Atrial tachycardia with block treated with digitalis.

ATRIAL TACHYCARDIA with atrioventricular block was first described by Sir Thomas Lewis in 1909.1 In recent years, Lown, Levine, and co-workers2-5 have emphasized the importance of digitalis intoxication as a cause of this arrhythmia. Other authors have also supported this concept.6' 7 Two large series describing the arrhythmia were published in 1943. Barker and coworkers8 found that digitalis w...

Digitalis and atrial tachycardia with block.

Atrial tachycardia with block is usually considered to be caused by digitalis intoxication. We have reviewed 44 episodes in 3I patients seen during the past three years. None of the patients fulfilled Lown's criteria for considering digitalis to be the common aetiological factor in atrial tachycardia with block. In our patients the concentration of serum digitoxin was between i5 and 25 nglml in...

[Paroxysmal atrial tachycardia with atrio-ventricular block].

PAROXYSMAL atrial tachyeardia with atrioventricular block (PAT with block) has been recognized more often in recent years since Lown and Levine clarified its diagnostic criteria and emphasized its important relation to digitalis excess.1' 2 The present report was prompted by the increasing frequency with which this diagnosis has been made at our hospital and its common association with chronic ...
