  Purpose

Physiological stimulation therapy effectiveness will be proved with contractility sensor or CLS sensor (Closed Loop Stimulation), in BIOTRONIK CLS pacemakers to prevent from neuromediated syncope. Furthermore, not only will be investigated if this system eradicates syncopes, but also if the number of presyncopal episodes is reduced.


Condition Intervention Phase
Syncope, Vasovagal
Device: Pacemaker with Closed Loop Stimulation (CLS sensor)

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Crossover Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Prevention

Further study details as provided by Spanish Society of Cardiology:

Primary Outcome Measures:
  • Reduction of number of syncopes [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    Demonstrate that pacing therapy regulated by an inotropic sensor (CLS) is effective for the suppression of the neuromediated syncope


Secondary Outcome Measures:
  • Time reduction to the first syncope [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    Time reduction to 1st syncope: Time from the implantation to the 1st recurrence of the syncope.

  • Reduction of the recurrence of presyncopal symptoms [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    Reduction of the recurrence of presyncopal symptoms: Since the CLS sensor can detect any changes in contractility, and presyncopal symptoms are preceded by a contractility increase, it is thought that CLS group patients will suffer less from these symptoms.

  • Improvement of Quality of Life [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    Improvement of Quality of Life: Syncope produces uncertainties and fear to the patients. This will be checked if pacemaker implant improves QOL of these patients and if a specific programming scheme influences the outcome.
