Introduction: Intravenous adenosine is the first line treatment for SVT in infants and children. The recommended initial dose of adenosine in the RCPCH Medicines for children is 50 [micro]g/kg, followed by increments of 50 [micro]g/kg. The APLS guidelines su...
affects the AV node, adenosine is a useful diagnostic tool in patients with broad or narrow QRS complex tachycardia; it terminates arrhythmias dependent on the AV node, unmasks other supraventricular mechanisms during transient AV block, but almost always has no effect on ventricular tachycardia. Non...
By transiently slowing AV conduction, atrial activity is easier to evaluate from ECG recordings and therefore Adenocor can aid the diagnosis of broad or narrow QRS complex tachycardias. Adenocor may be useful during electrophysiological studies to determine the site of AV block or to determine, in...
Chemical structure of adenosine.Source: Public domain The cardiovascular uses of adenosine,a Class V antiarrhythmic drug, relate to its ability to block the AV node. Giving a 6 mg intravenous (IV) bolus followed by a saline flush can be helpful during a narrow complex tachycardia. This can te...
Adenosine has received wide acceptance as the drug of choice for initial treatment of supraventricular tachycardias (supraventricular tachycardia), and as a diagnostic adjunct in hemodynamically stable, wide-complex tachycardias. This report describes the successful use of adenosine for the treatment of ...
Misdiagnosis of wide complex tachycardias is still a common clinical problem. Because the electrophysiologic spectrum of action of adenosine is well characterized (Table 102-3), adenosine infusions for diagnostic purposes are potentially helpful.2122 Limitations to this proposed usage include the risk fo...

produce controlled hypotension. For practical purposes, in adults, a dose of 3 to 6 mg is given by IV bolus followed by a second dose of 6 to 12 mg after 1 minute if the first dose was not effective. This therapy rapidly interrupts narrow-complex tachycardia caused by AV nodal re...

The other three patients included one with a junctional rhythm, one with atrial fibrillation, and one with an undetermined narrow complex tachycardia. 49 patients had cardiac rhythm monitoring during adenosine administration. 17 of these patients had three or more consecutive ventricular beats following ...
