Why the study?

Does the ability to induce paroxysmal tachycardia correlate with clinical arrhythmias in patients with Wolff-Parkinson-White syndrome?

Population

54 patients with pre-excitation (Wolff-Parkinson-White syndrome)

Design

Cross-sectional

Authors

PDPablo DenesNorthwestern University

Discussion

Member takes

Implication

Supports inducibility to corroborate symptoms in WPW; confirms association but leaves open prospective validation.

Key Points

To evaluate the inducibility of atrioventricular re-entrant paroxysmal tachycardia and examine its association with documented spontaneous arrhythmias in patients with Wolff-Parkinson-White syndrome.
Evaluated 54 patients presenting with ventricular pre-excitation.
Assessed the inducibility of atrioventricular re-entrant paroxysmal tachycardia using electrophysiological stimulation across patient subgroups categorized by spontaneous arrhythmia history.
Atrioventricular re-entrant paroxysmal tachycardia was successfully induced in 30 of 54 patients (56%) and was non-inducible in 24 of 54 patients (44%).
Tachycardia induction occurred in 20 of 20 patients with spontaneous paroxysmal tachycardia, 8 of 12 with paroxysmal atrial fibrillation, 5 of 14 with palpitation alone, and 1 of 12 asymptomatic patients.
The rate of paroxysmal tachycardia induction was significantly higher in patients with documented spontaneous paroxysmal tachycardia (P < 0.001) and paroxysmal atrial fibrillation (P < 0.01) compared with asymptomatic individuals.

Structured PICO

Does the ability to induce paroxysmal tachycardia correlate with clinical arrhythmias in patients with Wolff-Parkinson-White syndrome?

Population

54 patients with pre-excitation (Wolff-Parkinson-White syndrome)

Intervention

Tachycardia induction (electrophysiological testing)

Outcome

Incidence of documented spontaneous paroxysmal tachycardia

In patients with Wolff-Parkinson-White syndrome, the ability to induce paroxysmal tachycardia strongly correlates with a clinical history of spontaneous paroxysmal tachycardia.
