Effects of adenosine on wavelength of premature atrial complexes in patients without structural heart disease.
Intravenous adenosine produced slight decreases in conduction times for premature atrial complexes but proportionally greater shortening of the functional refractory period. Decreased wavelength may provide a basis for transient atrial fibrillation, which is sometimes observed after adenosine administration.
