SVT: Adenosine in asthmatic patient

Clinical bottom line

At worst adenosine is only relatively contraindicated in the treatment asthmatic patients with supraventricular tachycardia.


Using intravenous adenosine in asthmatics

Intravenous adenosine does not cause bronchospasm in asthmatic subjects, and supports the concept that adenosine-induced dyspnea is most likely secondary to stimulation of vagal C fibers in the lungs.

The increased intensity of adenosine-induced dyspnea in the asthmatic subjects suggests that airways inflammation may have sensitized the vagal C fibers.
