[Electrophysiologic effects of intravenous flecainide in intranodal junctional tachycardia in 30 patients].

The electrophysiological effects of flecainide acetate were studied in 30 patients (10 men, 20 women, mean age 48.3 +/- 18 years) suffering from sustained re-entrant intranodal tachycardia. A 2 mg/kg dose of flecainide administered over 10 minutes was given after the onset of sustained tachycardia within 3.

[Prognostic value of the hemodynamic study at rest and during the exercise test in 103 cases of primary dilated cardiomyopathies].

A population of 103 patients with primary dilated cardiomyopathy was studied and followed up for a mean period of 39.8 months. Several variables measured during maximum or symptom-limited exercise tests were compared with parameters recorded during haemodynamic exploration at rest, with the following results: 1.

[Oral propafenone in refractory arrhythmia. Apropos of 68 patients].

68 patients with rhythmical disorders unresponsive to treatment with one or several antiarrhythmics (quinidine derivatives 52 patients, amiodarone 28 patients, beta-blockers 24 patients) were treated by mouth with propafenone, with a mean postponement of 5.6 +/- 8.5 months (1 day to 33 months).
