13 Possible Causes for Increased Area of Cardiac Dullness, Non Specific ST-T Changes, Pulsus Alternans

  • Dilated Cardiomyopathy

    Pulsus alternans is an infrequent, complex pathophysiologic sign often associated with severe heart failure.[ncbi.nlm.nih.gov] Electrocardiogram revealed sinus tachycardia and non-specific ST-T changes in the lateral leads.[doi.org] Evaluation noted pulsus alternans, with beat-to-beat alternations in aortic pulse wave amplitude, both clinically and on diagnostic studies.[ncbi.nlm.nih.gov]

  • 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]

  • 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]

  • Toxic Myocarditis

    Kussmaul's sign A paradoxical increase in venous distention and pressure during inspiration. Finding associated with cardiac tamponade.[atsu.edu] The most common abnormality seen in myocarditis is sinus tachycardia with non-specific ST segment and T wave changes.[lifeinthefastlane.com] 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] ST-T changes in association with pericardial effusion Renal failure associated with severe kidney infection Autoimmune disease Medication When You Suffer Pericarditis During[pericarditispain.info]

  • Cardiac Tamponade

    Pulsus paradoxus was 20 mmHg. The electrocardiogram showed low-voltage QRS complex with electrical alternans.[ncbi.nlm.nih.gov] EKG 1,4 low voltage QRS, tachycardia, electrical alternans, PR depression, non-specific ST-T wave changes CXR 1,4 increased cardiac silhouette as compared to previous (most[emdocs.net] Physical exam reveals hypotension, muffled heart sounds, distended jugular veins, and positive pulsus paradoxus.[medbullets.com]

  • Pericarditis

    Considerable amounts of pericardial fluid may muffle heart sounds, increase the area of cardiac dullness, and change the size and shape of the cardiac silhouette.[merckmanuals.com] Patients also should be hospitalized if they have pulsus paradoxus, electrical alternans on the ECG, or a large pericardial effusion.[aafp.org] ECG: non-specific ST/T changes. Echocardiogram: mild pericardial effusion. Elevation of WBC count and CRP.[escardio.org]
