Symptom burden guiding invasive electrophysiological study in paroxysmal supraventricular tachycardia: The believe SVT registry
Authors' conclusion
EPS and ablation are safe and effective in preventing recurrence of nondocumented palpitations clinically suggestive of PSVT.
Study context
- Population
- Patients with palpitations highly suggestive of paroxysmal supraventricular tachycardia (PSVT), without ECG documentation of tachycardia or preexcitation, undergoing electrophysiological study (EPS)
- Participants
- 680 patients20 centres
- Outcome
- EPS findings
Methodological detailsEuropean tertiary hospitals
- European tertiary hospitals
Main finding
As reported in the abstract
Sustained tachycardia induced at EPS
60.9%
Substrate potentially enabling AVNRT
14.7%
Observational data: associations, not effects.
Further findings
Predictors of no recurrence
| OR | P value | |
|---|---|---|
| Ablation | 0.34 | P < 0.01 |
| Male gender | 0.58 | P = 0.01 |
Freedom from palpitations recurrence · 3.4-year follow-up
- Free of palpitations recurrence
- 76.2%
- Women free of palpitations recurrence after EPS
- 73%
Female proportion, recurrence vs asymptomatic during follow-up
- Female proportion among patients with recurrence vs asymptomatic
- 77.2% vs 63.5%, P < .01
Safety
- Major/permanent complications
- 0
- Minor/transient complications, diagnostic-only EPS
- 0.84%
- Minor/transient complications, EPS followed by ablation
- 1.8%
