- MATERNAL CARDIAC FUNCTION IN TWIN PREGNANCIES: A MODEL OF PREECLAMPSIA? // Heart;Nov2002 Supplement 4, Vol. 88, pIv33
Discusses an abstract of the study, titled 'Maternal cardiac function in twin pregnancies: A model for preeclampsia?,' by N. Kametas, F. McAuliffe, E. Krampl, J. Chambers and K.N. Nicolaides.
- Effect of head uptilt on HRV in female human subjects. D., Malini; M., Kalpana // International Journal of Biological & Medical Research;2014, Vol. 5 Issue 2, p3998
AIM: Cardiovascular autonomic response to orthostatic challenges are affected by cardiorespiratory fitness in adults. The mixed response to postural stress can be distinguished by changes in frequency components of Heart Rate Variability (HRV).Autonomic control via sympathetic and...
- High-Risk and IVF Pregnancies Exhibit Different Heart Rates vs. Normal Pregnancies. // Fertility Weekly;3/22/2004, p6
Presents the findings of a research conducted by Italian scientists and appearing in the "American Journal of Obstetrics and Gynecology" regarding differences of heart rate variability in high-risk, in-vitro fertilization and normal pregnancies.
- Utility of Corrected QT Interval in Orthostatic Intolerance. Kim, Jung Bin; Hong, Soonwoong; Park, Jin-Woo; Cho, Dong-Hyuk; Park, Ki-Jong; Kim, Byung-Jo // PLoS ONE;Sep2014, Vol. 9 Issue 9, p1
We performed this study to determine whether electrocardiographic corrected QT (QTc) interval predicts alterations in sympathovagal balance during orthostatic intolerance (OI). We reviewed 1,368 patients presenting with symptoms suggestive of OI who underwent electrocardiography and composite...
- Systemic inflammation, heart rate variability and air pollution in a cohort of senior adults. Luttmann-Gibson, Heike; Suh, Helen H.; Coull, Brent A.; Dockery, Douglas W.; Sarnat, Stefanie Ebelt; Schwartz, Joel; Stone, Peter H.; Gold, Diane R. // Occupational & Environmental Medicine;Sep2010, Vol. 67 Issue 9, p7
Objectives Short-term elevation of ambient particulate air pollution has been associated with autonomic dysfunction and increased systemic inflammation, but the interconnections between these pathways are not well understood. We examined the association between inflammation and autonomic...
- Low-dose steroid alters in vivo endotoxin-induced systemic inflammation but does not influence autonomic dysfunction. Alvarez, Sonia M.; Karavidas, Maria Katsamanis; Coyle, Susette M.; Shou-En Lu; Macor, Marie; Oikawa, Leo O.; Lehrer, Paul M.; Calvano, Steve E.; Lowry, Stephen F. // Journal of Endotoxin Research;2007, Vol. 13 Issue 6, p358
Severe injury and infection are associated with autonomic dysfunction. Diminished heart rate variability (HRV) is also observed as a component of autonomic dysfunction and is induced by endotoxin administration to healthy subjects. It is established that low-dose glucocorticoid administration...
- Reassessing the Role of QT[sub c] in the Diagnosis of Autonomic Failure Among Patients With Diabetes: a meta-analysis. Whitsel, Eric A.; Boyko, Edward J.; Siscovick, David S. // Diabetes Care;Feb2000, Vol. 23 Issue 2, p241
Presents information on a study which determined which characteristics of patients with diabetes are related to the accuracy of the autonomic testing portrayed Bazett's heart rate-corrected QT interval prolongation for autonomic failure. Correlates of QT prolongation; Gender differences in QT...
- Bupivacaine/diamorphine/phenylephrine. // Reactions Weekly;11/3/2007, Issue 1176, p8
The article presents the case of a pregnant woman who developed ventricular bigeminy while receiving phenylephrine for maintenance of normotension and bupivacaine and diamorphine for spinal anaesthesia. The woman's ventricular bigeminy persisted until delivery when she reverted to sinus rhythm....
- Fever in a pregnant woman returning from Africa. Pennachio, Dorothy L.; Kayali, Zeid; Kohli, Navjot; Dharkar, Dilip D. // Patient Care;7/30/2001, Vol. 35 Issue 14, p54
Presents the case of a pregnant woman who had fever after traveling to Ghana without taking prophylaxis against endemic diseases. Medical history of the patient; Results of laboratory examinations; Diagnosis of the disease; Treatment for the condition.
