Short-duration head-up tilt test potentiated with sublingual nitroglycerin in suspected vasovagal syncope: the fast Italian protocol

Eur Heart JPublished

  • Randomised controlled trial
  • non-inferiority

Authors' conclusion

The diagnostic value of the Fast HUTT protocol is similar to that of the Traditional protocol and therefore the Fast protocol can be used instead of the Traditional protocol.

Study context

Population
Consecutive patients undergoing head-up tilt test (HUTT) for suspected vasovagal syncope
Participants
554 patients
Comparison
Fast vs Traditional nitroglycerin (NTG)-potentiated HUTT protocol
  • Fastn = 277
  • Traditionaln = 277reference
Primary endpoint
Positivity rate (induction of syncope in presence of hypotension/bradycardia)

Primary result

As reported in the abstract

Positive response

Further findings

Vasodepressor response

Vasodepressor response — Trend of lesser vasodepressor response with Fast, significant during the passive phase
P = 0.01
