[Comparison between amiodarone and disopyramide in the treatment of ventricular extrasystoles].
The authors have compared the anti-arrhythmic activity and tolerance of disopyramide and amiodarone in the treatment of ventricular extrasystoles (VES) by using two quantitative methods of assessment. The stability of the rhythmic disorder was confirmed by two control Holter recordings in 20 patients without treatment, 16 of whom were bearers of an organic cardiopathy. The ventricular extrasystole was greater than 90 VES/hour in 18 patients. After the first control, Holter recording, each patient was treated successively with 400 mg of disopyramide/day in 4 doses for average period of 31 days, then a second Holter control recording without treatment, then 600 mg/day of amiodarone for 8 days followed by a maintenance dose varying from 200 to 400 mg/day: this second period of treatment lasted for an average of 38 days. The reduction of the number of VES was greater than 65 percent (SAMI criterion) in 2 of the 20 patients treated with disopyramide and in 13 of the 20 patients treated with amiodarone. Using the method of variance analysis, disopyramide was found to be efficacious in 5 cases out of 20 and amiodarone in 15 cases out of 20. Both methods indicate that the greater efficacy of amiodarone is statistically significant (p less than 0.01). All of those who did not respond to amiodarone were also non-responders to disopyramide.
