Cerebral blood flow-related signal changes during breath-holding.
BACKGROUND AND PURPOSE In the past, functional MR imaging techniques have been used successfully to determine cerebrovascular reactivity (CVR) to various stimuli, complementing the arsenal of functional brain investigations feasible with MR imaging. While previous studies have focused on blood oxygenation changes under vasodilatory stress, the aim of this study was to assess regional cerebral b...
متن کاملAssessment of breath holding index during orthostasis.
The aim of the study was to assess differences in cerebrovascular reactivity in healthy subjects during orthostasis. Twenty healthy volunteers (11 men and 9 women) with no atherosclerotic risk factors were evaluated by use of transcranial Doppler. The breath holding index (BHI) was obtained in supine and upright posture using standardized procedure. Student's t-test was used on comparison of th...
متن کاملThe Evaluation of Electrocardiography Parameters Changes in Breath‐Holding Children Compared to Controls
Background Breath-holding spells (BHS) are brief periods when young children stop breathing for up to 1 minute and are widely recognized types of non-epileptic severe occasions in early stages of childhood. This study aimed to evaluate QTd and QTc changes in children with breath-holding spells compared with healthy children. <stron...
متن کاملChanges in the period of no respiratory sensation and total breath-holding time in successive breath-holding trials.
1. Immediately after breath-holding at end-expiratory level, there is a certain period of no particular respiratory sensation which is terminated by the onset of an unpleasant sensation and followed by progressive discomfort during breath-holding. This period, defined as the time from the start of voluntary breath-holding to the point where the onset of an unpleasant sensation occurs, is design...
متن کاملElectrocardiography Parameters’ Changes in Epilepsy and Breath- holding children compared to Healthy Children
Background: Breath holding spells (BHS) are paroxysmal events with apnea and postural tone with Electrocardiography (ECG) abnormality and epilepsy status reports. The study aimed to compare the ECG parameters’ in epilepsy and breath-holding children compared with healthy children. Materials and Methods: </st...
