  • systolic and diastolic
  • Torsion gives useful additional information about myocardial tissue performance in both systolic and diastolic function. (biomedsearch.com)
  • Objectives The purpose of this study was to test the hypothesis that in heart failure with normal ejection fraction (HFNEF) exercise limitation is due to combined systolic and diastolic abnormalities, particularly involving ventricular twist and deformation (strain) leading to reduced ventricular suction, delayed untwisting, and impaired early diastolic filling. (onlinejacc.org)
  • Conclusions In HFNEF there are widespread abnormalities of both systolic and diastolic function that become more apparent on exercise. (onlinejacc.org)
  • pathology
  • Critical care physicians can use comprehensive echocardiography as an extension of examination and further as a sophisticated tool when routine haemodynamics do not offer a clear solution for the specific abnormality or pathology. (biomedcentral.com)
  • cyst
  • In many cases the symptoms have low specificity, and can be similar to those of other genitourinary and gastrointestinal disorders, such as appendicitis, salpingitis, rupture of a corpus luteum cyst, miscarriage, ovarian torsion or urinary tract infection. (wikipedia.org)
  • salpingitis
  • Symptoms can include: Frequent urinary tract infections Pyelonephritis Obstructive voiding symptoms Urinary retention Failure to thrive Hematuria Cyclic abdominal pain Urolithiasis Cobra head sign is seen in radiography In females: salpingitis, hydrosalpinx with sepsis or torsion. (wikipedia.org)
  • suggests
  • Finally, it provides recommendations for CMR measurement protocols, attempts to stimulate standardization of torsion calculation, and suggests areas of useful future research. (biomedsearch.com)
  • genetic
  • those that decrease sperm motility such as sulfasalazine and nitrofurantoin Genetic abnormalities such as a Robertsonian translocation There is increasing evidence that the harmful products of tobacco smoking may damage the testicles and kill sperm, but their effect on male fertility is not clear. (wikipedia.org)
  • relaxation
  • Thus, relaxation of torsion is a direct measure of the deactivation of myocytes and release of stored elastic energy, both of which facilitate rapid filling. (biomedsearch.com)
  • 4 ) suggested on the basis of invasive hemodynamic studies that patients with HFNEF have significant abnormalities in active relaxation and passive stiffness, and concluded that the pathophysiological cause of elevated diastolic pressures and symptoms is abnormal diastolic function alone, because systolic function was considered normal.

  • syndrome
  • It is also believed that torsion (twisting) of the thoracic spine can cause blockage of the anterior radicular artery leading to Harlequin syndrome. (wikipedia.org)
  • clinical
  • This paper reviews current clinical applications and shows how torsion can give insights into LV mechanics and the influence of LV geometry and myocyte fiber architecture on cardiac function. (biomedsearch.com)
  • Disease
  • Recently there has been considerable interest in LV torsion and its relationship with symptomatic and pre-symptomatic disease processes. (biomedsearch.com)
  • Recent studies have highlighted a critical role for MLC2v phosphorylation in cardiac torsion, function and disease. (wikipedia.org)
  • primary
  • However Ultrasound imaging is necessary to visualize the testis if the hydrocele sac is dense to reveal the primary abnormality. (wikipedia.org)
  • The primary pathophysiological abnormality caused by this obstruction is related to the trapping of fluid within the intestine oral to the obstruction. (wikipedia.org)
  • causes
  • Common causes of strangulating obstruction are intussusceptions, torsion or volvulus, and displacement of intestine through a hole, such as a hernia, a mesenteric rent, or the epiploic foramen. (wikipedia.org)
  • significant
  • Same teams repeated a dual experiment during the annular solar eclipse of January 26, 2009, this time outside of the shadow zone, with the same significant correlation between the behavior of light torsion balances and a Foucault pendulum. (wikipedia.org)
  • similar
  • They also registered similar anomalies using a Foucault pendulum and a very light torsion balance, both located underground in a disused salt mine with minimal interference, during the partial solar eclipse of June 1, 2011. (wikipedia.org)
