Pre-implant screening ensures thepa tient is a good candida te for S-ICDSys tem implant and therapy.
• Collect the surface ECG at theintended loca tion of the implantedpulse genera tor and subcutaneouse lectrodes .
• Ensure the entire QRS complex and Twave fit within the recommendedprofile for proper rhythm discriminationby the S-ICD Sys tem.
• Verify a t leas t one lead sens ing vectoris acceptable for a t leas t two pos tures(supine , s tanding, optiona l exercise )
