18 Possible Causes for Increased Area of Cardiac Dullness, Pulsus Alternans

  • 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]

  • Cardiomyopathy

    Cardiomyopathy can be acquired or inherited. “Acquired” means you aren’t born with the disease, but you develop it due to another disease, condition, or factor. “Inherited” means your parents passed the gene for the disease on to you. Researchers continue to look for the genetic links to cardiomyopathy and to[…][web.archive.org]

  • 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

    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]

  • Alcoholic Cardiomyopathy

    Leg elevation promptly reversed the pulsus alternans, and the echocardiographic abnormality.[ncbi.nlm.nih.gov] Application of a small dose of glyceryl trinitrate paste (0.25 in) resulted in severe left ventricular dysfunction with the appearance of pulsus alternans in a patient with[ncbi.nlm.nih.gov]

  • Primary Cardiomyopathy

    Abstract Eleven patients with hypertrophic obstructive cardiomyopathy and eight patients with idiopathic congestive cardiomyopathy underwent extensive neuromuscular studies to determine if a skeletal myopathy is associated with uncomplicated primary cardiomyopathy. The clinical examination revealed peripheral[…][ncbi.nlm.nih.gov]

  • Peripartum Cardiomyopathy

    Peripartum cardiomyopathy (PPCM) is a form of dilated cardiomyopathy that is defined as a deterioration in cardiac function presenting typically between the last month of pregnancy and up to six months postpartum. As with other forms of dilated cardiomyopathy, PPCM involves systolic dysfunction of the heart with[…][en.wikipedia.org]

  • Aortic Valve Stenosis

    Pulsus alternans can occur in the presence of LV systolic dysfunction.[emedicine.medscape.com] Other symptoms of aortic stenosis include the following: Pulsus alternans: Can occur in the presence of left ventricular systolic dysfunction Hyperdynamic left ventricle:[emedicine.com] In severe aortic stenosis, the carotid arterial pulse typically has a delayed and plateaued peak, decreased amplitude, and gradual downslope (pulsus parvus et tardus).[emedicine.com]

  • Toxic Myocarditis

    Kussmaul's sign A paradoxical increase in venous distention and pressure during inspiration. Finding associated with cardiac tamponade.[atsu.edu] Ewart's sign An area of dullness to percussion at the tip of the left scapula Decreased or muffled heart sounds More common when large amounts of fluid are in the pericardium[atsu.edu]

  • Suppurative Pericarditis

    Patients with large pericardial effusions have an area of increased dullness at the base of the heart in addition to generalized enlargement of the area of cardiac dullness[tele.med.ru] alternans 交互脈 pulsus paradoxus 奇脈 pupillary reaction 瞳孔反応 pure gonadal dysgenesis 純型性腺形成不全 pure red cell aplasia 赤芽球癆 PRCA purified protein derivative 精製ツベルクリン PPD purine[jpeds.or.jp] Kussmaul's sign A paradoxical increase in venous distention and pressure during inspiration.
