The primary objective of this observational study is to show that ICD VR and DR patients presenting more than 50% cumulative right ventricular pacing percentage present significantly more therapies for Ventricular Tachycardia (VT)/Ventricular Fibrillation (VF)episodes compared to ICD patients presenting less than 50% cumulative ventricular pacing percentage during two years follow-up.

Detailed Description:

This protocol consists in a non-interventional multi-centre, prospective study.

The observational study will also answer the question of the impact of ventricular pacing on the outcome of patients implanted with ICD & CRT-D devices and how the ICD & CRT-D devices are used in clinical practice through two years follow up and will address the following:

Impact of ventricular pacing on patients outcome: impact of ventricular pacing on the incidence of VT/VF episodes for each models, incidence of atrial arrhythmia for each models, evolution of the cardiopathy (New York Heart Association NYHA Class, Left Ventricular Ejection Fraction LVEF), morbidity.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population

A total of 567 inclusions are required to demonstrate the main objective (global ICD/CRT-D implanted patients population).


Inclusion Criteria:

  • Patient implanted (primo implantation or replacement) with an ICD* from SORIN Group: Model OVATIO VR 6250, DR 6550, CRT 6750 models, or any similar or higher range device, that includes specific diagnostic and therapeutic functionalities, mandatory to make homogeneous the collection of data.
  • Patient has signed the informed consent for the use of her/his data (if applicable).

Exclusion Criteria:

  • Presence of a contra-indication to the ICD therapy.
  • Life expectancy less than 12 months.
  • Inability or refusal to provide informed consent to the data treatment if applicable.
  • Not available for routine follow-up visits.
  • Minors (<18) and pregnant women.
