Beta-adrenergic blocking agents are the drugs of choice to treat LQTS and include the following medications:

  • Nadolol
  • Propranolol
  • Metoprolol
  • Atenolol

Nadolol, however, is the preferred beta-blocker to be used at a dose of 1-1.5 mg/kg/day (once a day for patients older than 12 years; divided twice a day for younger patients). [3]
