Abstract

Disopyramide (B 712) was tested in 39 patients with chronic arrhythmias of different kind: 23 cases with atrial fibrillation, 16 cases with ventricular ectopic beats, two cases with supraventricular tachycardias. The effect of disopyramide was compared to a pretreatment with one or several antiarrhythmic drugs (quinidine, beta-blocking agents, verapamil, ajmalin-bitartrat, aprindine, propafenone, diphenylhydantoin) which had been discontinued either due to ineffectiveness or the occurrence of intolerable side effects. Therapeutical effectiveness was controlled by on-line arrhythmia computers in the CCU or Holter monitoring. 15 patients were treated longer than 4 weeks up to 16 months (mean 35+/-22,6 weeks). The following results were achieved: 1 atrial fibrillation, abolition or significant reduction of the rate of recurrence in 10 out of 23 patients; slight reduction or no effect in 13 patients; 2. ventricular ectopic beats: abolition or significant reduction in 6 out of 16 patients, slight reduction or no effect in the remaining 10 patients. Patients who were treated successfully received the same dosis as those without therapeutical success. In cases with atrial fibrillation, the success was dependent on the duration of this...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
