1.5.3 Lead Connection and Evaluation
Lead Check –
Feature Description: Lead Check is a feature that, when activated, automatically measures the lead impedance with every pace. Based on these measurements, the lead configuration will be set to either unipolar or bipolar. Refer to Section 2.5 for more details regarding this feature.
Caution: Lead check will not lead to disabling of cardiac resynchronization therapy. It limits the use of the resynchronization features.
1.Lead check is possible only when the right ventricle is paced first.
2.Lead check works only when the pacing voltages are programmed between 2.4 and 4.8 V. The lead check feature can be programmed OFF in patients that require cardiac resynchronization therapy.
Care should be taken when programming Stratos
“Lead check may result in a switch to unipolar pacing and sensing, which may be inappropriate for patients with an ICD.”
Additionally, Lead Check should be programmed OFF before lead connection as the feature will automatically reprogram the device to unipolar in the absence of a lead.
