Brief summary

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.

Interventions

DEVICEPacemaker with Closed Loop Stimulation (CLS sensor)

Crossover: 1 year at control group and 1 year at CLS group (randomized which group goes first)

Inclusion criteria

* Patients that fulfill the requirements of the study: * Patients with 5 previous neuromediated syncopes * Positive Tilt test, Cardioinhibitory response, heart rate \< 40 bpm for at least 10'' or pauses \> 3'' * Patient ≥ 40 years * No cardiopathy present * Patients without the following contraindications: * Drug treatment with β-blockers * Chronic Polyneuropathy * All contraindications for DDD or DDDR pacing (as per clinical guidelines SEC, 2002) * Geographically stable patients and able to attend all follow ups * Patients that have signed the informed consent

Exclusion criteria

* Patients that do NOT fulfill the inclusion criteria mentioned above * Patients with the contraindications indicated above * Patients with syncopes due to Carotid Sinus Hypersensitivity * Other syncope causes different to the CNS * Patients involved in other clinical studies * Pregnant women or in age bearing that are not using at least 2 contraception methods

Design outcomes

Primary

MeasureTime frameDescription
Reduction of number of syncopes1 yearDemonstrate that pacing therapy regulated by an inotropic sensor (CLS) is effective for the suppression of the neuromediated syncope

Secondary

MeasureTime frameDescription
Time reduction to the first syncope1 yearTime reduction to 1st syncope: Time from the implantation to the 1st recurrence of the syncope.
Reduction of the recurrence of presyncopal symptoms1 yearReduction 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 Life1 yearImprovement 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.
