71 Possible Causes for Pulsus Alternans

Show results in: Deutsch

  • Heart Failure

    alternans (alternating large and small pulse pressures) and a raised JVP.[patient.info] Pulsus alternans is usually associated with an S 3 gallop, signifies advanced myocardial disease, and often disappears with treatment of heart failure.[emedicine.medscape.com] Signs There may be a tachycardia at rest, low systolic blood pressure (BP), a displaced apex (LV dilatation) or RV heave (pulmonary hypertension), a narrow pulse pressure or pulsus[patient.info]

  • Congestive Heart Failure

    alternans (alternating large and small pulse pressures) and a raised JVP.[patient.info] alternans Increased intensity of P 2 heart sound Hepatojugular reflux Ascites, hepatomegaly, and/or anasarca Central or peripheral cyanosis, pallor See Presentation for more[emedicine.com] Signs There may be a tachycardia at rest, low systolic blood pressure (BP), a displaced apex (LV dilatation) or RV heave (pulmonary hypertension), a narrow pulse pressure or pulsus[patient.info]

  • Pulmonary Edema

    Serotonin syndrome (SS) is a potentially life-threatening condition resulting from excessive central and peripheral serotonergic activity. Clinically, it is a triad of mental-status changes, neuromuscular abnormalities, and autonomic disturbances. It can be caused by intentional self-poisoning, overdose, or inadvertent[…][ncbi.nlm.nih.gov]

  • Cardiomyopathy

    BACKGROUND: Coronary artery fistula, first described by Krause in 1865, is an abnormal communication between the coronary artery and one of the four chambers of the heart or one of the great vessels. The communications are often congenital but may also be acquired from trauma or invasive cardiovascular[…][ncbi.nlm.nih.gov]

  • Myocardial Infarction

    In cross-sectional studies in the general population, 15 to 40% of patients with ECG evidence of past myocardial infarction (MI) do not give a history of typical cardiac symptoms [ 1, 2, 3 ]. Mortality rates in patients with such “silent” MIs have been reported as higher than, similar to, or lower than those in[…][doi.org]

  • Acute Myocardial Infarction

    Ventricular septal rupture (VSR) is a rare but fatal complication of acute myocardial infarction (AMI) with an associated mortality that ranges from 41% to 80%. The treatment consists of supplemental oxygenation, afterload reduction, intraaortic balloon pump, and surgical repair. In selected patients, extracorporeal[…][ncbi.nlm.nih.gov]

  • Dilated Cardiomyopathy

    Pulsus alternans is an infrequent, complex pathophysiologic sign often associated with severe heart failure.[ncbi.nlm.nih.gov] Evaluation noted pulsus alternans, with beat-to-beat alternations in aortic pulse wave amplitude, both clinically and on diagnostic studies.[ncbi.nlm.nih.gov] Recognition of pulsus alternans is important as it provides significant clinical information, may suggest suboptimal medical management, and may be the first warning sign[ncbi.nlm.nih.gov]

  • Ischemic Cardiomyopathy

    Abstract BACKGROUND Ischemic cardiomyopathy is characterized by myocyte loss, reactive cellular hypertrophy, and ventricular scarring. However, the relative contribution of these tissue and cellular processes to late failure remains to be determined. METHODS AND RESULTS Ten hearts were obtained from individuals[…][doi.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]

  • Acute Myocarditis

    Abstract A 5-month-old boy was admitted to hospital presenting with cardiogenic shock. The echocardiographic examinations revealed a severe ventricular dysfunction. Despite the aggressive medical therapy, his hemodynamic status progressively deteriorated. Mechanical circulatory support was initially provided with[…][ncbi.nlm.nih.gov]
