A patient's own pacemaker; at a fixed rate its pacing spikes are an independent clock in the ECG.

Studies¶
| Study | Date | Status | Summary |
|---|---|---|---|
| Paced ECG as an independent clock | 2026-10-17 | current | Fixed-rate pacing gives a clock the recording chain cannot touch. Timing paced beats on three timelines shows that each SNUADC step-mode correction loses about 18 ms of signal, and that nothing else breaks the sample stream. |
