![]() The adenosine test can therefore be used as a diagnostic test in patients in whom supraventricular tachycardia (SVT) is suspected, in which adenosine is used both for the induction of any arrhythmia. The main pharmacological effect of Adenosine is the rapid conversion of paroxysmal supraventricular tachycardias to sinus rhythm, including those associated with accessory conduction pathways ( Wolff-Parkinson-White syndrome ). What is the role of adenosine in the diagnosis and treatment of cardiac arrhythmias?Īt the level of the heart rhythm, adenosine decreases the heart rate and the speed of conduction of the heart impulse through the conduction system. Administration takes place only in continuous peripheral intravenous infusion. The dose of adenosine administration in case of coronary perfusion test is 0.14 mg/kg infused in 6 minutes. The use of adenosine enables the study of changes in blood flow within the coronary arteries, thus enabling the understanding whether there are stenoses that may have clinical significance.Įchocardiography with pharmacological stress (Ecostress with adenosine) is a diagnostic method that uses ultrasound to evaluate the anatomy and function of the heart and is performed with the intravenous administration of adenosine. In the heart and blood vessels, adenosine helps to dilate or expand blood vessels, in particular coronary vessels, and therefore improves the blood supply to the myocardium. How is the adenosine test performed to evaluate the function of the coronary vessels? However, this molecule has several physiological and pharmacological roles in the functioning of the normal organism, as well as in some pathological circumstances.
