1.A graded test to measure an individual's heart rate and oxygen intake while undergoing strenuous physical exercise, as on a treadmill. 2.A test performed on a system or organization to determine its susceptibility to failure under various conditions. ...
3.Her heart rate dropped when you administered theadenosine. 你给予腺苷后 她的心率下来了 4.Caffeine affects theadenosinereceptors in the brain. 咖啡因会影响大脑中的腺苷受体 5.Ready six milligrams ofadenosineand get him up on the monitors. ...
Blood pressure, heart rate, end-tidal carbon dioxide, and sensory, motor, and reflex neurologic functions were examined for 24 h after injection of intrathecal adenosine doses of 0.25–2.0 mg (25 subjects) and either placebo or adenosine at 2 mg (40 subjects). The authors concluded that ...
Fast rhythms of the heart that are confined to the atria (e.g., atrial fibrillation, atrial flutter) or ventricles (e.g., monomorphic ventricular tachycardia) and do not involve the AV node as part of the re-entrant circuit are not typically converted by adenosine, however the ventricular ...
Incremental doses (10(-5), 10(-4), 10(-3), 2 x 10(-3), 5 x 10(-3), 10(-2), 10(-1), 1 mg) were selectively injected, at 5-min intervals, in a renal artery.Adenosine administration had no significant effects on blood pressure, heart rate and atrio-ventricular conduction. ...
1. 1. Adenosine (initial concentration 0.5 mM) disappears from the perfusion medium of an isolated, beating rat heart at a rate of 1.4 ωmoles/min per g myocardial protein. About 75% of the adenosine converted is recovered as inosine. 2. 2. Evidence is presented that the inosine is forme...
Numbness and tingling (paresthesia) Irregular heart rhythms (arrhythmia) Nausea Less common side effects of adenosine include: Chest pain Palpitations Ventricular arrhythmia Heart attack (myocardial infarction) Low heart rate (bradycardia) High blood pressure(hypertension) ...
An injectable form of adenosine is a US FDA-approved prescription drug for a condition involving rapidheart rate(paroxysmal supraventriculartachycardia). It is also used as a prescription drug to help measure blockages in thearteriesof the heart. People also use adenosine, AMP, and ATP assupplemen...
Polasek and M. Parizon and P.A. Roberts 摘要: Rats were anesthetized with urethane and limited occipital craniotomy was conducted to expose the caudal medulla in the region of the obex. Microinjections of adenosine were made into the nucleus tractus solitarius and heart rate and blood ...
