Does temporary transvenous pacing suppress paroxysmal ventricular fibrillation in patients with hypomagnesemia?
Temporary transvenous pacing may be an effective treatment for paroxysmal ventricular fibrillation secondary to hypomagnesemia when pharmacological therapy fails.
Paroxysmal ventricular fibrillation unassociated with heart block occurred in two patients with hypomagnesemia. In neither patient were other causes of the arrhythmia apparent. Temporary transvenous pacing successfully suppressed the episodes after drug therapy failed. Prolongation of the Q-T interval was a prominent electrocardiographic feature in both patients and is postulated to have resulted from a loss of intracellular potassium secondary to hypomagnesemia.
Loeb et al. (Thu,) conducted a case report in Paroxysmal ventricular fibrillation with hypomagnesemia (n=2). Temporary transvenous pacing vs. Drug therapy was evaluated on Suppression of ventricular fibrillation episodes. Temporary transvenous pacing successfully suppressed paroxysmal ventricular fibrillation episodes in two patients with hypomagnesemia after drug therapy failed.
