In patients with complete atrioventricular block and prolonged QT interval, correcting acquired risk factors like hypokalemia and implanting a pacemaker is effective in treating and preventing Torsades de Pointes.

May inform acute management of TdP in complete heart block; hypothesis-generating from single case and leaves open need for prospective validation.
Torsades de pointes (TdP) is a rare complication of a complete atrioventricular block with QT prolongation. Additional risk factors, such as hypokalemia, may increase the risk of TdP during atrioventricular (AV) block. We experienced a case of TdP, caused by a complete heart block and hypokalemia, which was successfully treated by implanting a permanent pacemaker and correction of the electrolyte imbalance.

Kim et al. (2004) conducted a case report in Torsades de pointes induced by complete atrioventricular block and hypokalemia (n=1). Permanent pacemaker implantation and electrolyte correction was evaluated on Recurrence of syncope or Torsades de pointes. Permanent pacemaker implantation and correction of hypokalemia successfully treated Torsades de pointes induced by complete heart block, with no recurrence during 10 months of follow-up.
