Adenosin Life Medical® is an extremely fast-acting pharmaceutical for terminating paroxysmal supraventricular re-entrant tachycardia (PSVT) involving the AV node and diagnostic agent for locating accessory conduction pathways.
Adenosine terminates PSVTs in 10-45 seconds in 90-100% of cases.
Adenosine stress testing (echocardiography or myocardial scintigraphy) is indicated in patients with suspected coronary heart disease or unable to perform a normal exercise stress test.
Adenosine’s potent vasodilatory properties in resistance vessels in the heart cause a dose-dependent vasodilation chiefly in non-arteriosclerotic vascular beds.
Intravenous infusion of adenosine will produce a redistribution of the blood flow from arteriosclerotic vascular beds to more normal areas (coronary steal phenomenon) in patients with cardiosclerosis. At the same time, adenosine’s general vasodilatory effect brings out a reflexogenic increase in the inotropic and chronotropic effects of the heart, leading to increased cardiac work.
