OBJECTIVE To determine whether children with pallid breath-holding spells associated with bradycardia can be treated safely and successfully with permanent pacemaker implantation. METHODS The records of pediatric patients who had apparent breath-holding spells and associated bradycardia and were treated with permanent pacemaker implantation were reviewed. RESULTS Ten pediatric patients with...

Usually, coronary computed tomography angiography (CCTA) is performed during breath-holding to reduce artifact caused by respiration. The objective of this study was to evaluate the feasibility of free-breathing CCTA compared to breath-holding using CT scanner with wide detector. To evaluate the feasibility of CCTA during free-breathing using a 256-MDCT. In 80 patients who underwent CCTA, 40 we...

Objective: Cardiovascular changes are related to some of epilepsy disorders such as seizures and breath holding. The study objective was evaluate ECG findings in breath-holding febrile convulsion compared healthy individuals. Methodology: This Cross-sectional conducted on 270 children 90 with convulsion, patients 2019. Electrocardiography parameters of; QT interval, dispersion QT, corrected QTc...

Fourteen psychophysiological indices of response to hyperventilation and breathholding and to discrimination-conflict stress were combined with measures of neuroticism, motivation, and aptitude to form a correlation matrix including adjustment ratings obtained from 200 men during two successive cruises aboard a nuclear submarine. Patterns of psychophysiological indicators with adjustment criter...

As the clinical applications for 24-h ambulatory blood pressure monitoring expand, market demands increase, and there are now at least 13 manufacturers producing elaborate and expensive systems for recording 24-h ambulatory pressures. It is often difficult to assess the accuracy and performance characteristics of these devices and failure to standardize validation makes it difficult to compare ...

A cold model of a rotary holding furnace was studied using water and a kerosene-LIX973N organic mixture which are immiscible. The residence time distribution obtained showed that there was an optimum depth of the upper layer of organic where mixing with the bath fluid was maximised. The use of air bubblers showed that at low air flow rates, the air curtain acted to limit mixing but as the air f...

BACKGROUND The objective of this report is to combine the data from an earlier adult study with the data from a paediatric study in order to determine the overall accuracy of the BpTRU (BPM-100 model) as compared to the recognized standard, auscultatory mercury sphygmomanometer. DESIGN The individual blood pressure points recorded for both adult and paediatric studies were compared directly t...

BACKGROUND & OBJECTIVES Beta haemolytic streptococci (BHS), especially group A are still highly susceptible to penicillin. One possible explanation for this could be reduced growth capability in penicillin resistant BHS mutants. The present study was therefore undertaken to analyze the growth rates of BHS with decreased susceptibility to penicillin. METHODS Serial passages in the medium with ...

We explore prospects for detecting gravitational waves from stellar-mass compact objects spiraling into intermediate mass black holes (BHs) M approximately 50M to 350M) with ground-based observatories. We estimate a rate for such intermediate-mass-ratio inspirals of <or= 1-30 yr(-1) in Advanced LIGO. We show that if the central body is not a BH but its metric is stationary, axisymmetric, reflec...
