| Many of these algorithms require identification of activation times from electrogram recordings which themselves may have complex morphology or low signal-to-noise ratio. |
| Figure 2 shows the electrogram from the atrial and ventricular leads while performing pacing in the cath-lab. |
| Recordings of LV electrograms may provide special diagnostic data unavailable solely from the standard right ventricular electrogram and corresponding marker channel. |
| An intracardiac electrogram monitoring device may be beneficial in high-risk patients by alerting them to rapidly progressive ST-segment changes indicative of acute coronary occlusion. |
| The second is a weekly session devoted to intracardiac electrogram analysis. |
| All electrogram data were checked manually. |
