Restoring sinus rhythm after intraoperatively occurring isorhythmic AV dissociation by the use of K-Mg aspartate or Mg aspartate.
In a prospective randomized clinical trial we tested the efficiency of different electrolyte infusions for the treatment of intraoperatively occurring isorhythmic AV dissociation (ID). Only infusions containing Mg were effective in restoring sinus rhythm: the infusion of K-Mg aspartate led to a conversion of intraoperatively occurring ID into sinus rhythm in 72% (p less than 0.01) of the patients and the infusion with Mg aspartate alone did so in 67% (p less than 0.01) of the patients. The rate of spontaneous conversion was 22% in the control group treated with Ringer's solution. The use of infusions containing K aspartate was ineffective in restoring sinus rhythm.
