Outcome Measures

Primary Outcomes (1)

  • QLV measurement

    Measurements of the QLV interval is defined from the onset of the QRS width of the surface ECG to the first large positive or negative peak of the LV electrogram (EGM) during a cardiac cycle.

    15 minutes

Study Arms (1)

QLV interval measurement

EXPERIMENTAL

QLV measurements collected during implantation of CRT-D device

Procedure: QLV interval measurement

Interventions

Measurements of the QLV interval is defined from the onset of the QRS width of the surface ECG to the first large positive or negative peak of the LV EGM during a cardiac cycle. Recorded EGM's will be measured at three distinct points (basal, mid, and distal) within each target vessel.

QLV interval measurement
