Evaluation of Left Ventricular AutoThreshold

Evaluation of Left Ventricular AutoThreshold

This study will collect data on a new feature for future heart failure devices via an external non-implantable system.

ELEVATE is an acute, prospective, multi-center, feasibility study with a randomized within patient test sequence and pulse width, designed to characterize the performance of the Left Ventricular Auto Threshold feature.

Inclusion Criteria:

• Patients who are 18 or above, or of legal age to give informed consent specific to state and national law

Exclusion Criteria:

• Patients who have, or are scheduled to receive a unipolar LV pace/sense lead to be used with the CRT-P/CRT-D device, unless the patient has any commercially available epicardial leads with at least two electrodes (from one or more leads)
• Patients with pre-existing leads other than those specified in this investigational plan (unless the Investigator intends to replace them with permitted leads)
• Patients with a pre-existing unipolar pacemaker that will not be explanted/abandoned
