[Ventricular tachycardia "with reversal of points" and electrolyte disorders].

Ventricular tachycardia "with reversal of points" is described and its occurrence in electrolyte disorders (hypokalemia, hypomagnesemia), particularly in combination with antiarrhythmic drugs, is discussed. This ventricular tachykardia occurs in cases of disturbed and prolonged repolarization and is typified by periodically changing amplitude in the ECG ("reversal of points"). From the therapeutic point of view acceleration of heart rate by use of either sympathicomimetic drugs or pacemaker has proved successful. This distinguishes the treatment from that of other ventricular arrhythmias.
