Outcome Measures

Primary Outcomes (1)

  • Rate of patients with LV latency >/= 40ms (stimulus to QRS onset) with respect to the total number of screened patients

    1 day

Secondary Outcomes (4)

  • Device-base measured LV latency in the LV IEGM channel and Far Field channel

    1 day

  • 12-lead ECG-measured LV latency in the channel with earliest QRS onset

    1 day

  • Device-based measured latency intervals (stimulus to electrogram peak and end) in the LV IEGM channel and the Far Field channel

    1 day

  • 12-lead ECG-measured latency intervals

    1 day
