Summary
Rapid atrial stimulation (RAS) effectively treats paroxysmal supraventricular tachycardia (PSVT) when drugs fail. Transesophageal pacing and transvenous RAS offer alternative methods for terminating sustained PSVT.
Area of Science:
- Cardiology
- Electrophysiology
- Medical Devices
Context:
- Paroxysmal supraventricular tachycardia (PSVT) can be refractory to antiarrhythmic drugs.
- 19 patients with sustained AV nodal reentrant PSVT did not respond to various antiarrhythmic medications.
Purpose:
- To evaluate the efficacy of transesophageal pacing and transvenous rapid atrial stimulation (RAS) in terminating drug-refractory PSVT.
Summary:
- Transesophageal pacing successfully terminated PSVT in 10 patients, including 2 after verapamil administration.
- For 7 patients where transesophageal pacing failed, transvenous RAS successfully terminated PSVT, with 3 patients receiving verapamil prior to the procedure.
Impact:
- Demonstrates the effectiveness of pacing techniques, specifically transesophageal and transvenous rapid atrial stimulation, as alternative treatments for PSVT.
- Highlights the potential of RAS as a salvage therapy for patients with PSVT unresponsive to conventional antiarrhythmic drugs like verapamil.
