Answer

In the outpatient setting, empiric therapies for recurrent paroxysmal supraventricular tachycardia (PSVT) may be instituted. These therapies may include beta-blockers, calcium channel blockers, and digoxin. A full discussion of these therapies lies outside the scope of this article (see Paroxysmal Supraventricular Tachycardia).

Further outpatient care includes the following:

  • If no arrhythmia is documented on ECG or telemetry, and symptoms occur on a daily basis, consider Holter monitor with diary to document cardiac rhythm during symptomatic episodes.
  • If no arrhythmia is documented on ECG or telemetry, and symptoms occur less frequently than daily, consider an event recorder to document cardiac rhythm during symptomatic episodes.
  • If patient is in stable condition and does not require hospitalization, and if no tachyarrhythmia has been documented but symptoms are induced by exercise, consider outpatient exercise treadmill testing.
  • If symptoms persist, but no tachyarrhythmia can be documented by any of these methods, consider referral to an electrophysiologist for an outpatient EP study.
