High mortality persists despite termination; case reports leave open survival benefit amid severe comorbidities.

In patients with paroxysmal atrial tachycardia with block, often precipitated by digitalis, arrhythmia termination is frequently successful with potassium chloride, but overall mortality remains high due to severe underlying diseases.
Lim et al. (1974) conducted an observational in Paroxysmal atrial tachycardia with atrioventricular block (n=17). Clinical management including digitalis cessation and intravenous potassium chloride was evaluated on Mortality. Clinical management terminated the arrhythmia in 16 of 17 patients with paroxysmal atrial tachycardia with block, but the overall mortality rate remained high at 59%.
