Why the study?
Does an automatic dual-demand pacemaker improve refractory paroxysmal re-entry atrioventricular tachycardia in patients with Wolff-Parkinson-White syndrome?
Does an automatic dual-demand pacemaker improve refractory paroxysmal re-entry atrioventricular tachycardia in patients with Wolff-Parkinson-White syndrome?
Automatic dual-demand pacing was effective in half of the patients with refractory AVRT in WPW syndrome, but limited by sensing issues and high tachycardia rates in the remainder.
No takes yet. Share an insight, caveat, or question.
Automatic dual-demand pacing controlled refractory AVRT in half of WPW cases; leaves open its reliability due to sensing failures and high-rate ineffectiveness.
Curry et al. (1979) studied this question.
