[Hypomagnesemia and hypokalemia as risk factors of arrhythmia in acute phase myocardial infarction].

In a uniform group of 30 patients the A. have assessed the incidence of lower serum K+ and Mg++ concentrations on the probability of arrhythmias onset in the acute phase of myocardial infarction. The study shows that lower K+ and Mg++ levels significantly influence only the onset of ventricular tachycardia and monofocal PVC.
