Key result
Continued digitalis therapy remains necessary in ~60% of patients with atrial tachycardia with block.
Why the study?
The clinical characteristics and management of atrial tachycardia with block, particularly in relation to digitalis intoxication, require clarification.
Does digitalis control congestive heart failure or rapid ventricular rate in patients with atrial tachycardia with block not caused by digitalis excess?

Does digitalis control congestive heart failure or rapid ventricular rate in patients with atrial tachycardia with block not caused by digitalis excess?
While atrial tachycardia with block is often associated with digitalis toxicity, it can occur independently and may require digitalis therapy for rate or heart failure control.
Morgan et al. (1962) conducted an observational in Atrial tachycardia with block (n=15). Digitalis was evaluated. Among 15 patients with atrial tachycardia with block, 9 were not due to digitalis excess and required continued digitalis therapy, whereas 6 had digitalis intoxication.
