Measurement of cardiac muscle relaxation in hypothyroidism.
The isovolumetric relaxation time of the left ventricle (IRT) in 20 hypothyroid patients (133 +/- (SE of mean) 4 ms) was significantly longer than that in 23 normal subjects (95 +/- 3 ms). During a trial of thyroxine replacement the IRT in 12 hypothyroid patients fell from 143 +/- 4 ms to 107 +/- 4 ms. The IRT seems to be a useful index of end-organ function in hypothyroidism.
متن کاملComparison of the effectiveness of muscle relaxation training in both face-to-face and distance methods on sleep quality in pregnant women with hypothyroidism
Background: One of the methods to prevent hypothyroidism is the use of non-pharmacological methods such as muscle relaxation, which can be taught in person or in absentia. The aim of this study was to compare the effectiveness of muscle relaxation training in both face-to-face and distance methods on sleep quality in pregnant women with hypothyroidism. Materials and Methods: This quasi-experim...
متن کاملCardiac tamponade in hypothyroidism.
To cite: Bajaj R, Mehrzad R, Singh K, et al. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2014-204076 DESCRIPTION Pericardial effusion in overt hypothyroidism is common (incidence 3–6%), but cardiac tamponade and pretamponade as a presentation in newly diagnosed hypothyroidism is rare. For patients diagnosed with cardiac tamponade without sinus tachycardia, hy...
متن کاملLoad-insensitive relaxation caused by hypoxia in mammalian cardiac muscle.
The relaxation of isolated cardiac muscles from mammals was recently shown to be sensitive to the loading conditions because the time course of relaxation could be changed by changing the load. This effect apparently is related to the amount and functional status of the sarcoplasmic reticulum. The purpose of this study was to determine whether hypoxia affected the load sensitivity of papillary ...
متن کاملEffect of Transient Congenital Hypothyroidism on Oxidative Stress in Cardiac Tissue of Adult Male Rats
Introduction: Increased oxidative stress is involved in the pathology of cardiovascular disease. Transient congenital hypothyroidism (TCH) leads to a variety of heart disorders during adulthood. In this study, the effect of TCH on antioxidant and oxidant systems in the serum and left cardiac ventricle of adult male rats was investigated. Materials and Methods: TCH was induced by administrating ...
