S-ICD (subcutaneous implantable cardioverter-defibrillator) screening failure occurs in about 10% of cases. Predictors of screening failure are not yet well determined. Moreover, slight variations in electrode positioning may change vector configuration and therefore improve screening success rates
S-ICD (subcutaneous implantable cardioverter-defibrillator) has become the last years widespread in various pathological conditions and implantation rates are increasing each year worldwide. Previous to implantation it is mandatory to realize a screening in order to assess specific electrocardiographic vectors used to analyze cardiac rhythm. In routine practice, approximatively 10% of patients are recused for S-ICD device implantation due to failed screening 1-3. Causes are mainly abnormalities of R wave (low or high amplitude) and low R/T wave ratio. Determinants for screening failure have not yet been clearly studied. Moreover, it is a common finding in S-ICD implantation to find variations between pre-implant electrograms and electrograms recorded by the device. Variations of R wave amplitude and R/T ration are also observed with small variations of electrode positioning prior to implantation. It has been also shown that despite initial screening failure, S-ICD could be securely performed in some cases 4,5. Patients included in the study will undergo usual screening protocol. In case of failure a 2nd screening will be realize with slight electrode positioning variations compatible with S-ICD and lead placement. In case of success modality of implantation will be decided by physician.
In case of S-ICD implantation screening data will be compared to post implantation device electrograms. A 2 month follow-up will be performed with comparison of a new screening procedure with electrodes at the level of sub-cutaneous electrodes.

Solution titration in which the end point is read from the electrode-potential variations with the concentrations of potential determining ions. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
The identification of selected parameters in newborn infants by various tests, examinations, or other procedures. Screening may be performed by clinical or laboratory measures. A screening test is designed to sort out healthy neonates (INFANT, NEWBORN) from those not well, but the screening test is not intended as a diagnostic device, rather instead as epidemiologic.
An electrochemical technique for measuring the current that flows in solution as a function of an applied voltage. The observed polarographic wave, resulting from the electrochemical response, depends on the way voltage is applied (linear sweep or differential pulse) and the type of electrode used. Usually a mercury drop electrode is used.
Surgical procedure in which the STOMACH is transected high on the body. The resulting small proximal gastric pouch is joined to any parts of the SMALL INTESTINE by an end-to-side SURGICAL ANASTOMOSIS, depending on the amounts of intestinal surface being bypasses. This procedure is used frequently in the treatment of MORBID OBESITY by limiting the size of functional STOMACH, food intake, and food absorption.
A surgical procedure which diverts pancreatobiliary secretions via the duodenum and the jejunum into the colon, the remaining small intestine being anastomosed to the stomach after antrectomy. The procedure produces less diarrhea than does jejunoileal bypass.
