title: Slowing of ventricular rate quickly improved ventricular dysfunction and exercise intolerance in patients with chronic atrial tachycardia.
abstract: Three cases of chronic atrial tachycardia associated with ventricular dysfunction and severe exercise intolerance markedly improved within a few weeks when ventricular rate was slowed. Slowing ventricular rate may improve symptoms and ejection fraction despite possible changes in myocyte and tissue structure.
