Increased interbreath variability of gas exchange during exercise in children with cardiomyopathy.
نویسندگان
چکیده
D uring exercise testing in patients with chronic heart failure and severely depressed left ventricular function, an increased variability of gas exchange with a phenomenon of periodic breathing with an oscillatory pattern in oxygen uptake (VO2) has been recognised. 1 Previous studies were performed in adult patients with chronic heart failure related to ischaemic heart disease. The aim of the present study was to analyse whether an increased interbreath variability for gas exchange with an oscillatory pattern could also be identified during exercise in children with cardiomyopathy. Moreover, we also analysed whether this new parameter correlates with cardiac function.

متن کاملRight Ventricular Non-Compaction Cardiomyopathy in Children: Brief Review Literature
Right ventricular non-compaction cardiomyopathy (RVNC) is a genetic heterogeneous cardiomyopathy. Despite the increasing number of RVNC cases, the classification and natural history of this disorder are not completely clear. Also, because the pathogenic non-compaction cannot be easily differentiated from normal trabeculations, it is usually hard to accurately measure the prevalence of RV ...

متن کاملThe effects of different timings and severity of drought stress on gas exchange parameters of mungbean
Mungbean (Vigna radiata (L.) Wilczek) or green gram as a dryland grain legume is exposed to varied timings and severity of drought stress, resulting in variability in photoassimilate production. In order to evaluate some physiological responses in one mungbean cultivar to timing and severity of drought stress, a 3-replicate RCBD (randomized complete block design) field experiment was carried ou...
متن کاملEffects of Wearing N95 Respirators and Surgical Masks during Progressive Running Exercise and High-Intensity Interval Training on Time- and Frequency-Domain Indicators of Heart Rate Variability
Background and purpose: Wearing face masks has become popular during the COVID-19 pandemic as a measure to prevent the spread of the virus. Some studies have pointed out the intervening role of these masks in the effect of exercise on the cardiovascular system. This study aimed at examining and comparing the effects of masking (N95 respirators and surgical masks) and not wearing a mask during e...
