[Effectiveness and duration of action of nifedipine in effort angina (author's transl)].

The anti-anginal activity of nifedipine was studied after a dosage of 10 and 20 mg in nine patients suffering from a typical, stable effort angina pectoris. The effectiveness and the duration of action of nifedipine was evaluated by serial cycloergometer exercise testing repeated after the administration of the two dosage of nifedipine, for six hours. Nifedipine significantly increased exercise tolerance before angina pectoris, with an action lasting at least two hours after 10 mg and six hours after 20 mg. We also evaluated the changing of hemodynamic parameters (heart rate, blood pressure, double product) before and after the drug in the same day.

[Syncope during potassium depletion (author's transl)].

The onset of serious arrhythmias during potassium depletion occurs rather frequently in female subjects who have undergone hypotensive-diuretic treatment, independently from the duration and doses of drugs. These arrhythmias which produce a cardiac arrest, can also occur in subjects not affected with heart disease. They are not necessarily preceeded by clinical prodrumus or other types of minor arrhythmias not accompanied by other important electrocardiographic or serum-logical alterations of hypokaliemia. The most commonly observed type is the "torsades de pointe", though cases of ventricular tachycardia or ventricular fibrillation are also documented. The ethiopathogenesis is discussed with regard to the alterations of the basic electrocardiogram as well as to the kind of major arrhythmia. In most cases , lidocaine has given the most satisfactory thmias, results in the treatment of these arrhythmias, probably because of the modality of the action which is substantially different from the other antiarrhythmic drugs.
