A study on efficacy of autonomic nerve regulating agents on manifestation of accessory pathway in paroxysmal supraventricular tachycardia patients
- Conditions
- Paroxysmal supraventricular tachycardia (PSVT)
- Registration Number
- JPRN-UMIN000030753
- Lead Sponsor
- Hirosaki university hospital
- Brief Summary
Six patients showed fused atrial activation. Post-landiolol administration, the effective refractory period in AP stayed unchanged, while that of the AV node was prolonged. Wenckebach pacing rate via retrograde AV node decreased with landiolol, reducing the minimum ventricular pacing rate for atrial activation dissociation.
