Here we report a case of adenosine-sensitive focal atrial tachycardia that was successfully ablated from the left atrium at a site located adjacent to the posterior site of the left coronary cusp in spite of failed ablations from the superior-septal right atrium and non-coronary aortic cusp. ...
Adenosine, a naturally occurring nucleoside that slows conduction through the atrioventricular node, has recently been approved for the treatment of supraventricular tachycardia. It has been shown to convert patients with supraventricular tachycardia to sinus rhythm in up to 92% of cases. Its intravascula...
Atrial tachycardia (AT) can originate from the proximal coronary sinus (CS). However, detailed electrophysiologic characteristics of the tachycardia are not available. We describe the electrophysiologic characteristics, response to adenosine 5′-triphosphate, and results of radiofrequency ablation of AT ...
Paroxysmal Supraventricular Tachycardia Indicated for conversion to sinus rhythm of paroxysmal supraventricular tachycardia (PSVT), including that associated with accessory bypass tracts (Wolff-Parkinson-White Syndrome) Adenocard: 6 mg intravenous push over 1-3 seconds (maybe given as an intraosseous infus...
The sinus tachycardia appears to be mediated by adrenergic reflexes thought to be caused by activation of aortic arch chemoreceptors. Pulmonary vascular resistance, and, to a lesser extent, systemic vascular resistance decrease. Clinical Pharmacology Once it is injected into the bloodstream, adenosine ...
药效学 Adenosine is indicated as an adjunct to thallium-201 in myocardial perfusion scintigraphy and also indicated for conversion of sinus rhythm of paroxysmal supraventricular tachycardia. Adenosine has a short duration of action as the half life is 作用机制 Agonism of adenosine receptors A1 and ...
The negative chronotropic effects of adenosine produce transient sinus bradycardia followed by transient, but longer lasting reflex sinus tachycardia. Adenosine infusion produces coronary vasodilation resulting in increased coronary blood flow velocity without increasing myocardial work. Adenosine infusion also ...
We report the case of 22-year-old man who showed adenosine induced sinus tachycardia during the transesophageal electrophysiological evaluation for suspect... V Russo,AA Papa,A Rago,... 被引量: 0发表: 2014年 The method and effect to except the influence of unusual noise from automatic measured...
You should not be treated with adenosine if you have a serious heart condition such as "sick sinus syndrome" or "AV block" (unless you have a pacemaker), or slow heartbeats that have caused you to faint.Your doctor will perform tests to make sure you do not have conditions that would ...
Adenosine is indicated as an adjunct to thallium-201 in myocardial perfusion scintigraphy and also indicated for conversion of sinus rhythm of paroxysmal supraventricular tachycardia.12,13 Adenosine has a short duration of action as the half life is <10 seconds, and a wide therapeutic window.12,13...
