80 Possible Causes for Pulsus Alternans

Show results in: Deutsch

  • 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]

  • 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]

  • 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]

  • Heart Failure

    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] 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.medscape.com] Pulsus alternans (during pulse palpation, this is the alternation of one strong and one weak beat without a change in the cycle length) occurs most commonly in heart failure[emedicine.medscape.com]

  • Congestive Heart Failure

    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.medscape.com] […] oliguria Anorexia, weight loss, nausea Exophthalmos and/or visible pulsation of eyes Distention of neck veins Weak, rapid, and thready pulse Rales, wheezing S 3 gallop and/or pulsus[emedicine.medscape.com]

  • Sinus Arrhythmia

    Because the patients had pulsus alternans similar that observed in bigeminy, and because they did not have signs or symptoms of heart failure, we believe the arrhythmias represent[ncbi.nlm.nih.gov]

  • Secondary Cardiomyopathy

    To identify new prognostic indicators in idiopathic dilated cardiomyopathy (DCM) and secondary cardiomyopathy. Serum concentrations of aminoterminal propeptides of type III procollagen and the 7S domain of type IV collagen (7S collagen)--which have recently been used as indicators of collagen matrix turnover in[…][ncbi.nlm.nih.gov]

  • Acute Aortic Regurgitation

    Signs of the disease commonly include tachycardia, cyanosis, pulsus alternans, crepitations in the lungs indicating pulmonary edema and hypotension and peripheral vasoconstriction[symptoma.com] Physical Examination – Acute AR • Tachycardia • Peripheral vasoconstriction • Cyanosis • Pulmonary edema • Arterial pulsus alternans; normal LV impulse • Early mitral valve[slideshare.net]

  • Pulsus Alternans

    Pulsus alternans Pulse pressure waveform displaying the variation in pressure between beats in pulsus alternans.[en.wikipedia.org] A review of the current concepts on the pathophysiology of pulsus alternans is included.[ncbi.nlm.nih.gov] Pulsus alternans is typically found in patients with left ventricular systolic dysfunction.[ncbi.nlm.nih.gov]

  • 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.medscape.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.medscape.com]
