[R-wave augmentation in acute myocardial infarction (author's transl)].

In 18 out of 419 successive myocardial infarctions an increase in R-wave amplitude compared to the pre-infarction ecg had been observed. It concerned to leads III, aVF and II in posterior and inferior infarctions. The alteration of R-wave amplitude was accompanied by a dextroversion of electrical heart axis in the frontal plane. Direction of inscription of QRS loop changed in most cases. R-wave increase was demonstrated in the first ecg after the beginning of subjective symptoms and disappeared within few hours or days in general. Clinical course was rather serious in the cases described. As a pathophysiological mechanism of the phenomenon mentioned above either the influence of an injury potential upon ecg pattern or the presence of left posterior conduction defect is discussed.

[Potassium-dependent modification of the lidocaine effect: an experimental investigation (author's transl)].

Lidocaine was supplied to 10 cats by 2 comparative infusions of 7.5 mg/kg respectively. Once the drug was dissolved in a physiological and the other time in a K-Mg-concentrated electrolyte solution. The sequence of both infusions alternated. Serum potassium remained constant during infusion of the physiological electrolyte solution, but increased by about 1 mEqu/1 under K-concentrated solution. Lidocaine caused an enhancement of ventricular fibrillation threshold to an absolutely identical degree in both groups. Increase in cardiac output and stroke volume and decrease of sinus rate was significant in both groups, but more pronounced under K-Mg concentrated solution. Mean arterial pressure, peripheral vascular resistance, PQ, QRS, and QT interval remained constant on the whole. We deduce from these results for antiarrhythmic therapy on normokalemic patients, that the addition of potassium and magnesium to lidocaine solution does not enhance its antifibrillatory effect. This statement is valid for doses up to 20 mEqu/h of magnesium and 40 mEqu/h of potassium.
