15 صفحه اولEvaluation of Electrocardiogram Changes in Patients with Slow Coronary Flow
Background: Slow coronary flow (SCF) is defined as a condition in which in spite of no evidence of coronary occlusion or stenosis in angiography, there is delayed pacification of the vessels after the injection of a contrast agent. There are several studies about electrocardiogram (ECG) changes in these patients, but changes like OLD MI, RBBB, LBBB, LVH and ST-T wave have not b...
متن کاملCyclical variations in cerebral blood flow velocity.
Because little is known about spontaneous changes in cerebral blood flow in neonates, a newly developed online Doppler technique was used to insonate continuously the middle cerebral arteries of a group of sick (n = 20) and full term healthy (n = 16) newborn infants for a period of one minute. A total of 290 recordings of epochs each lasting one minute were analysed, and pronounced regular, cyc...
متن کاملRegional cerebral blood flow changes associated with ethanol intoxication.
Regional cerebral blood flow (CBF) was measured via the 133Xenon inhalation technique in 26 healthy volunteers before and 60 minutes after the oral administration of ethyl alcohol or placebo on a double-blind basis. The cerebral blood flow values, corrected for test-retest differences in carbon dioxide showed a significant bilateral increase after ethanol administration. Blood levels of ethanol...
متن کاملThe Effect of Acute Changes in Coronary Blood Flow
The effect of acute alterations in coronary blood flow (CBF) on left ventricular (LV) end-diastolic wall thickness was measured by reflected ultrasound in twelve anesthetized dogs. During five minutes of coronary ligation, wall thickness decreased from a control of 9.0 ± 0.3 mm to 8.1 ± 0.3 mm (P < 0.001); during reperfusion (reactive hyperemia), wall thickness was greater than control (10.2 ± ...
