adenosine injection does it stop the heart
Adenosine is given as a rapid injection into a vein (intravenously). Your heart will be monitored with an ECG while the medicine is being administered. Food and drinks containing caffeine such as tea, coffee, chocolate and cola should be avoided for at least 12 hours before you are given Adenocor injection. Atrial tachycardia. Atrial tachycardia is a less common type of SVT. It arises from a small area of tissue, anywhere in the atria of the heart. This area starts to fire and drive the heart, more rapidly than the heart's natural pacemaker. In most cases, there is no underlying cause for atrial tachycardia to occur. Tachycardia means a fast heart rate. Supraventricular means coming from above the ventricle. During an episode of supraventricular tachycardia (SVT), the heartbeat is not controlled by the SA node (the normal timer of the heart). Another part of the heart overrides this timer with faster impulses. Adenocor injection contains the active ingredient adenosine, which is a type of medicine called an anti-arrhythmic. Adenosine is also available without a brand name, ie as the generic medicine. Adenosine is a natural body chemical that is used to control abnormal heartbeats. The heart's pumping action is controlled by electrical signals that pass through the heart muscle. Inject Thallium-201 at the midpoint of the Adenosine injection infusion (i.e., after the first three minutes of Adenosine injection) •. Thallium-201 is physically compatible with Adenosine injection and may be injected directly into the Adenosine injection infusion set. Adenosine Injection USP, is indicated as an adjunct to thallium-201 myocardial perfusion scintigraphy in patients unable to exercise adequately. The recommended Adenosine injection dose is 0.14 mg/kg/min infused over six minutes (total dose of 0.84 mg/kg) (Table 1). This indirect negative inotropic effect of adenosine is also present in the human heart. Since increased amounts of adenosine are released during cardiac stimulation via beta-adrenoceptors, the indirect effect might protect the heart against excessive stimulation by catecholamines. Adenosine Dosage and Administration. The recommended Adenosine injection dose is 0.14 mg/kg/min infused over six minutes (total dose of 0.84 mg/kg) (Table 1). Supraventricular tachycardia (SVT) causes episodes of a fast heartbeat. 'Thumping heart' sensations (palpitations) and other symptoms may occur during each episode. Regular medication can prevent episodes of SVT. Another treatment option in some cases is to destroy a tiny part of the heart that triggers the SVT. [Article in German] Böhm M. Adenosine has a negative inotropic effect in cardiac atrial preparations (direct negative inotropic effect). This effect is probably due to an activation of a potassium outward current which shortens the action potential duration and hence reduces the force of contraction.
