2. Figure 1
Unipolar electrogram highlighting the relevant features of the morphology when evaluating effective capture of the left ventricular pace. All parameters are evaluated from after the ventricular pace to 170 ms later. BL = baseline; Max = peak positive amplitude; Min = peak negative amplitude; Tmax = time when Max occurred; Tmin = time when Min occurred.

3. Figure 2
Each bar represents an individual subject in the study. Colors represent the time spent in effective CRT (blue), ineffective CRT (green), and sensing (red). Subjects are ordered in increasing amounts of effective CRT. CRT = cardiac resynchronization therapy.

4. Figure 3
Percent effective CRT pacing vs %V pacing for each subject. Dashed line is the line of identity. CRT = cardiac resynchronization therapy; V = ventricular.

5. Figure 4
Example electrogram from a patient with atrial fibrillation (B021). Ineffective paced beats are highlighted with red circles. The label below each ventricular event is the device marker: BV = biventricular pace; VS = ventricular sense.

6. Figure 5
Examples of ineffective and effective pacing in a subject with LV latency (A002). A: Baseline electrogram morphology looks like complete loss of capture. B: When the LV is preexcited enough, there is an initial negative deflection, and effective capture can be seen. BiV = biventricular; LV = left ventricle.
