlm.nih.gov] 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]

  • 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]

  • Cardiomyopathy

    There are five useful clinical signs to establish the presence and severity of cardiomyopathy: general appearance (cachexia and dyspnea at rest indicate severe impairment)[clevelandclinicmeded.com] 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] […] mitral valve cusp towards the septum LVOT pressure gradient via doppler echocardiography Provocation tests (see below) are obligatory if no obstruction is discernible at rest[amboss.com]

  • Dilated Cardiomyopathy

    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] At presentation she had dyspnea at rest, orthopnea and paroxysmal nocturnal dyspnea.[doi.org] Pulsus alternans is an infrequent, complex pathophysiologic sign often associated with severe heart failure.[ncbi.nlm.nih.gov]

  • Secondary Cardiomyopathy

    These may include electrocardiogram (ECG) changes of QT prolongation and T wave inversion, elevated biochemical markers of myocardial damage and heart failure, and decreased[link.springer.com] Case presentation A 38-year-old Hispanic male presented with progressive dyspnea at rest since the morning, which became worse with exertion and lying flat.[bmcresnotes.biomedcentral.com] […] with no history of CAD, and frequent T-wave inversion.[aafp.org]

  • 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] Case 1: A 48-years-old, previously healthy male patient admitted to our clinic with complaints of acute onset of rest dyspnea and orthopnea, started the day before.[ncbi.nlm.nih.gov] Thereafter, T-wave inversion typically ensues. The T-wave inversion may be discrete and lasts for one month.[ecgwaves.com]

  • Fungal Myocarditis

    Physical agents Electric shock Hyperpyrexia Radiation/radiotherapy Investigations ECG: changes may include ST-segment elevation/depression, T-wave inversion, atrial arrhythmias[patient.info] A history of shortness of breath at rest, orthopnea, ankle edema, or paroxysmal nocturnal dyspnea is suggestive of congestive heart failure. 3.2 Chest pain Chest pain is usually[intechopen.com] 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]

  • Ischemic Cardiomyopathy

    There are five useful clinical signs to establish the presence and severity of cardiomyopathy: general appearance (cachexia and dyspnea at rest indicate severe impairment)[clevelandclinicmeded.com] They usually get progressively worse, if not treated Shortness of breath is initially related to physical activity and at later stages, may be present even at rest Difficulty[dovemed.com] […] lying flat on the bed (orthopnea) Gasping spells in the middle of the night (paroxysmal nocturnal dyspnea) Chest pain or pressure may be present along with the above symptoms[dovemed.com]

  • 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] […] on exertion or at rest, or edema that could be dated specifically to a one-to-two-day period), and a history consistent with the presence of a viral illness within the two[nejm.org] […] features had to be present for histopathologically borderline or active myocarditis to be classified as fulminant: fever, distinct onset of symptoms of heart failure (fatigue, dyspnea[nejm.org]

  • Viral Myocarditis

    On arrival at the ED a repeat EKG shows some ST elevations in V4-V6, without any reciprocal changes or T wave inversions.[hippoed.com] ABSTRACT: Children with acute myocarditis often present with dyspnea at rest, exercise intolerance, syncope, tachypnea, tachycardia, and hepatomegaly.[consultant360.com] Children with acute myocarditis often present with dyspnea at rest, exercise intolerance, syncope, tachypnea, tachycardia, and hepatomegaly. 9-12 Predominant respiratory symptoms[consultant360.com]
