Why the study?
Does patient-controlled inductive right atrial pacing terminate episodes of refractory paroxysmal supraventricular tachycardia?
Does patient-controlled inductive right atrial pacing terminate episodes of refractory paroxysmal supraventricular tachycardia?
Patient-controlled inductive right atrial pacing can successfully terminate episodes of drug-refractory paroxysmal supraventricular tachycardia.
May offer rescue pacing for refractory PSVT; hypothesis-generating and leaves open need for controlled trials.
Two patients with a long history of paroxysmal supraventricular tachycardia are presented. The episodes of arrhythmia had been refractory to a wide variety of suppressive drugs and a significant deterioration in life style had resulted. Cardiac conduction studies demonstrated a re-entry mechanism, and it was possible to induce and terminate the tachycardia by appropriately timed electrical stimuli. The application of this principle to long-term control using inductive right atrial pacing is discussed. Both patients have repeatedly abolished episodes of tachycardia using this technique.
