  • arrhythmias
  • At present, there are only anecdotal reports of cardiac arrhythmias in space, including one documented episode of non-sustained ventricular tachycardia. (wikipedia.org)
  • Concurrent with efforts by Flight Medicine to improve screening techniques, as NASA enters the era of exploration class missions, it will be critical to determine with the highest degree of certainty whether space flight by itself alters cardiac structure and function sufficiently to increase the risk for arrhythmias.

  • physiology
  • That same year Biology Graduates Jorge Negroni and Elena Lascano joined the investigation field and started their work in mathematical models for cardiac function comprehension next to Dr. Edmundo Cabrera Fischer, in charge of arterial function physiology. (wikipedia.org)
  • 1984
  • 1984) for obtaining ventricular volume is as follows: V = 1 α × ρ × L 2 × ( G − G P ) {\displaystyle V={\frac {1}{\alpha }}\times \rho \times L^{2}\times (G-G^{P})} where V is volume α is the alpha factor. (wikipedia.org)
  • chamber
  • CARP was originally identified as a YB-1-associating, cardiac-restricted transcription co-repressor in the homeobox NKX2-5 pathway that is involved in cardiac ventricular chamber specification, maturation and morphogenesis, and whose mRNA levels are exquisitely sensitive to Doxorubicin, mediated through a hydrogen peroxide/ERK/p38MAP kinase-dependent as well as M-CAT cis-element-dependent mechanism.

  • ALP functions to enhance the crosslinking of actin by alpha actinin-2 and also appears to be essential for right ventricular chamber formation and contractile function. (wikipedia.org)
  • Studies in ALP knockout mice have shown that ALP facilitates the cross-linking of actin filaments by alpha actinin-2, and absence of ALP induces abnormal right ventricular chamber formation, dysplasia and cardiomyopathy. (wikipedia.org)
  • Surgery
  • Weight reduction surgery is associated with substantial long term reduction in left ventricular mass. (ebscohost.com)
  • An abstract of the article "Weight reduction surgery is associated with substantial long term reduction in left ventricular mass," by Rajarshi Banerjee, Oliver Rider, Jane Francis, Cameron Holloway, Andrew Johnson and Stefan Neubauer is presented. (ebscohost.com)

  • Cardiopulmonary bypass (CPB) is a technique that temporarily takes over the function of the heart and lungs during surgery, maintaining the circulation of blood and the oxygen content of the patient's body. (wikipedia.org)
  • contractile function
  • An additional study showed that beta-adrenergic signaling via protein kinase A and CaM kinase induces the expression of CARP, and that CARP may have a negative effect on contractile function. (wikipedia.org)
  • normal
  • The ambulatory ventricular function analyzer system is carried by a garment worn by a cardiac patient and includes ECG electrodes, a main left ventricular probe detector, and a background lung probe detector for providing diagnostically useful information while the patient goes about the normal activities of daily life.

  • mice displayed normal cardiac function at baseline and in response to pressure overload-induced cardiac hypertrophy, suggesting that these proteins are not essential. (wikipedia.org)
  • A study investigating AARP function in cardiac muscle in which AARP was knocked out alone or in combination with the other MARPs showed that mice displayed normal cardiac function at baseline and in response to pressure overload-induced cardiac hypertrophy, suggesting that these proteins are not essential for normal cardiac development or in response to a hypertrophic stimulus.

  • 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. (wikipedia.org)
  • reduction
  • Despite a growing body of evidence suggesting that prolonged strenuous exercise (PSE) is associated with a transient reduction in right (RV) and left ventricular (LV) performance, the exact mechanism(s) responsible for this phenomenon is not fully understood. (biomedsearch.com)
  • pressure
  • However, one crewmember experienced a 5-beat run of ventricular tachycardia during a lower-body negative pressure protocol, and another had periods of "wandering supraventricular pacemaker" during rest and following exercise. (wikipedia.org)
  • Afterload is readily broken into components: one factor is the aortic pressure the left ventricular muscle must overcome to eject blood. (wikipedia.org)
  • citation needed] Disease processes pathology that include indicators such as an increasing left ventricular afterload include elevated blood pressure and aortic valve disease. (wikipedia.org)
  • Systemic hypertension (HTN) (elevated blood pressure) increases the left ventricular (LV) afterload because the LV must work harder to eject blood into the aorta. (wikipedia.org)

  • More recently, it has been shown that the corrected QT interval (QTc), a marker of ventricular repolarization, was prolonged slightly in a small number of astronauts after long-duration space flight. (wikipedia.org)
  • lung
  • An information processing sub-system including a microprocessor responds to the electrode signal and to the probe signals and provides composite data representative of the ECG activity, the background lung time-activity, the left ventricular time-activity, and an R-wave histogram averaged over multiple cardiac cycles.
