Determining an Acceptable Sense Vector
The physician must review the report and determine whether the patient
is suitable for implant of the S-ICD System. Confirm that the following
conditions are met:
• At least one common ECG lead must be deemed acceptable for
all tested postures. At a minimum, Supine and Standing/Sitting
postures must be tested.
• The morphology of the intrinsic/paced QRS complex is stable
across postures (similar positive/negative peak amplitudes and
QRS widths). No significant change to the QRS complex is noted
as a result of postural changes. For notched signals, ensure
that the location of the larger peak is consistent in relation to the
smaller peak.
NOTE: Special circumstances may present in which the
physician elects to proceed with the implantation of the
S-ICD System despite failing the screening process. In this
case, careful attention should be applied to the device setup
process of the S-ICD System as the risk of poor sensing and/or
inappropriate shock is increased.
