Does verapamil alter ventricular rate patterns in digitalized patients with chronic atrial fibrillation?
Verapamil produces variable patterns of ventricular response in chronic atrial fibrillation, with some patients experiencing regularization of R-R intervals and others at potential risk for bradycardic complications.
Klein et al. (1984) studied this question.
