Adenosine-5'-triphosphate test for the noninvasive diagnosis of concealed accessory pathway.
OBJECTIVES This study assessed the use of adenosine triphosphate (ATP) in the noninvasive diagnosis of concealed accessory pathway (AP) and dual atrioventricular (AV) node physiology in patients with inducible AV reentrant tachycardia (AVRT). BACKGROUND Administration of ATP during sinus rhythm identifies dual AV node physiology in 76% of patients with inducible sustained slow/fast AV nodal r...
متن کاملInhibition by Adenosine 5'-Triphosphate
Two major species of glucose-6-phosphate dehydrogenase (EC 1.1.1.49) differing in size, pyridine nucleotide specificity, and susceptibility to inhibition by adenosine 5'-triphosphate (ATP) were detected in extracts of Pseudomonas multivorans (which has recently been shown to be synonymous with the species Pseudomonas cepacia) ATCC 17616. The large species (molecular weight ca. 230,000) was acti...
متن کاملAdenosine mapping for adenosine-dependent accessory pathway ablation.
BACKGROUND This study describes the use of adenosine during ablation procedures to allow conduction through adenosine-dependent accessory pathways (APs), which are inactive at the time of the procedure. The technique allows for successful mapping and ablation of these pathways. METHODS Retrospective review of all patients undergoing AP ablation from 1998 to 2008 to identify patients with abse...
متن کاملNoninvasive diagnosis of dual AV nodal physiology in patients with AV nodal reentrant tachycardia by adenosine triphosphate test.
Atrioventricular nodal reentrant tachycardia (AVNRT) is a relatively common paroxysmal supraventricular tachycardia. This study investigated whether adenosine-5'-triphosphate (ATP) injection during sinus rhythm might be useful in the noninvasive diagnosis of dual AV nodal pathways. The study group consisted of 9 patients with slow/fast AVNRT and 11 control patients without antegrade dual AV nod...
متن کاملParadoxical preexcitation following successful ablation of a concealed accessory pathway
Catheter ablation is an established curative treatment for accessory pathways (APs), but in spite of the great progress made in the diagnosis and treatment, there is limited knowledge of the underlying cellular pathophysiology that determines the different clinical presentations. The case presented highlights the complex presentation and properties of some APs that can be encountered at the tim...
